Extensions to SMTP error codes -This would make them more like Sieve (which came afterwards, I must point out). +A number of ideas arose following a discussion on the mailing list. I record +them here so that they don't get lost. The motivations were to support the 551 +bounce code and enhanced status codes. Suggestions are to add a new ACL +feature, possibly one of: + + errorcode = 511 + control = errorcode=551 + message = 551 xxxx + +where in the last case, it's recognized by being 3 digits. In all cases, the +first digit must be "right" for the circumstance - ignore or fault if not? + +To handle ESC, perhaps a new variable called $smtp_errorcode, settable by an +option in a router when it fails, would do the trick. It could be used in any +of the above modifiers. +------------------------------------------------------------------------------ + +(355) 30-Jun-06 ?

Also the acl +for unknown smpt command could be used for other purposes, like +to dectect and react to some kiddies that send things like +http://... on the smtp port. ------------------------------------------------------------------------------ ---- HWM 353 ------------------------------------------------------------------ +--- HWM 355 ------------------------------------------------------------------ ---------------------------- End of WishList --------------------------------- |
