A week or so ago somebody flattered me by saying "MTA writers are gods".
If that's true, I must be a pretty minor god, because I'm unable to fix
a problem on the basis of such a small amount of information as "there
was a crash".
If you want me to investigate this, you'll have to send me a lot more
information. Preferably log extracts, and even better, debug output from
a delivery that crashes.
On the other hand, perhaps I can exhibit a little god-like omniscience
by asking "Does your configuration or filter file make any references to
headers such as $h_to:?" If so, the following fix, which is in the
forthcoming 4.10 release, may be relevant:
11. A reference to any header line that contains addresses (e.g. $h_to:) caused
a crash if the header was empty. Change 46 for 4.05 introduced this bug.
There is a patch for 4.05. I can't remember if I posted it before, but
as it's pretty small, I'll repost it below.
