Is this 2/5MB after encoding or before encoding of attachments? Encoding 
will increase data size about 25%.

procmail is a local delivery agent and so no, it cannot do it.

mimedefang? You have per user settings and so setting a system wide 
setting in sendmail configuration will not help and sendmail does not 
differentiate between outgoing and incoming limits so you are left with 
a milter solution and so maybe mimedefang is your best bet.

I know another centos list subscriber, Les, will swear by mimedefang.
