Just to register interest, but at some point I will need to consider writing a plugin or similar to achieve exactly this.
Situation is that several of our competitors offer such a feature, ie known pool of users on dialup or intermittently connected systems, provide an alert back to the sender when your email has been "accessed/downloaded" by the remote user.
My dentist used a service that claimed to provide a read-notification.
It was just an embedded web-bug in the email that I could choose to display or not ... if the client doesn't want to cooperate, you can't tell when the person read it. All you could do is tell when a client downloaded it from dovecot...which doesn't say much for clients that are left on 24/7...
Please folks - don't argue with me - I'm the wrong person! The recipient who is receiving these emails, ie the person being "bugged" is demanding that they are "buggable". If they demand it and it's a requirement for providing them service then I have to give it to them if I want the business.
The users are on satellite dialup and barely have enough bandwidth to download a few KB of emails, they certainly can't trigger web bugs to trigger read receipts.
Look, I can argue against the idea easily, personally my objection is mail loops, but the point is that the customer demands it, and at present that prevents me bidding for certain types of business... Basically the customer just wants to repro what they got with Exchange
Cheers for ideas though!

Hi Ed, you can have dsn http://www.postfix.org/DSN_README.html
you can have mdn http://en.wikipedia.org/wiki/Return_receipt
so this is internet (smtp ) standards and has nearly nothing to do with imap/dovecot
also whatever solution you use there is no way to find out if a user has read a mail unless you asked him in person ( and then you might find out if the recipient has understood what he had read *g)
the maximum you may reach is get notice if a mail has tec side reached the recipient, the user must not accept your wish to notice you if he opens the mail ( which also would not mean he has read the mail )
this is with internet mail, by intranet mail systems ( which means the recipient is on the same mail system and storage) typical for company mail sites with exchange and/or notes etc you have a dediacted client i.e outlook for exchange , so here its possible to implement inside actions whatever tec of this system is able to do.
But as soon as you mail to internet, this features may get useless , cause you never know what tec is used on the recipient side so nobody may invest time in create useless internet standards
however youre free to code or pay someone to code for you what you want specially for your wanted feature. But i see no real relate to dovecot, cause mail is recent sent via smtp
Dont compare mail systems this way, they are totally different however they do imap/pop3/smtp specially with echange some stuff will only work with outlook and active directory
