[Dovecot] STARTTLS and inetd
by Magnus Holmgren 30 Jan '05

30 Jan '05

Hi! When running dovecot from inetd (as per the instructions on http://wiki.dovecot.org/InetdInstall) imap-login and pop3-login thinks that TLS is enabled when in fact it isn't (we're connecting to port 110 and port 143, so the --ssl parameter isn't present). The reason for that is found in login-common/main.c:main(): > if (fd != -1) > (void)client_create(fd, &ip, TRUE); I added a flag which I set when ssl_proxy_new() is successfully called (see the following diff) and it seems to work fine. Is there any reason it shouldn't? What's the reason that the code is the way it is? -- Magnus Holmgren holmgren(a)lysator.liu.se P.S.

[Dovecot] Dovecot shared folder woes
by Dave Hatton 30 Jan '05

30 Jan '05

Hi I'm new to Dovecot so please be gentle with me. I did a search through the list archives but couldn't quite work out my problem. I have Dovecot installed and running and I can connect to it from my email clients (Outlook and Evolution) ... so looking good so far. I would like to setup three types (groups?) of mail store 1. A per user - e.g. Fred, Harry, Betty. (For my purposes they all have Unix Accounts on the mail server) 2. A public store which can contain folders that may be read and written to by any user who is authenticated 3. A per group store (e.g. accounts, sales, marketing) that may be read and written to by any user who is authenticated and is in the specified group Firstly, should this be possible with Dovecot? I have tried the following dovecot.conf parameters which I thought should do the trick ... --------------------- cut ------------------------- ### this should give each user a mail store default_mail_env = maildir:/var/mail/%lu/%u/Maildir ### Create Public mail store namespace public { separator = / prefix = Public/ location = /var/mail/public inbox = no hidden = no } ### Create mail store for accounts namespace shared { separator = / prefix = Accounts/ location = /var/mail/accounts inbox = no hidden = no } ### Create mail store for sales namespace shared { separator = / prefix = Sales/ location = /var/mail/sales inbox = no hidden = no } --------------------- cut ------------------------- I then: 1. created the directories /var/mail/{public,accounts,sales} 2. chgrp each one to a group (public,accounts,sales respectively) 3. chmod 770 each one 4. created a dovecot-shared in each one - chgrp and chmod appropriately And then restarted the server Now my problem When I try to connect from a client it fails and the tcp/ip connection dies When I look in /var/log/mail I see and error 89 (which I understand is a generic error) and IMAP(fred): Failed to create storage for 'Public/' with data: /var/mail/public What and I doing wrong? TIA Daveh

[Dovecot] mutt's new mail error
by Frédéric Gobry 30 Jan '05

30 Jan '05

Hi, I use dovecot 0.99.13-3 (debian testing) in conjunction with mutt (1.5.6-20040907+2, also debian), and mutt keeps reporting new mails in my subscribed folders, even when none is available. I've seen a report from december 2003 which seems to correspond http://dovecot.org/pipermail/dovecot/2003-December/002741.html In this thread, it seems that if I don't use INDEX=MEMORY, I should not suffer from the problem. My config uses default_mail_env = maildir:~/Mail:INDEX=/var/indexes/%d/%n Do you have a hint regarding this problem ? Would a traffic dump be useful ? Thanks in advance, Frédéric -- Frédéric Gobry Infoscience DIT-KIS / EPFL Tel: +41216932288 http://people.epfl.ch/frederic.gobry

[Dovecot] Help with Outlook2003 hanging on receiving email with attachments
by John Suter 30 Jan '05

30 Jan '05

I have one user running Outlook 2003 that hangs up when receiving emails with attachments. He is connecting using POP3. It's almost as if something is timing out and closing the connection. The client is on a 1500/256 DSL connection and the server is on a 768/768 fractional T-1. I have other users that connect with Outlook/POP3 without any problems. I have done a fresh install of Windows/Outlook to make sure it's not a client machine problem. Any help or ideas are greatly appreciated.

