It was nice that Qmail kept the message in the queue that long, since the message would have not been delivered to him if I was using a MTA that gives up after five days. The problem with "there is a delay in delivering the message"-type mails is that the average user never takes the time to read those messages, and thinks that they mean that the mail has bounced. - Sam

No, the problem is that while they may be helpful if sent by a server under your control (where you can delete the message if you like) they are a nightmare if sent by remote systems where you have no chance to control them. As I said before, if you will get one every hour for a whole week (and then the message was bounced with a undelivery notice) you will surely start to hate this "feature". \Maex -- SpaceNet AG| Joseph-Dollinger-Bogen 14 | Fon: +49 (89) 32356-0 Research Development | D-80807 Muenchen| Fax: +49 (89) 32356-299 Stress is when you wake up screaming and you realize you haven't fallen asleep yet.

I know that these messages will eventually bounce but (apart from the issue of determining whether a recipient exists within a valid domain for delivery) is this "less expensive" than the more obvious 5xx response? qmail - unlike other mail "systems" - is not one big monolith program bt has many modules that work together. qmail-smtpd is receiving the messages and putting it in a queue. qmail-smtpd does not know about local users, just domains. qmail-local has all the mechanisms to deliver emails locally. I think someone (Sam?) had a modification to qmail-smtpd to mimic all of qmail-locals mechanisms to enable it to bounce messages to non local users, but that way you do all the decisions twice. For usual use (no attack with a e.g. dictionary spam) qmails way of handling things is no problem. Q2: Perhaps I have a user who makes a typo in an address. Say it is in the local-part and that the domain is valid. I have learnt tha qmail does not issue deferral notices. On the server I have worked with in the past a deferral after a few hours may result in the sender correcting the address. (Some are so stupid that a 4x4 hardwood billet but never mind!) Waiting days doesn't seem like other than a godlike retribution process for fallible beings. I personally *hate* those delay messages. Once I got one every hour for a whole week from a remote system telling me that it cannot contact the final delivery system. Really annoying and pretty useless, as there's nothing I could have done against the problems. However there is a addon module available at http://www.qmail.org/ that IMHO does what you want.

Really annoying and pretty useless, as there's nothing I could have done against the problems. The time I liked it was when I was sending a quote and had misunderstood the destination address (or mistyped it, I forget which) and so two things happened: First I had a chance to resend so that my customer did not have to wait 5 days and maybe I would have lost him. Secondly I had a number of re-inforcement messages reminding me to get it right first time! However there is a addon module available at http://www.qmail.org/ that IMHO does what you want. Search for delayed-mail notifier on qmails website. Thanks for that pointer. I didn't go looking because I just knew it wasn't a qmail thing to do! Back to being a lurking sponge..

I didn't go looking because I just knew it wasn't a qmail thing to do! but do be careful with that code - it will attempt to send notifications to many mails that you might not want to send notifications to (mailing lists, bounces, etc.) On the subject of notifications, it's becoming more of a problem because of "similar" domains - you should have typed "[EMAIL PROTECTED]" and instead type "[EMAIL PROTECTED]". The latter doesn't even accept mail deliveries, so it hangs around in the queue for too long. In the case of typing "[EMAIL PROTECTED]" instead of "[EMAIL PROTECTED]", qmail as the sender *will* bounce the mail quickly, if is told there is no such remote mailbox "jo". Similarly as the receiver, qmail *will* send a bounce message telling the sender that there is no such mailbox "jo." Your original email implied that it didn't (not sure which of those two cases you were specifically referring to), and that puzzles me. James.
