I would like to allow email addresses that have an unique id as prefix. For example U123456_bla@bla.tld and U654321_bla@bla.tld would be accepted and send to one users email box.
Postfix works fine on my box and I tried to add to my main.cf
recipient_canonical_maps = regexp:/etc/postfix/recipient_canonical-regexp
and defined in
But I had no luck with it. How can this be done?
Any help very very appreciated
Thanks in advance
