No-IP MTA/ SMTP Relay Issue

[Trafalger61]

I've installed Zimbra ZCS on a Ubuntu 8.04 server in my house in lombard. I have residential DSL service, so ATT blocks port 25. I have my DNS and domain registration through No-IP.com, and I'm trying to get alternate-port smtp working. I'm at my wits end. I've done this:

Outgoing SMTP Authentication - Zimbra :: Wiki

and no luck. I'm been playing around for this on/off for the last few weeks and I'm just sick of it. If someone could just point me in the right direction/offer some suggestions that would be great. I can provide any information you may need. Thanks!

What do you mean by that phrase? Is the problem sending mail or receiving it? Are you trying to relay through your ISPs SMTP servers or some other service? What errors are you seeing?

haha my bad. I'm trying to send e-mail. My ISP blocks outbound port 25. I can receive email just fine. I've gotten a host of error messages. At first it was a response from ATT"s servers saying I was blocked. I'm just curious how to setup an external mail relay or "mta?"

Does your ISP allow you to relay mail through their servers? If it does then you should be able to a) send mail without authentication or b) use authentication if they require it. If there's no authentication required you just go to the Admin UI of Zimbra and on the Global Settings/MTA tab you set the server and port that you've been given and save the changes. If authentication is required then you need to follow the instructions in the link you posted earlier. Which of those options have you tried and what were the results?

If your ISP doesn't allow relaying then you need to use an external professional service such as dyndns.org that provides a relay facility, unfortunately it's not free but it's fairly inexpensive. There are other services around if you do a search on the web.

So after you configure this what errors do you get ?
