I setup Opensmtp on 3 Raspiberry Pis for the sole purpose of sending system messages to my email account.
All 3 were on the same LAN and it worked perfectly. I recently moved one of the Pi's offsite, so it is on a completely different net (public IP). As I mentioned in the subject line, Port 25 is blocked by the ISP. This was the smtpd.conf that was working: #OpenSMTPD table relay_secrets file:/etc/smtpd/tables/relay_secrets listen on lo \ port 587 \ hostname sbanetweb.com \ mask-src listen on socket \ mask-src action "local" relay action "myserver" relay host smtp://mcq.sbanetweb.com match mail-from "@NAS" for any action "myserver" match for local action "myserver" match for any action "myserver" How do I tweak this so it goes out 587 or 465 and sends the email. Thank you. Wayne
