Hello Sven,
I have this kind of a use case:
Postfix/Dovecot support tagged emails via a delimiter. Those emails addresses are build like {username}{delimiter-char}{tag}@example.com. This is pretty easily handled by Postfix/Dovecot.
Unfortunately, as I can see from the greylisting in Greyface, those tagged emails are not mapped to the real user which has no tag and no delimiter char.
Is it possible to have this changed in the near future?
