Since you probably consider skipping spamassassin check but maybe still 
virus scan outgoing mails,
the simple solution that I am using is just something like:


sub filter_end {
.....
    if (($Features{"SpamAssassin"}) and ($RelayAddr !~ /$SafeRelay/ )) {
        if (-s "./INPUTMSG" < 200*1024) {
..... 
 spamassassin check goes here
....

This is similar to blindly accepting the mail (but it's better), because 
SA checks are those that make the delay normally.

In my case $SafeRelay is localhost + internal hosts if applicable, 
because I don't allow authenticated relay from outside.
You can simply modify my example to suite your needs - for example check 
for SMTP AUTH.
