[Dovecot] Deliver bounces messages if can't write to logs
by Francisco Reyes 04 Dec '06

04 Dec '06

I am new to using Dovecot's LDA deliver. One particular item which I think may be improved.. If one uses logs instead of syslog and if Dovecot/Deliver can't write to the logs, mail is bounced. In contrast if it can't connect to the authentication socket auth-master, it defers. Shouldn't mail be deferred if access to the log files fails due to rights? Doesn defer makes more sense than to bounce in this case? In all likelihood it was postfix that bounced/deferred, but I believe it has to do with what response postfix got from deliver.

[Dovecot] Enabling different quota limits for different users for /etc/passwd as userdatabase on FC3
by ankush grover 04 Dec '06

04 Dec '06

hey friends, I am running my company's mail server on FC3 which comprises of Postfix + Dovecot + MailScanner + Clamav + Squirrelmail + MailWatch + Spamassassin. I am using Dovecot 0.99.13-3 version on FC3 and I want to implement Quota limits for the users. I am using userdatabase as /etc/passwd file (auth_userdb = passwd ) and password database as pam(auth_passdb = pam) for dovecot. I read the documentation of dovecot but the quota example for /etc/passwd is missing. I want to have different quota limits for different users for example Quota limitation will depend upon the users, well there will be a global quota limit which will takes place if there is no limit specified for that particular user. Can anybody guide me how to configure quota's for different users in dovecot for /etc/passwd as userdatabase and pam as password database. Please let me know if you need any further inputs. Thanks & Regards Ankush Grover

[Dovecot] Protecting folders

Hi. Is it possible to prevent certain folders from being deleted via IMAP using Dovecot? I don't want to write protect the folders, just prevent people from deleting their Junk, Trash, Drafts, etc. -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] / and . in folder names
by Magnus Holmgren 04 Dec '06

04 Dec '06

Right now, trying to create folders with "/" or "." in their name can yield strange results, because Dovecot simply turns every occurrence of the current folder hierarchy separator in a folder name given by the client into a "." (or so it seems). If the folder separator isn't ".", clients can try to create folders with names containing ".", and Dovecot will convert those "." back to the folder separator on listing. It will look like there is an intermediate folder, but Dovecot is unaware of it. If the folder separator isn't "/", clients can try to create folders with names containing "/", which will simply fail. Judging from to http://www.courier-mta.org/?maildir.html, Courier encodes "." and "/" in the names of the directories the folders are stored as on disk. This means that that of "." and "/" that isn't the folder separator can be used in folder names, but it also means that Dovecot has to be able to perform the recoding. Has any thought been given to this? -- Magnus Holmgren holmgren(a)lysator.liu.se (No Cc of list mail needed, thanks) "Exim is better at being younger, whereas sendmail is better for Scrabble (50 point bonus for clearing your rack)" -- Dave Evans

[Dovecot] Evolution: DATA command failed: Requested mail action aborted: exceeded storage allocation.
by Rob Frohne 03 Dec '06

03 Dec '06

Hi Everyone, I have been recently getting these errors in Evolution 2.6.1. I think it is a client issue, as I don't see them using Thunderbird on the same machine (though I get a lot of "disconnected from servers" from Thunderbird. On Evolution 2.8.1 on another machine I haven't noticed these issues. DATA command failed: Requested mail action aborted: exceeded storage allocation. It seems that it happens when my sent messages are attempted to be stored on my IMAP sent folder on the server (running dovecot 1rc15, and OS X. I can't find any hints in the mail.log on the server or the system.log on the server, or the system.log on the client. Any idea on how to troubleshoot this? Thanks, Rob -- Rob Frohne, Ph.D., P.E.

[Dovecot] Deliver Root Setuid
by Láďa 03 Dec '06

03 Dec '06

Hi, I just configured my Postfix installation to deliver via Dovecot LDA. But because I use separate uids for virtual domains I had to set deliver to be setuid root. Altough I find this as frequent answer to this problem with deliver LDA I am not a 100% sure - basically because I try to avoid root setuids as much as I can. What should be better solution - to have all mailboxes with one owner or this setuid binary? My main reason for separate uids was filesystem quotas for whole domain. But my mail partition resides on XFS so I can do the same with directory quotas and I also noticed changes in quotas which should be also per domain in some next release or with patch. Thanks for any advice and also thanks for all great work on Dovecot. Láďa

[Dovecot] Too many open files
by bofh list 03 Dec '06

dovecot: Nov 08 04:04:23 Error: IMAP(user): open() failed with file mailstore/user/Maildir/.Alerts/dovecot.index.log.2: Too many open files dovecot: Nov 08 04:04:23 Error: IMAP(user): open(mailstore/user/Maildir/.Alerts/tmp/1162976663.P4853Q1817.server) failed: Too many open files dovecot: Nov 08 04:04:23 Error: IMAP(user): open() failed with file mailstore/user/Maildir/dovecot.index.tmp: Too many open files Seeing this with both 1.0beta9 and 1.0rc12 This occured when a user was not using the client, however the client(Thunderbird) filtering mechanism was active as their client is left on 24x7. Do we really need to increase individual user maxfiles to >1024 ? Dovecot is set to 31768 so it is definately the user process here. Anything I can tweak in dovecot.conf to prevent this? Thanks!
