Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
Hi list,

I have been using sa-exim for many years without any problems.
Unfortunately that i ran into a little snag while setting up a replacement
for my old mailserver.

The first hitch i encountered was while compiling sa-exim, the compilation
failed on amd64 and i had to add -fPIC to the BUILDCFLAGS option in the
makefile.

The problem i'm having is that if i enable the sa-exim by setting
local_scan_path in the exim config, i am unable to send mail to more than
1 recipient. As soon as i enter a second address, either in the to: or Cc:
line, i get the following error:
2009-10-07 13:49:34 1MvV1S-00049q-GY local_scan() function crashed with
signal 11 - message temporarily rejected (size 90)

Messages to a single recipient work just fine, they are scanned and
delivered (or rejected/dropped according to the spam score).

The next debug line in a message that doesn't cause local_scan to crash 
would be something like:
SA: Debug9: Did not find X-SA-Exim- in Received: from h220-21.tijo.pl 
([78.133.220.21])

exim 4.69
sa-exim 4.2.1

Seems to me that local_scan crashes in (or just before) the logic that 
looks for the X-SA-Exim- headers.
I have looked at the code, but can't find anything wrong with it.
Any help will be greatly appreciated.
