I'm looking at options and am curious what is faster..

Calling clamd from MIMEdefang,

or

Calling the clamav-milter from sendmail..

I am also calling mimedefang sendmail while mimedefang process's spamassasin..

Are there any downfalls to running the clam-milter vs clamd?

My sendmail config would be:

INPUT_MAIL_FILTER(`mimedefang', `S=unix:/var/spool/MIMEDefang/mimedefang.sock, F=T, T=S:3m;R:3m')dnl
INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav/clamav-milter.ctl, F=, T=S:4m;R:4m')dnl
define(`confINPUT_MAIL_FILTERS', `clamav')dnl
.....

I understand that this will process the MIMEDefang and spamassasin first and then clamav would process for virus's..

Discuss and tell me if I understand this properly..
