There are many places where this tactic will cause the sending MTA to be immediately blacklisted locally - and a few places that will escalate a complaint back to both your upstream and to various DNSBLs. Any 5xx error means "quit trying, give up" - that's what "permanent error" means. MTA admins tend to get upset when you ignore the "permanent" part of "permanent error" and keep pecking away at their servers. If you feel you've encountered a misconfigured server setup, then you need to contact the MTA admin (either by email to postmaster / abuse, or offline - such as by phone) and point out the misconfiguration. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
