But what you can do is a service dovecot restart as root. I think your questions are more MTA questions then Dovecot questions. With regards, Paul van der Vlis. I should have been a bit more verbose. My present setup uses fetchmail to call mailfilter, and scans 3 different mail servers for what survives mailfilter, handing the survivors to the MTA duties of procmail. Procmail in turn uses a bunch of recipes to black hole a few, then calls Spamd, clamd to catch and or mark the mail. What survives winds up as mailfiles in /var/spool/mail. I have a bash script that uses inotifywait to watch that spool dir, and when a file has been written and closed, inotifywait exits, returning the filename to my script, which in turn sends kmail a 'get this mail' to kmail over the dbus facility. And restarts inotifywait In this manner, with fetchmail doing 3 minute sleeps between runs, mail arrives in a fairly timely manner, usually around 3 or 4 seconds processing time from the port blinks on the router to an incremented count of unread messages in whatever folder kmail stores the mail in. kmail is so broken for the version installed for Ubuntu 12.04.2 LTS that it will not even start, hence the push to get claws working in imap mode, using dovecot on this machine as the imap server so that I can then access my email from any of the other 5 machines on my local network. It a bit of a PIMA to be out in the shop, carving metal on one of my cnc'd machines and have to run back to the house to check the mail because it isn't on an imap server. I am assuming that claws-mail can do filtering to individual folders in the same manner that kmail now sorts, putting anything from dovecot.org, in the dovecot folder as one example. I'd also at this point assume I can use a cron job to synchronize the claws-mail filtering lists, but that is of course not a dovecot problem. And of course I need to keep record copies of both incoming and replied to mails like this kmail does. Which is part of the problem here because of the size of the corpus, 4.5Gb in ~/gene/Mail, and for some unk reason, ~/gene/kde/.../nepomuk/.../sopranodb and virtuosodb are using 16 gigabytes! If I don't stop, and restart kmail at about 12 hour intervals, it gets so slow its pathetic. I had to convert kmail from mailfiles to maildirs several years ago because an earlier versions math could nut handle a single mailfile above 2.1Gb. I assume that dovecot can take the incoming mail in /var/spool/mail, leaving those files zero'd out, put it into an assigned dir in the users home dir, then serve it up to that user? So what I'd like to do is have dovecot serve up everything it finds in /var/spool/mail to any claws-mail client that sends the correct password to my local ipv4 network address ###.###.###.##:143. ipv6 has not arrived in any detectable form here in West Virginia. I am also assuming that claws-mail can handle its own mail sending, or does it depend on the imaps to do that?, at this initial stage I don't know. So far, I don't even have claws-mail set to look for an imaps. I suppose that's next because I'll need a way to test dovecot as I set it up. What do I put, in which file, in /etc/dovecot/conf.d to achieve that? The wiki2 pages I know about, but are a bit short on examples to define the exact syntax IMO. Thank you.

I'd also at this point assume I can use a cron job to synchronize the claws-mail filtering lists, but that is of course not a dovecot problem. Way too much work. I use sieve with dovecot and accomplish all of the presorting, etcetera before it ever gets to claws-mail. Claws-mail does not directly respect flagged messages with color attributes, but you can easily have the sieve script add a flag for that and then have claws-mail read the flag and implement it.

Re: [Dovecot] new user questions
On Sunday 14 July 2013 12:38:21 Jerry did opine: [...] Personally, it sounds like you are trying to reinvent the wheel here. Your setup seems to be way to complicated. I would start by redesigning you whole system and eliminating procmail. It has not been touched in over a dozen years and there are far more powerful and reliable sorting methods. In your case, fetchmail combined with Postfix, Dovecot and having dovecot using a sieve script would make your life far easier. I've looked at postfix but it seems to have big treble fish-hooks all over it. Where does it fit in the 'chain of commands'? Or is this as simple as changing the MTA line in .fetchmailrc to dovecot from procmail? Interesting. Procmail used to nuke 50-100 incoming spams etc a day. But I just checked, mailfilter must be catching the huge majority of the crap, it only nuked 2 messages yesterday, so that loss is not doing to be that big a deal. So that takes care of where fetchmail hands it off to. The whole idea of removing as much of the fetching and filtering duties from kmail is because it goes to sleep when doing those things, so the user is frozen until it comes back from a mail run. Effectively making a multi-threaded system out of single threaded kmail. So I as the user sitting here, do not see, or feel, the other mail related background stuff at all. Thanks Jerry.

[Dovecot] new user questions
Greetings; Trying to follow along with the wiki2 setup instructions and thought I'd hit a snag with the first send me a mail snippet as it took several minutes to arrive, so I assume that somehow procmail was involved in the delivery and my procmail runs mail thought a whole bunch of checks before finally handing it off to a mailfile as /var/mail/gene. Then the next script seems to only try whats in my home dir, and of course doesn't find it as neither exists, yet... I assume that is because dovecot needs a kill -HUP. But I am not familiar with that, so how is it done, and as what user, me, or root, on a ubuntu 12.04.2 LTS install? Thanks.
