...t 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...

...smtp level. It would have to "simulate" connections from external IP addresses to allow RBL etc to work and also i guess i would have to choose an "MTA style" of the sender to be simulated so that the MTA i am testing can do its thing when some tries something which fails the smtpd_*_restrictions tests. It will probably be the case that i need to "recapture" the mail at a higher detail, as an RFC compliant unit of mail in my mailbox doesn't tell me anything about how the smtp conversation went, and certainly doesn't allow me to recreate the conversation....

I need the new sleep feature (smtpd_*_restrictions) of Postfix 2.3 snapshots, but I'm using the Dovecot auth patch. The 2.2.1 patch had problems in the snapshots I tried. Fortunately the problems were very simple. rob0 at room101:~/src/mail/postfix-2.3-20050630$ patch -p1 < ~/dl/postfix-2.2.1-dovecot-auth.patch [snip] patchin...

Hello list. I have a mail server where I use Postfix+SASL. Everything works fine. Sending emails when using client (Outlook, Thunderbird or anything else) require authorization. It is OK.
