[Dovecot] Persistence of UIDs
by Jean-Daniel Beaubien 26 Jan '12

26 Jan '12

Hi everyone, I have a question concerning UIDs. How persistant are they? I am thinking about building some form of webmail specialized for some specific business purpose and I am thinking of building a sort of cache in a DB by storing the email addr, date, subject and UID for quick lookups and search of correspondance. I am doing this because I am having issue with multiple people searching thru email folders that have 100k+ emails (which is another problem in itself, searches don't seem to scale well when folder goes above 60k emails). So to come back to my question, can I store the UIDs and reuse those UIDs later on to obtain the body of the email??? Or can the UIDs change on the server and they will not be valid anymore?. My setup is: - dovecot 1.x (will migrate to 2.x soon) - maildir - everything stored on an intel 320 SSD (index and maildir folder) Thanks, -JD

Dear Sir, Thanks for your reply and I really agreed your point about 'reject mail for users over quota', but I don't want to do it if it is possible to without reject mails to deliver mails from spool to user's home directory automatically, kindly provide solution.

[Dovecot] FOSDEM
by Timo Sirainen 26 Jan '12

26 Jan '12

I'll be in FOSDEM giving a small lightning talk about Dovecot: http://fosdem.org/2012/schedule/event/dovecot I'll also be around in FOSDEM the whole time, so if you're there and want to talk to me about anything, send me an email at some point. Poll to dovecot-news list people: Do you want to see these kind of news about my upcoming talks sent to the list? Probably happens a few times/year. A simple "yes" or "no" reply to this mail privately to me is enough.

[Dovecot] Dovecot antispam plugint got an empty message
by Petr Bravenec 25 Jan '12

25 Jan '12

Few weeks ago I upgraded dovecot from 1.2 to 2.0.16 and antispam plugin to 2.0_pre20101222. Since the upgrade I'm not able to move messages to my Junk folder. In the maillog I have found this message: dspam[25060]: empty message (no data received) Message is copied from my INBOX to Junk folder, but dspam got an empty message and sent an error return code. So the moving operation is not successfull and the original message in INBOX was not deleted. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin. Can you help me, please? Petr Bravenec

[Dovecot] Imap Quota Exceeded - But Still Receiving Emails?
by Palatine Web Support 25 Jan '12

25 Jan '12

Hello I am trying to setup dovecot maildir quota, but even though it seems to be working fine, I am still receiving emails into my inbox even though I have exceeded my quota. Here is my dovecot config: plugin { quota = maildir:User Quota quota_rule2 = Trash:storage=+100M } And my SQL config file for Dovecot (dovecot-sql.conf): user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 8 AS gid, CONCAT('*:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' CONCAT('*:storage=', quota) AS quota_rule quota_rule = *:storage=3M So it picks up my set quota of 3MB but dovecot is not rejecting emails if I am over my quota. Can anyone help? Thanks. Carl

They will *always* use port 25 and nothing else. If your problem is that your Internet Service Provider is blocking port 25, you can contact them. Some ISPs will unblock port 25 on request, or might even have an online form you can fill out. If you can't get help from the ISP, you need a remailer service -- some outside proxy that accepts the mail for you and forwards connections to some different port on your computer. I don't know of any free services that do this; dyndns and others offer this for a fee, sometimes combined with spam/virus filtering. -- Noel Jones
