I'm running the same kind of setup, including custom matchers and mailets to record the status of individual emails in a database. I do not tinker with the return path, but use different addresses in the envelope for the from ande reply-to. I've seen some things that I did not expect, such as out-of-office messages that are sent to the from address. > PPS: Regarding categorizing bounces, I'm not doing that right now > (mainly due to lack of time).

I've made an attempt to do exactly the same thing, but I'm not happy with the results so far. What I tried to do was to look for an SMTP status code that indicates the persistence of the failure to deliver the message so I can discriminate between transient and permanent failures. I'm using all the text parts of a message to look for the SMTP status. My experience so far is that a lot of bounces do not contain an SMTP status that can be used for such purposes, but maybe I'm looking at the wrong things. -- Jeroen --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
