A little note there: I recently sent a message to a misconfigured domain
(their MX was pointing to an invalid hostname that didn't resolve) and
exim got into the same loop, so it doesn't only affect 451 failures but
also other messages deliveries that need to be retried.

Note that I get those for mails that are not stuck and it might be
normal as mail that comes in gets forwarded through Amavis and Spamcop
here.
The stuck message doesn't seem to appear in the log at all any more,
unless I try to remove it through eximon in which case I get:
2006-04-20 21:06:35 1FWeOO-000396-DP Spool file is locked (another
process is handling this message)
until I kill the hanging process with -9.

I already upgraded (being that it entered etch I got it a few days ago)
but the problem persists.

Certainly, I have attached the config file template to this message
(hope it goes through OK). The mentioned alias files just have the format:
aliasname: realusername
aliasname2: realusername2
What do you mean with how often I start queue runners? I normally don't
touch exim (except for running mailq, to see whether a message got
stuck, and killing processes with -9).
My /etc/default/exim4 states:
QUEUERUNNER='combined'
QUEUEINTERVAL='30m'
COMMONOPTIONS=''
QUEUERUNNEROPTIONS=''
QFLAGS=''
SMTPLISTENEROPTIONS=''
Hope that helps, let me know if I can help debug this further with my
limited skills and thanks for the support.
