Hi, Upon further investigation what I'm seeing is if an email is sent to a non-existent address which includes the complete mail server host's name (ie. ns3.domain.com) spamdyke-qrv correctly rejects the email but if the same email is sent just to the domain name (ie. domain.com) spamdyke accepts the email and passes it on to qmail for delivery. See below for details:

Now I know from the installation notes that if you are using Plesk spamdyke-qrv is not supposed to be required as Plesk "already does recipient validation for you". I have found this statement to be false when using Plesk with qmail. Please see post at https://talk.plesk.com/threads/rejecting-email-for-unknown-addresses.339204/ Basically even though Plesk is configured to reject invalid email addresses qmail accepts the email attempt and sends a "550 sorry, no mailbox here by that name. (#5.7.17)" back to the sender. Maybe Plesk with Postfix rejects invalid email addresses but I'm not going to try that as I want to continue using spamdyke. I have spamdyke-qrv compiled/installed correctly as I can run it successfully from the command line: #spamdyke-qrv -v domain.com invalid returns no output but -vv shows UNAVAILABLE RECIPIENT #spamdyke-qrv -v domain.com valid QRV-ALLOWED(main@spamdyke-qrv.c:60): VALID ADDRESS My issue is when my server receives an email I don't see spamdyke-qrv being executed (from looking at the /var/log/maillog file). I only see spamdyke entries but no spamdyke-qrv entries so I'm assuming that is why the rejecting of invalid email addresses is still not working. My /etc/spamdyke.conf file contains among other things: reject-recipient=invalid recipient-validation-command=/usr/local/bin/spamdyke-qrv My /etc/xinetd.d/smtp_psa contains: server_args = -Rt0 /usr/local/bin/spamdyke -f /etc/spamdyke.conf /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true I'm guessing I'm missing something simple but can't see it currently. If anyone can offer a suggestion on what I'm doing wrong and what I need to do to fix this I would appreciate it.
