Exchange Server question

[CrOtALiTo]

Do you have hosting service?
Look I bought a hosting service on Mexico, but I can't do a relay from my exchange server to my server, because the company what gives the service doesn't has the service available and well just I need to find a service for I can keep a website and also I need to have a lookup DNS for my Exchange server.

That service you have currently has that service?

I'm having a little trouble understanding precisely what you require. Are you in need of a DNS server? If so, they are freely offered from companies like Google (I can post you a link if you want, but search for "free dns server" and you'll find a lot).

If you are looking for a host that provides an Exchange server for your local client to connect to, that is not something my host (midPhase) provides with my plan. Generally servers with Exchange are more expensive since they need to license the software from Microsoft.

If you are running your own Exchange server on your local system, then I am confused about your question and request that you give me more details. Are you wishing to allow other people to connect to your local system through some website address? This could be accomplished with free services like the site called no-ip (again a Google search will find you the link) which allow you to associate a specific website URL with your dynamic local IP address.

Yes precisely I have installed in my office a Microsoft Exchange server for the use of my employees, but as I told you before, what I hired a service of MX on my country trough of the website www.nic.mx and well certeinly they can't offer me the DNS Server as relay in my server, because they use all their system with Linux and it can't be possible as an alternative for me, then I'm searching a service where I can get a DNS service relay or DNS Look- up like to a DNS server with IP address.

Because I can send in my intranet e-mail between us, but I cannot send e-mails out of my intranet to other domains server, then I have in needed to send e-mail outside of my network.

For that reason I was asking you if your console use consoles DNS or if your provide hosting give you that choice.

I have tried with DynDNS.org before, but they a similar choice or service for me, but only they give me a Look up DNS for my Exchange server trough of their server with a limiting of that I can send more than 500 MB per day and it doesn't work for me, already my service require more than 500 MB per day, so I'll can send more files bigger, then I need a service with more bandwidth for my server.

Therefore I slip buying by a year with nic Mexico the service that finally didn't work for me and well now I need to find other service what it can gives me the I need in really, nonetheless I believe what I can do a bridge with a server with good DNS installed.

For that my question.

Best regards.

[Tarential]

Hmm now I'm more confused than before.

Do you mean that you registered your own domain? That site is a registrar so I assume it is what you meant.

DNS is completely independent of operating system. It is a network protocol that can be accessed by any IP compatible device. It is simply a translation of a website URL (ie www.google.com) to an IP address (74.125.127.106) or even multiple IP addresses (for backup servers). So if they are using a Linux based DNS server, you can still have your exchange server access it.

Sorry, but I completely do not understand what you mean by this sentence. What is a DNS service relay? I've never heard of it. Neither has Google. I've heard of a DNS relay cache on a router, but that is simply a local DNS server that stores commonly used URLs, it can't be what you need.

If I understand this correctly I must come back to my original question: Do you simply need a DNS server so that your Exchange server can translate, say, billy@yahoo.com into the proper server IP? I don't see what else you could be asking for.

I have to assume here by "console" you mean my "Internet service provider (ISP)". Yes I use my ISP's DNS server because it is the fastest. I don't believe that my web host provides a DNS server -- I see no reason it would. After all, there are many free ones available, plus all ISPs offer one.

DynDNS is a service similar to No-IP, but I must clarify here that they are not really DNS servers. They simply offer redirects from their servers to your home IP (which they track with your help). If this is the kind of service you are looking for then for clarification please call it a "dynamic IP tracking system" or something similar.

I would really like to help but the terms you are using to describe your problem are not used that way in English. Perhaps there is someone else here who is knowledgeable about computers and speaks Spanish fluently who can assist with the translation or the problem itself. If not, I'll try to do what I can anyway.

[CrOtALiTo]

Thank you for the help.

Only I want a DNS service from any place, for what I can send e-mails out of my intranet.
And I know what is a DNS.

[Tarential]

My friend, this cannot be all you require. If so, there is no reason for any of this. I will give you Google's free ones here like I suggested you search for in my first reply:
Primary DNS: 8.8.8.8
Secondary DNS: 8.8.4.4

They are free, there is no need to buy any service or set up an account.

But I suspect you need something else besides a DNS server, or I don't understand why there was this big problem. DNS servers are very common and not difficult to acquire. Your personal computer must of a necessity already know a DNS server, which it likely got through the DHCP protocol from your router which in turn got it from your ISP. You could easily use your ISP's DNS server if you wanted to, because that is part of what you pay them for.

