Thank you for your response.
I have tried this, incrementing C,S,R, and E (you didn't really say
which), and wound up increasing all of the to 15m. I also changed my
clamd.conf to 900 seconds as you suggested.
Same thing happens. It quits after only about 45 seconds or so, stating
clamd is not available.
Here is what I did to my sendmail.cf:
--------------------------------------------------------------
INPUT_MAIL_FILTER(`smtp-vilter',`S=unix:/var/smtp-vilter/smtp-vilter.sock,F=T,
T
=S:15m;C15m;R:15m;E:15m')dnl
------------------------------------------------------------
I do think you are right -- this is probably smtp-vilter being impatient
with clamd, but I have incremented the timeouts... what else can I do?
I can find no timeout directive for smtp-vilter...
I'm getting desperate here...
Any other ideas?
Thanks.
Chris
