Hello,
I'm getting inconsistent results with Verify Receivers - Yes (550) results.
Some emails get rejected at SMTP level as it should be, after double-bounce verification.
Some emails are accepted and then bounced resulting in NDR from Mailer-daemon.
Any ideas why some emails are accepted instead of being rejected at SMTP session?
