I am reinstalling my ISPConfig after some idiot tried to root me and I have a few questions. When I had the system setup before I noticed I was unable to send mail from domains hosted on that machine to quite a few places. The ones that actually gave reasons was because I was trying to send mail from an IP that is part of a pool of dynamic IP's that belongs to a broadband provider. Well no crap. lol The thing is I work at an ISP (different from my internet connection) and I talked to our sysadmin and asked how to work around that without having a static IP. He said something about a trusted mailertable or something. That way I can do authenticated relaying through a different system. Now, note, I have had the same IP since I have had this service but yet it is "dynamic". I refuse to pay the $250 setup fee I would have to to get a static IP form my ISP also. So I am stuck trying to find a way to send mail. With all the people out there using ISPConfig on "residential broadband" connections there has to be a few that have it setup to handle mail properly with this issue. Any ideas?
You need an account on a trusted mailserver and relay all mails trough this server as your sysadmin told you. Have a look here for the details of the setup: http://www.howtoforge.com/postfix_relaying_through_another_mailserver
