Reverse to the sending MTA, or the best preference MX for the address? If it's just to the sending MTA, I don't think this is a good idea. The sending MTA isn't necessarily the same MTA that handles incoming mail for that address. For example, if I send mail from [EMAIL PROTECTED] at work, my company's SMTP servers don't know anything about [EMAIL PROTECTED], so the message will be bounced by this feature. The sort of thing is very standard practice actually. On the other hand, if this Postfix feature instead queried the best preference MX for mastaler.com, which may or may not be the same as the sending MTA, I think this might be pretty useful, and would save TMDA allot of work. _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
