Time to continue our adventure into Sieve land from yesterday.

Yesterday the result was that Sieve scripts could be put in place by the system administrator and they work. Needless to say that’s cumbersome and we want users to handle it themselves.
To avoid all possible issues with opening up FTP / DAV / whatever, the clowns at Dovecot and the ietf have decided to create a new protocol for it. Currently still a draft, but it will be an official protocol called ManageSieve. (continue reading…)

Qmail + vpopmail + Dovecot and Sieve

by on Dec.07, 2009, under Software

Let’s start with a problem description. We start out with a -working- mailer:
A pretty simple qmail/vpopmail installation with Courier IMAP and the pop3d that comes with qmail. This is administered by users with the qmailadmin frontend and allows for creation of mailboxes and forwards by postmasters. Together with spamdyke and spamassassin it works pretty well. So why change it?

The problem: First of all, Courier is a piece of shit. The various parts of it have broken in various ways over the years (authd hanging for no apparent reason or suddenly eating a ton of memory, stuff like that). Not only that, but they decided that vpopmail wasn’t worth supporting anymore, so their latest release of courier-authlib simply doesn’t handle vpopmail anymore. (don’t ask me why, can’t find any details on it).
Second of all, it would be cool to give our users the ability to create their own custom mail filters on our server. Stuff that you can do in thunderbird or through webmail, so they can setup their mailbox filters and vacation messages and whatever without me having to help them. (well…. we’ll see about that). Needless to say we could do that by giving them access to the .qmail files, but those are way out of their league. Not only that, it would be a security nightmare. So to solve that, we’re trying the Sieve disaster. I mean language… or something. (continue reading…)
