I am not sure whether this is a good idea.

in the fetchmail case, postcommand "/usr/sbin/exim4 -q" solves this
issue nicely by starting a queue runner after finishing mail
collection. I find this much more elegant.

I'd rather err to the safe side.

A longer elaboration about this issue is mentioned on
http://wiki.debian.org/PkgExim4UserFAQ#head-bf42ef41ae163a7ba6d076540c7bb428a70ca04e,
headline "Exim stops delivery after ten messages are received". I'd
like to hear more arguments from both sides.

Greetings
Marc, apologizing for the long time to reply.
