Hi everyone,
Just wanted to confirm that I also encounter the same issue with bounces from
the MAILER-DAEMON now that I upgraded to OpenBSD 6.4 to 6.5 with the latest
OpenSMTPD 6.5 as you can see below:
May 26 12:20:17 mx1 smtpd[85131]: 0c12bdb4202bd21a mda delivery
evpid=8a9f8ff1c2320d8c from=<> to=<m...@mydomain.tld> rcpt=<m...@mydomain.tld>
user=vmail delay=0s result=PermFail stat=Error ("mail.lmtp: LMTP server error:
501 5.5.4 Invalid FROM: Missing domain")
May 26 12:20:17 mx1 smtpd[33901]: warn: queue: no return path!
Gilles, I was wondering if your patch for this issue will make it into the
official OpenBSD 6.5 errata/patches (https://www.openbsd.org/errata65.html)?
Best regards,
Mabi
