I've googled around and although I get a lot of hits about postfix smarthost authentication with ssl, I can not find out how to actually accomplish the task. I've read through smatterings of postings from Neophasis and the like searching for just the syntax and what file (I assume it's main.cf) I should be using; however, any smtpd_ lines I have tried result in postfix hanging and refusing to deliver mail. I could simply cease using smarthost, but my ip address is dynamic (yes I know stop yelling at me I'm poor right now) so mail bounces to some domains if I don't use smarthost. The server I'm running postfix on is CentOS 4 (fully updated). Postfix version is 2.2.10-1.1.el4 (from rpm -qa). I have not had sufficient downtime to upgrade to CentOS 5. Should I do that?
