That's neither the intent, nor my experience. When you use courier's MTA with the dns blacklist feature, the SMTP server waits for the MAIL TO: command from servers which are blacklisted, and then returns a fatal error. It is the responsibility of the server sending mail to you to inform its users that there was an error. The only time I did not see this happen correctly was with MS Exchange server. It *would* tell the sender that there was an error, but it would give its own "guess" as to what the error was, rather than returning the very helpful text of the error message from the Courier SMTP server. What mail server software are your senders using? _______________________________________________________________ Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
