[Mimedefang] mimedefang-multiplexor Out of memory message

[Rick Aliwalas]

Hello,

Just wanted to say I've had great luck w/ MIMEDefang and have found
everything I've needed over the years from the various docs and also
from this list.

That said, I just build a new mail router using a Sun X4140 and Red Hat 5.
I'm getting the following log msgs when sending a msgs locally for testing:

Aug 20 14:27:13 umailpa01 mimedefang-multiplexor[13836]: Slave 1 stderr: Out of 
memory!
Aug 20 14:27:13 umailpa01 mimedefang-multiplexor[13836]: Slave 1 ran out of 
memory -- possible DoS attack due to complex MIME?
Aug 20 14:27:13 umailpa01 mimedefang[13848]: Error from multiplexor: ERR No 
response from slave
Aug 20 14:27:13 umailpa01 mimedefang-multiplexor[13836]: Reap: slave 1 (pid 
13855) exited normally with status 1 (SLAVE DIED UNEXPECTEDLY)
Aug 20 14:27:13 umailpa01 mimedefang-multiplexor[13836]: Slave 1 resource 
usage: req=1, scans=1, user=0.794, sys=0.085, nswap=0, majflt=0, minflt=9744, 
maxrss=0, bi=0, bo=0


I've got the following in sendmail.mc:

INPUT_MAIL_FILTER(`mimedefang', `S=unix:/var/spool/MIMEDefang/mimedefang.sock, 
F=T, T=C:15m;S:5m;R:5m;E:15m')


$ mimedefang.pl -test
Filter /etc/mail/mimedefang-filter seems syntactically correct.

$ mimedefang.pl -features
MIMEDefang version 2.67
