I have been trying for a week now to get vBulletin to play nice with my Postfix/Dovecot setup. I've thrown my hands up and have come to the mailing list for help. Yes, I've searched archives, Googled, Lycos'd, Yahoo!'d, contacted my SMTP Relay (they're useless at this point) and yes, prayed.
I'm running Ubuntu Lucid Lynx with Postfix and Dovecot installed and configured 11 different ways as per my results from various avenues of searching. I can send mail locally. I can even send mail out to yahoo and gmail accounts through a SMTP Relay I'm paying for (?). However, when I try to send out emails VIA vBulletin I get the following: postfix/smtpd[16354]: 38BEE86492: client=mydomain.com[xx.xxx.xxx.xxx], sasl_method=LOGIN, sasl_username=notelling postfix/cleanup[16359]: 38BEE86492: message-id=<20100815025837.2aff74bed...@www.mydomain.com> postfix/qmgr[15953]: 38BEE86492: from=<notell...@mydomain.com>, size=1213, nrcpt=1 (queue active) postfix/smtpd[16354]: disconnect from mydomain.com[xx.xxx.xxx.xxx] postfix/smtp[16360]: certificate verification failed for relay.dnsexit.com[64.182.102.185]:25: self-signed certificate postfix/smtp[16360]: 38BEE86492: to=<notell...@gmail.com>, relay=relay.dnsexit.com[64.182.102.185]:25, delay=2.6, delays=0.07/0.02/2.1/0.33, dsn=5.7.1, status=bounced (host relay.dnsexit.com[64.182.102.185] said: 550 5.7.1 <notell...@gmail.com>...

I've tried disabling ssl and tls all together. I've tried using one and not the other. vBulletin offers the selection of using SSL or TLS and i've tried both and none at all. Nothing is working. I am always presented with the Denied response I listed above. I have also tried generating certificates various ways in various paths. Nothing. Any help or ideas will be greatly appreciated. Thank you for your time. Eljon Curry
