Answering my own question here, but I just thought of a possible solution which seems to work: I added RELAYCLIENT=1 to the env setting in /etc/xinetd.d/submission_psa, restarted xinetd and it seems that now all messages sent via port 587 (submission) are no longer being scanned! I believe RELAYCLIENT=1 is normally set when smtp auth has succeeded, but apparently Plesk's qmail doesn't work like that. But since submission can only be used with smtp auth I guess I should be fine setting RELAYCLIENT=1 myself in that case, right? If there is no flaw in this logic, maybe I'll patch qmail-scanner to check for SUBMISSION=1 and treat those messages as being sent by a relay client, since that is an environment variable which is set by Plesk by default in the submission case. Does that sounds like I'm making sense? Could this even be a patch that you'd incorporate into qmail-scanner?
