I searched every logfile I could find, but without any results :( How does it usually work? The mail is send by another server and on my server, does postfix receive the email or is it dovecots job? Who puts the mail into that mail directory? I guess it's postfix?
If you are administering an e-mail server, this is stuff you are supposed to know.
If it is a large enough installation to warrant /domain/localpart/ naming and MySQL user database, then you really should be fully up to speed on this stuff.
In general, your MTA (Postfix in your case) usually receives e-mail by SMTP usually via TCP on port 25.
Depending on your MTA configuration it may deliver the mail directly to a file itself, or it may send it to another program by means of a socket, or by piping the message into another program invoked on a per-message basis.
To progress your issue further, you probably need to work out how you have Postfix configured.
