I am using Nethserver 7.9.2009 version with AD intergration. Am however not able to send mail to groups even though they appear visible on the server with automatic alias for groups enabled.
They keep bouncing with this error below:-
- 550 5.1.1 <firstname.lastname@example.org>: Recipient address rejected: undeliverable address: host email@example.com[/var/run/dovecot/lmtp] said: 550 5.1.1 <firstname.lastname@example.org> User doesn’t exist: email@example.com (in reply to RCPT TO command)
Any idea on how to make it work?
