I have just installed the postfix mail server in centos 5. I have used all the instructions which were provided in this site.
The system is running ok.
But i have observed the following errors when i run
-tail -f /var/spool/maillog
ClamAV Perl module not found, did you install it? .

Actually i run the command yum install clamav perl and it was installed. I was not able to open the instructions from this website for configuring it.
Any one to help me please.

The second problem is if i enable the line /^Received:/ HOLD in the file /etc/postfix/header_cheks . Then mails will not be delivered. And if i uncomment this line then mails will be delivered.

Please anyone to help.
Ragards,

Lazaro

I would advise using the Clamav/Spamassassin install _script_ from here.

A lot less painful when it comes to the perl modules.
