I clean out messages from the queue every night. Every message from
mailer-daemon and tried more than a number of times are moved to a
seperate queue. Onze a day I do a queuerun in that queue. I used to have
thousands of messages in the queue. Today the queue is only a few
hundred in size.

But occasionally I get several thousand message in the incoming queue.
That is the main problem. This stops processing all mail. I check what
unique identifier is in the file and move all those message away.

And I stop incoming mail for a few minutes. My other servers will just
accept the normal flow untill I get to them.

This will slow down the dellivery of e-mail. When you sort on host
sendmail can keep using a connection to a host. If the sort order is any
different those connections disappear from the connectionlist and have
to be re-established (almost) each time.

Will this not drive the number of processes through the roof?

I use nobody and alias that to the appropriate address (currently
/dev/null) without the need of rebuilding the configuration an
restarting sendmail.
