thanks for pointing out that the port system has it ! :)

Very interesting. Do a restart of sendmail solve the memory problem or
do you had to reboot the vps ?

this seems to be something to watch in the milter thing, memory leak
then, thanks for the info.

In fact the goal is to have a vps v2 as a mail gateway for several
others but there will be no web or local mail on it just the clamav and
spamassassin. But i agree this will slow down things as 10k+ signatures
of viruses + spam list are heavy to parse and process.

Great thanks a lot for sharing your experience here !
