Default Outgoing Mail Problems

I followed the tutorial The Perfect Server - Ubuntu 10.04 [ISPConfig 3] verbatim and I'm pleased to say the process has been far less painful than I imagined (first time Linux server). I have been developing my website locally for a few days now and now that my domain name is done propagating and pointing to my server, I want to make sure I get everything ironed out.

I can receive emails fine, but I am unable to send any emails via squirrelmail. During the tutorial, I told configured squirrelmail to use courier. My ISP is not blocking ports 25, 110, 143 and these ports are properly opened in my router.

I have an email domain set up with the following settings:
Server: server1.domain.tld
Domain: domain.tld
Spamfilter: Not enabled

I have a mailbox set up with the following settings:
Spamfilter: Not enabled
Enable Receiving [yes]

Also, far as control panels go, I'm used to CPanel where it spells out the correct IMAP / POP3 login information for you. It is my goal to be able to access my email via IMAP, but I don't know what the correct settings would be for my particular [default] case (e.g. Incoming IMAP Server, Outgoing SMTP Server, etc). I'm also interested in figuring out how to enable TLS.

One last issue worth mentioning is the fact that I cannot access squirrelmail via domain.tld/webmail, so for testing purposes I have just been using 192.168.x.x/webmail. Using the former brings me to a ISPConfig 404 page.

Thanks in advance! Excellent site and guides.

Update: I have tried sending to Gmail accounts and just tried a Hotmail account. Gmail didn't give me any feedback so I figured my server just wasn't sending...


I got a "Undelivered Mail Returned to Sender" email from Hotmail:

Action: failed
Status: 5.0.0
Remote-MTA: dns; mx4.hotmail.com
Diagnostic-Code: smtp; 550 DY-001 Mail rejected by Windows Live Hotmail for
policy reasons. We generally do not accept email from dynamic IP's as they
are not typically used to deliver unauthenticated SMTP e-mail to an
Internet mail server. http://www.spamhaus.org maintains lists of dynamic
and residential IP addresses. If you are not an email/network admin please
contact your E-mail/Internet Service Provider for help. Email/network
admins, please visit http://postmaster.live.com for email delivery
information and support
Cool, so my outgoing mail is sending, but it's being blocked. How do I fix this?

Also, I just figured out that I can connect to my email via IMAP by just using my server's internal IP address (192.168.x.x) or by simply entering domain.tld as my Incoming IMAP Server. Also, I can send emails (to myself anyway) by using domain.tld as my Outgoing SMTP Server.

Nevermind, I got it working. Possible solutions:

1. Configure outgoing mail to send over port 587
2. Remove your IP from the Spamhaus PBL

I did both. Outgoing emails get delivered perfectly now.
