I have been seeing a LOT of SMTP relays used lately and after looking through the logs, it appears that MailEnable is bouncing emails that should be discarded. I have checked that all domains are set on discard, however, I see emails come in, then go right back out. Sometimes immediately, sometimes it waits a few minutes. Again, ALL domains are set to discard non-deliverable emails. Anyone shed any light on this problem or offer any help? In advance, thanks.
