SquirrelMail on IspConfig: Can't send

I recently installed squirrel mail on my server that is running IspConfig. For some reason I am able to recieve emails but none of the messages I send are ever recieved. Ispconfig is using Postfix and the server is on an Ubuntu distro. I am using sendmail in SquirrelMail and when I run the configtest.php script it says that everything is working fine, but the problem still persisits.

running telnet localhost says 220 domain.com ESMTP Postfix (Ubuntu)
I have a /etc directory but no /etc/hosts directory.

Does anyone have any ideas on how to fix this? Thanks

It may help to say that I have recently moved the server from the old office which had cable to the new one which is using dsl. Also the server is working through a smoothwall firewall on the Orange interface if that helps. Here are some results in the mail log:

What I can see from here is that there is an error for antec.qes.net. antec is my server's name. But I am not sure what the previous admin used "qes.net'" for. The current domain is "qualitysiding.net"

 

Hmm, I added antec.qes.net and it is also listed in /etc/hosts file and after restarting still no luck sending. Here is the message mail.log from the last attempt to send:

I think that your provider (verizon.net) is blocking port 25

 

wow, it looks like your right. That would certainly explain why it worked on comcast and stopped working when I switched to verizon but can still recieve emails. I read up on it and it looks like a very dumb idea. Now I have to figure out how to work around it. Does anybody have any quick and easy (but not too expensive) solutions. I might be willing to pay a few bucks a month for a service but would rather have it work through my own server for free. I was given the smtp and pop server addresses from verizon but a quick test using them yielding no results for some reason. (I changed the smtp server simply to the one provided from verizon).

 

Almost there!

actually I found one that works pretty good: authsmtp.com. Its only like $24 for a year so I signed up and it seems to be working now. I have just one more question: On roundcube I can configure the smtp username and password but it looks like squirrelmail just uses the email account's username and password. Is there a way I could set the smtp info regardless of the user? Thanks
