[Dovecot] painfully slow uploads
by Mikhail Teterin 14 Oct '04

14 Oct '04

I have several mail accounts, but collect all spam e-mail in the spam mailbox on one of them. After switching to dovecot (from imap-uw) I notice a very slow speed of bulk transfers and a very high CPU utilization by the dovecot's imap process during it -- sustained 62% of my server's Pentium2 @266MHz. Never saw such effects under imap-uw... My client is KMail (despite the awfull quality of its latest release). Hope, this helps. Yours, -mi

[Dovecot] assertion failed and debugging dovecot
by Doug Luce 14 Oct '04

14 Oct '04

I'm getting this error on a particular message in my Maildir: Oct 11 21:59:48 aurora dovecot: IMAP(doug): file ostream-file.c: line 646 (_send_istream): assertion failed: (instream->v_offset <= in_size) To me, more import than the question "why is this happening" is "how can I debug this?" Attaching gdb to the running imap process doesn't give me access to the proper function names to set up breakpoints and get a stack trace. Can someone with the experience give a quick how-to on debugging functions deep in dovecot? Thanks, Doug

[Dovecot] what exactly does outlook-idle workaround?
by Jonathan Salomon 13 Oct '04

13 Oct '04

Hi, Can anyone tell me what the 'client_workarounds = outlook-idle' directive exactly does? I have enabled it in my /etc/dovecot.conf, but the problem that I think it should solve still exsits. That is that after being IDLE for more than half an hour Dovecot will disconnect Outlook but Outlook never connects back. Therefore users receive new mail, but they don't get notified unless they press send/receive. So what does the workaround do? And how can I solve the problem? Thanks! Jonathan

[Dovecot] SASL
by alan premselaar 13 Oct '04

13 Oct '04

I've been browsing the wiki and thru my mail-list archives but haven't found an answer. does/can dovecot 0.99.x support authenticating with a SASL database? I'll be setting up a new mail server for my offices using Sendmail/MIMEDefang/ClamAV/etc with dovecot as the IMAP server. I'm not familiar at all with LDAP. I know that sendmail will authenticate to a SASL database and it's fairly easy to setup. My goal is that I can support "real" users (actual user accounts) but allow their mail passwords to be different than their login passwords, and changeable via some sort of CGI interface. (I also have 2 weeks to accomplish this) any assistance is appreciated alan

[Dovecot] Does dovecot support subfolders in Outlook (and in general)
by AWC Maillists 12 Oct '04

12 Oct '04

Ok, I am playing around with dovecot and things are running relatively smoothly. I am using Outlook as that is what the client uses for Email. I can copy messages to and from the IMAP folder. I can create folders from the root directory fine. My question is this. I have folders like this: IMAPServer --Inbox --Trash --WorkToDo Now when I try and create a subfolder in "WordToDo" I get an error message "Unable to create the folder. The server responded: 'Mailbox doesn't allow inferior mailboxes' When I try to create a subfolder in "Inbox" I get an error message "Unable to create the folder. The folder 'Inbox' cannot contains subfolders..." So is this a limitation of Dovecot? Another problem with Outlook? Or do I have some configuration problem on my end? Thanks. --- Charles PS: My first impressions of dovecot are very positive. It is a much cleaner and, so far, easier to handle IMAP server than the heavyweight UW & Cyrus IMAP servers. Congrats on a impressive program.

RE: [Dovecot] Power user

Thanks for answer, The config I have is very small (for now) All of my user have an account on the machine. Very soon I plan to switch to LDAP. For my needs, a PowerUser for all domains is enough.

Not yet. But I guess I should one day add support for it. Most SASL mechanisms support it directly without a kludgy username. I'm not sure about the configuration though. For passwd-file I guess there could be just one global flag which means that the user has access to everyone's mails. For LDAP and SQL I guess the pass_filter/password_query could have a few new %vars to describe the other user. Or maybe there needs to be a separate filter/query for that case. Hmm. Do you want the poweruser to have access to all mailboxes, or just for the one domain? What passdb are you using?

[Dovecot] Detecting unused accounts
by Ben Beuchler 12 Oct '04

12 Oct '04

I'm looking for a way to figure out which accounts have not been logged in to in over n days. It occurs to me that, perhaps, the way to do this would be to look at the mtime on one of the dovecot-maintained files, like 'dovecot-uidlist'. Is there a particular file that would be modified on (almost) every login, whether it be via POP or IMAP? -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

11 Oct '04

Hi all, I am very new to dovecot and I would like to know if there is a way to configure a user with all the read/write right on all mailbox. I would like to have a power user (PowerUser) able to reach USER1 mailbox using the following login PowerUser@domain/USER1@domain and the password will be the PowerUser password. Thanks for help, Alexis

[Dovecot] Enable outlook-idle workaround.
by AWC Maillists 11 Oct '04

11 Oct '04

I just recently discovered dovecot. I am evaluating the program and several clients uses Outlook/Outlook Express. In the clients issues section of dovecot.org is says "You should enable outlook-idle workaround" Ok, maybe I am missing something very obvious here but I can not find any documentation on how to implement the outlook-idle workaround. Can anyone point me to an article or something with more details on this issue? Thanks in advance.

[Dovecot] 1.0-test47
by Timo Sirainen 11 Oct '04

11 Oct '04

http://dovecot.org/test/ Been a while since last release. Still seems there are some mbox problems, but I haven't been able to break anything for last few days. I guess it's stable enough. At least more stable than test46 which crashed quite often when expunging. - pretty much rewrote "index extension" support. it's now possible to add extensions to headers and to message records. it's possible to resize them. I'll probably use it soon to change mbox code to use 32bit offsets and automatically grow to 64bit offsets once mbox grows over 4GB (well, yes, rare, but.. :) - login_greeting and login_greeting_capability settings - auth_verbose is even more verbose - mbox fixes/optimizations - other fixes/additions
