Everything if of course restarted and the sendmail.cf is rebuilt after the
changes...
I use the following timeouts...
more /usr/share/sendmail/cf/sendmail.mc |grep sock
gives...
INPUT_MAIL_FILTER(`smtp-vilter',
`S=unix:/var/smtp-vilter/var/run/smtp-vilter.sock, F=T,
T=S:10m;R:10m;E:15m')dnl
more /etc/smtp-vilter/clamd.conf |grep timeout=
gives..
timeout=900
more /etc/clamd.conf |egrep -i 'timeout [0-9]'
gives..
ReadTimeout 900
IdleTimeout 60
If you have a really slow computer and/or a slow connection it will take more
time to process the mail which could lead to longer timeout values needed.
But if you see problems after only 45 sec you probably have something else
missconfigured or have a bug. Do you have a very old version of any involved
software ?
