Hello Just FYI,
After simple putting this line into postfix's main.cf: recipient_delimiter = + And reload postfix, the plus alias address should work. I am using dovecot LMTP as delivery agent. Nothing changes to dovecot configuration. Here are the versions: Postfix 3.6.4 Dovecot 2.3.16 OS Ubuntu 22.04 Thank you very much for all helps. regards Tom _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-le...@dovecot.org
