hi,
[copy of message sent to philip, with extra info added and non-reverse
patch :)]
today we've tracked down a bug in the handling of queue_smtp_domains,
in exim 4.52:
the manual states that it's an expanded domainlist, but after lots of
trying today i found that i really didnt behave like one :) single
domains worked, but domainlists like
8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - >8
domainlist known_domains = [host]:[host]
queue_smtp_domains = !+known_domains
8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - >8
never seemed to produce a match, not positively nor negatively.
so we dove into the code; and we discoved a smallish bug in
transports/smtp.c for which we provide a patch here:

with this fix exim works just fine regarding queue_smtp_domains!
however, there is a snag, but i do not know whether it is related;
exim crashes sometimes with signal 11. this is from the paniclog:
2005-07-27 11:05:12 1Dxhne-00071w-JO failed to read delivery status for ...@....nl from delivery subprocess

(the dots were real mailaddresses)
no core that i could find, sorry.
i've recompiled (make clean && make), just to be sure, haven't seen
the crash again until now, but i thought i'd mention it anyway.
thanks,
Mrten.

I don't mind going nowhere, as long as it's an interesting path.