I cannot stress this enough: I am not trying to be rude, but the words you choose to use do not show an understanding of the concepts involved. I assume that this is because of an error in translation, not an error in your understanding. Yet the error exists, and it is making it very difficult for me to help. I think, if you are not looking for a DNS server as I have posted a solution to twice already, that someone else who speaks Spanish fluently would be better suited to help you than I.

Tengo instalado un Microsoft Exchange Server en mi servidor, la cual he creado la cuentas necesarias para poder enviar correos por medio de SMTP a traves de mi red solo adentro de mi red, entonces ahora requiero enviar correos fuera de mi red como servidores Hotmail or Yahoo or otros servidores cualquiera en la internet, pero no puedo porque no cuento un DNS relay o un servicio de DNS para configurar mis conectores de internet en Server Exchange.

Te digo compre un servicio de dominio en www.nic.mx, pero eso no me funciono porque ellos no manejan esos servicios entonces te pregunte si tienes en tu consola el servicio de Lookup DNS para enviar correos por medio de un servidor Exchange osea que pueda configurar mi conectores con alguna IP fija o dedicada y pueda enviar a traves de esas DNS salgan a internet los correos del Server Exchange.

I hope can you understand in Spanish my requiring.

Se que hay servicios de DNS gratuitos en internet, pero ellos solo te ofrencen el redireccionamiento gratuito mas no hosting.
Entonces tu me estas explicando sobre el uso de la DNS la cual ya lo se, solo requiero el servicio y si conoces alguno.

Saludos.


Look I can give you an idea about what truly I need with the DNS.

Please read this.

I have installed MS Exchange Server, in which I have created the necessary accounts so that I could send mail through SMPT using as an intranet mean, but now I need to send mail outside my net using services such as Hotmail or Yahoo or other servers, but I can't because I lack a DNS relay or DNS service to configure mi connectors to internet in the Exchange Server.

....the service to www.nic.mx didn't work for me because they don't handle those services, then I asked you if you have, in your console, DNS service to send mail through a server from Exchange, in other words, that I could configure my connectors with a fixed or dedicated IP so that I can send through those DNS out to the internet the mail from Exchange...

(sorry, I made my best)

[CrOtALiTo]

Thank you Chileno for the translation.

This message you posted:
"The MailHop® Outbound allows you you to send mail from anywhere by using our secure, authenticated outbound SMTP relay server. You can reach it on networks which block common mail servers since you can reach it on standard and non-standard ports. Whether your ISP does not allow you to send mail or if you are somewhere that has no outgoing mail server, MailHop Outbound lets you send mail."

This implies that you are trying to send mail and that your ISP is blocking the SMTP ports. What you require, if that is so, has nothing to do with DNS. Honestly, your continued mentions of lacking DNS relay/service is just confusing me. I have re-read all your posts from the first and if I ignore any mention of DNS your problem becomes much more clear. Based on the description minus DNS:

You have a local Exchange server. You can send Intranet messages. You can't send Internet messages to other servers like Hotmail, Yahoo, etc.

If this is true, the problem is very simple and clear: Your ISP blocks port 25, which is required for your local Exchange server to connect to other global mail servers. You require an external SMTP server configured to allow you to relay messages through it. To come back to the original question, then, the answer is yes my web host provides an SMTP server I can send messages through. Virtually any paid hosting will provide you this service (free hosts may or may not).

As far as DNS servers and Exchange goes, I should have known right from the start that couldn't be the problem. If you are running a local Exchange server on your desktop computer then Exchange will use the exact same DNS server as your web browser. Thus, if you are able to surf the Internet, which you clearly are, then your DNS servers are already working properly. You have a problem with SMTP, not DNS.

Sorry to keep stressing the issue but I must. You had me going for a long time insisting that it was a DNS problem. I took your word for it and I shouldn't have (golden rule in tech support is to assess the problem yourself, never rely on someone's opinion), which wasted a lot of time. An inability to send outbound mail via Exchange on a computer that is able to browse domains on the Internet can not possibly have anything to do with DNS problems.

[CrOtALiTo]

Perfect my own post about technical questions.

Thank you.

Maybe you're right with my issues, I'm sorry perhaps I don't knew explain you the trouble with my Server Exchange, I agree with you, because I believe my post 25 is being blocking with my Provider Internet, but really I wasted a lot of time investigating about as I can send e-mail outside of my intranet, because as you have said in my intranet I can.

But anyway outside of the intranet I can't do it, then I need to know what is the problem, really I need a solution, I don't know what I need to know with the SMPT connectors.

