Sorry, my original e-mail was quite nondescript. Consider that I have a few folders in my INBOX maildir, created with maildirmake(1) -f: Sent, Trash, Drafts, AcademicMatters, etc. Should an e-mail be sent to [email protected], it should automatically be redirected into the appropriate sub-maildir. As the AcademicMatters folder is a folder inside the `ash` maildir, there is only a single user involved, with multiple folders. > This is, I believe, an RFC so Courier is simply implementing the spec. > That's probably why there is precious little Courier reference material, it > assumes you have the RFC to hand ... It seems like sub-addressing is defined in #5233 [1]. Further discussion specific to the Sieve language is found in #5228 [2]. It seems like, to use the example in [1], an e-mail addressed to `[email protected]` is sent to the mailbox `sieve` belonging to `ken`. In my case, this would be sending mail to the `AcademicMatters` mailbox owned by `ash`. > I don't know what happens with your "-" example, but it just looks wrong to > me. In my original message, I complained that the server was throwing out an error stating that the corresponding entry could not be found in the virtual users table. It seems like the `recipient_delimiter` attribute in Postfix's main.cf can specify an arbitrary delimiter, so a plus, hyphen, or any other legal character can be used to denote the sub-address. With `recipient_delimiter = +`, e-mail sent to ash+*@suugaku.co.uk now ends up in my inbox. To inspect the text after the delimiter and move it to the correct folder accordingly is a job for Courier's `maildrop`, I suspect. > It should be looking for an AcademicMatters POP account, and then > delivering the mail to a user account called ash on the server called > AcademicMatters. I don't really understand this sentence, sorry. How can a user account called `ash` also be called `AcademicMatters` ? `AcademicMatters` is a subdirectory inside the `ash` user's inbox.

I would rather do this on the server, as I access my e-mail from various machines, many of which are not listening for mail constantly. I also dislike Thunderbird as I find it too heavy for a mail client; (Neo)Mutt has served me well for a long time. > Do post your findings, as I'm sure others would appreciate a robust (gentoo) > solution, particularly if the feature list supports cell phones (android > and/or apple cell phones) and those text/emails. I think the problem you're posing is a very different one to mine: I am only concerned with filtering e-mail to particular folders based on the address to which the mail was sent. Your problem seems to be far more generalised and large-scale.
