Well, after playing around for a while (with versions from Redhat and 
Crash-Hat), I've finally gotten ClamAV (from Redhat) to work with 
sendmail, but I'm not really happy with the solution. As it is, I have 
to manually edit sendmail.cf and add in the InputMailFilter settings. It 
seems that the INPUT_MAIL_FILTER macro for sendmail.mc is not working 
correctly. Here is part of my sendmail.mc:

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

Now from what I've figured out so far, the 'define...' line puts 
something like this into sendmail.cf:

     O InputMailFilter=clamav

And from what I've gathered from scowering through a bunch of websites, 
the 'INPUT_MAIL_FILTER...' line should output this right after the line 
above:

     Xclamav, S=local:/var/run/clamav-milter/clamav.sock, F=, T=S:4m;R:4m

...but it doesn't. This is the part I'm not happy about. If I ever make 
a change to sendmail.mc and recompile sendmail.cf, I'm going to have to 
go in and add this line again. Could somebody point out why this is not 
working as it is expected to?

Thanks,
Justin
