Troubleshooting Spam and Virus Filtering

Clam AV

I kept getting lockup errors in my maillog from ClamAV. the errors read:

Milter (clamav): timeout before data read
Milter (clamav): to error state

I still do not have a fix for this. For now I have disabled the Clam-AV Milter. To do this go back to Step 1 when setting up your Spam Filtering on your Sendmail Server and just commetn out (or delete) the Clam-AV Line. then Rebuild.

Step 1: Change the Config line for Clam-AV to:

dnl# INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav-milter/clamav.sock, F=T, T=S:4m;R:4m')

Step 2: Then you must rebuild your Sendmail file:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

Step 3: Restart Sendmail

SMTPAUTH

You might not get any response when using SMTPAUTH. Remember, SMTP uses TCP/IP Port 25, SMTPAUTH uses port 465 so open that in your firewall.

Sendmail Configuration File

Here is a copy of a sample Sendmail configuration file for your reference.
