One of the features supported by postfix, and required for my setup is recipient delimiters. Using recipient delimiters, you can basically send extra information in the e-mail address, to maybe deliver the message into subfolders directly, or to run anti-spam software such as TMDA against.
Side note: if you use TMDA with what I refer to as the Challenge Response Authentication Protocol, you are a source of spam. Sending responses to users who did not send the original message is backscatter, and will get you blocked. No one wants to deal with your CRAP.
When I try to deliver such a message, I get a user unknown: [snip] Now, I am pretty sure the problem lies with the %u, expanding to user+test@mydomain, which in some way should become user@mydomain, since the latter is the actual mailbox name of the user, but: how?
Check the postfix setting recipient_delimiter.
