I recently set up smtp-vilter 1.1.4, SpamAssassin, and ClamAv 0.75 on Fedora Core 2, I am having problems with the three programs working together. smtp-vilter seems to be working and I can send/receive mail, but clamd and spamd don't seem to be configured right, or they don't have the proper permissions. Here is a section of my mail log file with the errors:

Could there be a problem with user or group permissions on any of the directories used by smtp-vilter or clamd? What user should spamassassin be running as, and what permissions are needed on the /tmp folder?

Thanks in advance for any help with this.

Aug 19 15:33:53 pma smtp-vilter[20173]: clamd: unable to connect socket, Connection refused

clamav seems to not be able to connect. (probably to an external host for updates
then fails the scan without virus definitions, or the port could be in use already)
check the clamav documentation for which ports to allow/deny for clamav.



I usually run spamassassin as the postfix user. (but then I use postfix for my MTA)

file permissions could indeed play a part..
