When an email is evaluated as spam and in turn is rejected during the SMTP
dialog, is it reasonable to show in the SMTP response the result of the spam
evaluation or not?

We include the complete SpamAssassin report in our 550 responses. I don't
buy the security argument, since spammers (or rather their software)
alredy know how to check their messages with SpamAssassin before letting
rip.

Some MTAs only make one line of the rejection available in their logs, or
don't make it easy to get the rest.

If you're returning multiline responses, make sure that the first line has
the critical data, and use the remainder for additional info.
