Hi Gilles, I don’t know how far you got with this. I have resolved the issue, cause unknown.
First, I actually had 5.4.3 and not 5.4.4. I was certain that I had upgraded. Anyway… so I simply shutdown smtpd, upgraded to 5.4.5 and booted it up again. Then rescheduling the emails worked fine much better with proper downgrade. Hopefully it was fixed by the version change (something in this area probably changed as the message formatting was a bit different). Heres a log excerpt: May 15 23:08:13 mail smtpd[5853]: smtp-out: Connecting to smtp+tls://[REDACTED]:25 (mms.[REDACTED].com) on session c1bf6e17bee0f395...
