OK, an update from my side: I never really tried anything on those retry
files but with the above information I went into /var/spool/exim4/db and
found a file called __db.retry, some .lockfiles with 0 bytes size and
some wait-* files (wait-amavis and wait-remote_smtp to be exact).
The wait-* files are 12288 bytes in size, the __db.retry one 4096. Just
for the sake of it, I shut down exim and moved __db.retry out of the
way. When I restarted exim, nothing happened at first until I tried to
deliver to my favourite greylisting server again.
End result: Exim created a file called 'retry' (not __db.retry) and
guess what size it has? Correct: 12288 bytes. My exim thread doesn't
lock up on retry any more either.
So there you have it: deleting one silly little file fixed my months old
issue (if only I had tried that before!).
Anyway, thanks for all your time and great support. Hopefully I won't
have to bother you again anytime soon.
Greetings,
Michel
