Hi there,
Can anyone explain why I have > 150k messages on my queue, most of which
are failed bounces, e.g:

*** Frozen (delivery error message)
...even though I have
ignore_bounce_errors_after = 8h
timeout_frozen_after = 5d
In my Exim config.
Both of these messages are clearly > 5d old, for a start.
Admittedly, I may have changed those settings since the messages were
queued, but surely those settings are read by each queue runner?
This is causing something of a problem, as there's now so much on the
queue that it's interfering with local delivery to the point that I had
to set queue_smtp_domains = * so that local deliverys would take
preference (this server is only really supposed to be accepting mail for
pop3 users) but that's a but sub-optimal as it means that anything
that's being redirected in /etc/aliases is being swallowed.
FWIW, I also switched to split_spool_directory in the hope it'd drop the
system load a bit and process it all a bit quicker.
The machine should be beefy enough, it's a dual P3/800 with 786Mb RAM
and the maildirs and spool are held on separate ATA100 disks. Load
average is insanely variable, but having jiggered it all about it seems
to have settled a bit.
Anyone shed any light?