If you have some suggests, then please tell me.
I can give you step by step of as I installed and configured my Exchange Server into of my Windows 2003 Server Enterprice.

My sever uses an active domain controller and WINS server, DHCP Server, DNS Server between other things.

What do I need for configure my Exchange server in the SMTP Connectors then?
Absolute I need an answer now.

Best regards.

I don't see why your service provider would block port 25. It's probably being blocked at the router level. What kind of internet connection do you have, DSL?

[Tarential]

I know exactly why his ISP would block port 25: They don't want spammers with home mail servers flooding their network. Most major ISPs block port 25 (Comcast, AT&T, Cox, to name a few); though of course it wouldn't hurt to check if his router was causing problems also.

For you, Crotalito:
http://www.outlookexchange.com/artic...rticle1_p1.asp

This article describes how to make Exchange use your Internet Service Provider's mail server to relay your mail. It is meant for the Earthlink ISP but the idea is the same for any ISP mail server.

Unfortunately, some ISPs will not let you use their SMTP servers as a relay. If yours does not then you can set up Exchange to use a different port in this tutorial here:
http://blog.mbentley.net/2010/02/por...exchange-2003/

Beyond this my knowledge of the situation is minimal. I'm a Linux guy myself, and you are running Microsoft services on a Microsoft operating system. I have never set up an Exchange server myself (though I have set up sendmail and Exim, two Unix SMTP servers). I hope you can get it working though, and I wish you the best of luck.

[CrOtALiTo]

David.

I've a connection from Internet Infinitum of the company Telmex México, I have installed in my rack a modem of the same company a EchoLife HG520c as a modem only, because I had to disable to the DCHP of my modem, already I have a server what currently is working for me as DCHP server, I don't know when may is the provider internet blocking me the 25 port.

Then I don't know if I need a internet with a static IP, because my currently connection is dynamic.

I will read the link what you have lift me here in the post, I hope what I can resolve soon my trouble.
But I have the doubt as I can check if my port in this case the 25 is blocked from my provider internet.

I need to buy other device as a new router in fact?
Nonetheless I need deeper this thread, because is the first time what I try to install a server exchange in my office and with my own server.

I will let you to know a few of the configuration what I have nowadays.
I have a DCHP server, an DNS server, and WIN Server, and Exchange Server all those system are running with Windows 2003 server Enterprice.

I use a software what lets me to use a tunneling VPN virtual named Hamachi, I don't know if you know something above that software, well I need to use the hamachi for what I can connect to my server outside of my network or well in other IP range.

What do you think about?
I believe what my ISP doesn't handle the service then the question is.
How may I unlock the port twenty five from my router or provider ISP?

Absolute I need your support now.

No estoy de acuerdo. Es posible que el problema sea que el servidor SMTP remoto esté comprobando el rDNS (o incluso que haya un récord de SPF, aunque no me parece probable dado la situación). Sin embargo, eso es algo para probar después de algunas otras cosas.

Llama a atención al cliente de tu ISP.

[CrOtALiTo]

Someone know some free host where I can get a smart host for my SMPT Connector.

[pjt33]

¿Has llamado a tu ISP? ¿Qué han dicho? Es que si no puedes usar su servidor para relay, es muy improbable que dejen pasar el tráfico a cualquier host que contrates (a no ser que lo envíes por VPN, y en ese caso dudo que encuentres un host gratis).

[Tarential]

Agreed, he could be being denied since his server can't be accessed in a reverse lookup but that would only affect him with certain external servers that had it enabled. Plus, it would still not be his Exchange needing a DNS. He'd need to put himself on the actual Internet DNS servers with his own domain for example, which he said he purchased and it didn't help him.

But that's just my 2c. I'm not infallable and I certainly don't know everything about computers or the Internet, so it is a good idea to question anything I say (or anyone says). In addition to that, I'm still not 100% certain I can understand his English without inducing errors in the communication. It was easier to understand the Spanish actually Probably the same when I write in Spanish; easier to understand my English.

[CrOtALiTo]

Not I have installed two server outside of my city and I have the same problem, the e-mail doesn't go out of my intranet for instance if I can send an e-mail to Hotmail or Yahoo.

I can't my problem solely, because I told you I have installed two different server one here at my office an other outside of the City this case in Comalcalco Tabasco and both server don't able to send e-mail to other domains.

We have the Infinitum service, they are our provider service internet.
Currently I'm in meeting with my ISP provider explain them the situation what I have.
I hope have a solution soon for this trouble, because it's unbearable for me.

That makes perfect sense.
