I'm trying to send a set of log messages to an email address and I'm getting:
Final-Recipient: rfc822; email@example.com
Remote-MTA: dns; relay.plus.net
Diagnostic-Code: smtp; 552 dJqt1u0020mutzo01Jqvm6 message rejected due to spam
or virus. If you believe this is in error please login to your portal or
contact your ISP support team.
Is this PN's email server rejecting it or the target host?
