[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

Where can I find something like remote client secure dovecot best practices or, perhaps, if there is not many, if you could list major configuration/setup points. Thanks in advance

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

[Dovecot] maildir S= and W=
by Christoph Anton Mitterer 04 Nov '12

04 Nov '12

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

Re: [Dovecot] LMTP benefit vs LDA

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

Hi Javier, yes i see. Storage for now is just a 3tb sata2 hdd, so i guess that write performance is around 100 MB/s What do you think about that ?

[Dovecot] dovecot dimensioning
by mancyborg＠gmail.com 01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike
