Re: Maildrop problem

[Johannes Bunte <bunte@blackmole.de>]

I found the problem. maildrop seems to not like it when it is called 
with the user it becomes to deliver the mail. When I call it from my 
normal user account, the mail is delivered correctly. And if I change 
the user=vmail (which owns the mails and maildrop does setuid() to) to 
user=mail, then everything's alright.

I would totally agree, but unfortunately this doesn't seem to be 
possible for the reasons stated above. I will fill a bug report.

Ah, nice to know, maildrop only uses getuid(), maybe that's part of the 
problem.
