Hi Kai

I have no plans to add this feature. I don't like 
it for viruses, they almost always have faked 
return-path and it will cause a lot of traffic 
for the remote server that is not guilty, for the 
spam is near the same but if all the servers 
where properly configured they won't allow spam, 
so the sa-reject feature will cause them some 
traffic so the admin may configure properly his 
server or not...

I think it will be easy to modify the routine 
reject_email to pass a custom error msg, maybe 
the only modification is to change the reject 
check in the spamassassin routine, something like 
this:

from
&reject_email("We have reasons to believe this mail is SPAM",31);

to
&reject_email("We have reasons to believe this 
mail is SPAM","553 Your email is considered spam 
($sa_score spam-hits)");

The first field is passed to the logs the second 
to qmail-smtpd, but I don't now how the custom 
error patch works, so you will have to understad 
what it is needed to pass back to qmail-smtpd

For the virus you can add a call with the proper 
msg to the reject_email routine some lines after 
the line

&debug("There be a virus! ($quarantine_description)");

that is present in all the AV routines.
