Have you customized your filter? The example that comes with the
distribution only calls SpamAssassin if the message is 100KB or less. I
would suggest that you verify that this hasn't been changed. Also, if you
have any custom checks in your filter that open a file handle on INPUTMSG,
make sure they also check to see that INPUTMSG is less than or equal to
100KB, like this:
if (-s './INPUTMSG' <= 100*1024) {
#Do custom check here
}
Once I had a custom check I was doing that scanned INPUTMSG and I forgot to
limit it in this way. When a large message would come in the MD slave would
timeout and the message would tempfail. Once I put these limit checks in
the problem disappeared.
