Oh, annoying. There was a bug in the function it used, this fixes it:

That is interesting, but I can't really think of how they could be
related.. I also did a few tests and they didn't break it either. The
only thing I can think of is that somehow the --exec-mail added a second
dovecot master process running at the same time? Did you check the
process list?

The only thing related I can think of is
http://hg.dovecot.org/dovecot-1.2/rev/0f04c7da33f1 - did you have that
patch applied? Although I couldn't reproduce the problem even with that
reverted.
