Hi everyone,

Environment: FreeBSD 14.2 / OpenSMTPD 7.6.0 and 7.7.0

Configuration:

# smtpd.conf
action "forward" lmtp "lmtp.multidomainexample.com:24" rcpt-to

Problem:
We’re getting the following error in the mail log when forwarding via LMTP:
smtp failed-command="RCPT TO:<[email protected]>" result="550 Invalid 
recipient: <[email protected]>"

This happens with multiple domains and addresses.
When switching to SMTP relaying, everything works as expected.

No such issue occurs with version 7.3.0.

Has anyone seen this before or have any ideas?

Thanks,

--
