What am I missing? DNSBL on submission port?

Hi, I _know_ I am overlooking something, and I need a clue-bat. I use postscreen on the SMTP (25) port and smptd on the submission port; the latter requires authentication via dovecot. This usually works except every now and then when sending mail, almost always from hotel networks (where I sp

how will postfix handle connections if recipient domains see ip in rbl blacklist, will it be trying agin until all ips on recipient domain is tryed ? does it make sense ? will first reject just win on dual stack ipv4 / ipv6 hostname ? i ask this since i like to know what to do with that probl

Cannot sign with DKIM on same-server web and mail

I've looked online for solutions to this problem (including postfix and sendmail documentation) but with no luck so far. I've been running a Postfix mail server for several years (currently Linux Mint 18.1 (Ubuntu 16.4) with postfix 3.1.0) and implemented SPF, DKIM and DMARC a few years ago. All

Postfix ignores smtpd_tls_security_level = encrypt ?

Hi, I need a Postfix (3.3) installation to only accept mails sent after STARTTLS, so I've set smtpd_tls_security_level = encrypt in main.cf. However, Postfix still allows sending mails withouth encryption. Do the permit_mynetworks settings in smtpd_relay_restrictions and smtpd_recipient_restrict