[Dovecot] maildir and /var/spool/mail/$USER
by Rob Campbell 29 Jan '05

29 Jan '05

I was told to use dovecot because it was easier than cyrus. I just upgraded from fc1 to fc3. I am not sure what fc1 used but I think it was cyrus and it worked perfect out of the box no configurations to do. The new cyrus-imapd is not so simple so I got dovecot. I see examples saying to use mbox=~/mail:INBOX=/var/spool/mail/%u but when I try that I cannot map mail folders that reside under ~/mail. I have tried default_mail_env = maildir:~/mail:INBOX=/var/spool/mail/%u default_mail_env = mbox:~/mail:INBOX=/var/spool/mail/%u which is the setup i have now. I get this error when trying to connect via evolution error while scanning folders in "IMAP server localhost" imap command failed. invalid mask. when I use default_mail_env = maildir:~/mail:INBOX=/var/spool/mail/%u the error i get is: This store does not support subscriptions or they are not enabled. I have an Inbox Junk and Trash folder under that account. When I set up outlook as pop3 it says it connects fine but it doesn't download any mail. When I try to subscribe to folders via Outlook it says that it cannot connect.

[Dovecot] mbox slowness in dovecot-1.0-test61
by Todd Burroughs 28 Jan '05

28 Jan '05

Hi, We're trying out Dovecot to see if it's a good replacement for UW-imapd. It seems to be very slow in opening an mbox file, even after it's been indexed. (I mean way slower than UW) Here's some info on the system: Dovecot-1.0-test61 SuSE 8.1, Linux kernel 2.4 Using NFS to access mail. I've tried turning off mmap, using dotlocking, using fcntl locking (lockd, etc. are running), mbox_dirty_syncs and mbox_very_dirty_syncs. Also tried putting the cache files on local disk. Compile options where basically default. I'm accessing it with pine, using several filters which tend to do SEARCH commands. Has anyone come across this? Maybe I'm missing something obvious??? Thanks, Todd Burroughs - Hostopia todd(a)hostopia.com

[Dovecot] Moving to Dovecot
by Matt Saunders 26 Jan '05

26 Jan '05

Hi there, I'm currently running IMAP with Courier and POP3 with Solid-POP3d. I'd like to migrate IMAP and POP3 to both use Dovecot. All this works fine in testing, except for the fact that I have two types of users for legacy reasons. One type of user has a Maildir-style inbox at ~/Maildir/ The other type has a mbox-style inbox at ~/Mailbox Is it possible to make Dovecot look for both? As far as I can see I'd need default_mail_env to accept multiple names, something like this: default_mail_env = maildir:~/Maildir/ mbox:~/Mailbox ...but it doesn't, so I'm stuck. :-( By default, Dovecot would work for me if I moved all my users' ~/Mailbox files to ~/mail/inbox but I really don't want to have to do that if at all possible as that'll break other custom stuff. Does anyone have any ideas? [ Apologies if this is a FAQ - I've had a good Google around and a look at the mail archives but can't find the info. ] TIA, Matt. -- Matt Saunders http://www.yoyo.org/matts/contacts/ "This is getting very silly.

[Dovecot] dovecot Maildir issue
by Tadghe Danu 26 Jan '05

26 Jan '05

I'm working on switching a domain from a Cyrus+postfix+procmail to Dovecot+postfix+procmail (using Maildir). It works great, except one small problem. I cannot figure out what the permissions for my Maildir directories should be. Can anyone point me to a doc or just a few pointers on what the permissions of the Maildirs should be? The only way I seem to be able to make this config work is to make the Maildirs world read+write. I can't exactly roll out a config like that :). I have postfix+procmail delivering to per user Maildirs under /var/mail. The permissions on /var/mail (pulled from the Wiki) are mail:/var/mail# ls -l /var/ |grep mail drwxrwxrwt 7 root mail 4096 Jan 25 22:37 mail The user Maildirs are set as: mail:/var/mail# ls -l /var/mail/ |grep tadghe drwxr-xrwt 2 tadghe tadghe 4096 Jan 25 22:36 tadghe When I try and access a mail box I get this in the logs an 25 22:35:34 mail imap(tadghe): opendir(/var/mail/tadghe/tmp) failed: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir() failed with file /var/mail/tadghe/new: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir() failed with file /var/mail/tadghe/new: Permission denied Jan 25 22:35:34 mail imap(tadghe): opendir(/var/mail/tadghe/tmp) failed: Permission denied Tadghe

Yes I mentioned something about it in a message titled, "RE: [Dovecot] Plaintext Authentication from Localhost" On 19-Jan-2005. Seems to be a bug. At least it didn't work quite right for me. John
