I have my own email server, and I'd like to be able to use dynamic email address tagging. I added the recipient_delimiter = +-
directive to my config and restarted postfix, but now if I email bob+sometaghere@starbeamrainbowlabs.com
for example, the email will be bounced with the error "Unknown User". If I email unknownuser@starbeamrainbowlabs.com
, the email is delivered to the webmaster
account as expected.
Here's my postfix config:
## These are all default Postfix settings that we won't change

From /etc/postfix/master.cf
, I have this defining Dovecot:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver
-f ${sender} -d ${recipient}
I also have definitions for ifmail
, bsmtp
, scalemail-backend
, mailman
, uucp
, scache
, maildrop
, and a bunnch of others, but I'm not entirely sure what they all do.
Does anyone know what is going on here and how I can fix it please?
I'm using virtual mailboxes.
