...vel. 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. Is anyone buil...

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] patching file src/smt...

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.

I documented my own setup as I went (below) so something based on this to give an idea: http://forums.pcper.com/showthread.php?t=448351 ...and if that goes down well, then maybe a section on anti-spam settings (_restrictions) available in postfix to complement the recent postgrey greylisting guide. As always, I'd welcome input/comments from those more experienced! Regards, Ned

...SPF, DKIM and DMARC work fine, now I'd like to limit the spam tsunami. Besides the official Postfix documentation, I've read a few articles about Postfix spam restrictions, namely these : https://www.linuxbabe.com/mail-server/block-email-spam-postfix https://wiki.centos.org/HowTos/postfix_restrictions After some experimenting, here's what I currently have on my test server: --8<----- /etc/postfix/main.cf ----------------------------- ... smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, check_helo_access hash:/etc/postfix/helo_access...
