[Dovecot] Maildir and Index max size
by Emmanuel Gonzalez Carmona 02 Nov '10

02 Nov '10

Hi all, I was wondering if any of you had configured a Mailbox with >= 5GB of space with LDA indexing enabled on it. I'm trying to understand the limits to Dovecot (if there are any) regarding maildirs/indexes max size. Reading in the documentation i didn't found anything concerning this issue. Any experience with this? Emmanuel Gonzalez Carmona

[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.

[Dovecot] Linux Bootup: Dovecot Failure
by Christopher Metter 01 Nov '10

01 Nov '10

Hi there! Im using a dovecot system in combination with postfix(with dovecot lda) and ldap. Till today it ran well, but before switching to live, i did some system updates and at the reboot following message occured: Starting IMAP/POP3 mail server: dovecoUnexpected first line <localhost: timed out, nothing received> (First it says: "Starting IMAP/POP3 mail server: dovecot ", but then something fails and overrides the "t" of dovecot with "Unexpected.... ") I don't know when this error occured first, but it only goes away if i delete dovecot from autostart at bootup (by renaming dovecot-file in /etc/rc2.d/ ) No error shown in /var/log/mail.* or syslog Apart from showing this message, system is running perfectly. Users can login, receive their mail and produce new mail-traffic with postfix ;) ATM i really dont know what to do, im near switching to live status of this system and that message is annoying me. Didnt find any information on the net. Hope someone on this list can give an helpful advice Dovecot version: 1.2.15 Greetings from Germany, Christopher Metter dovecot -n: http://nopaste.info/0447cd09ba.html Boot log: http://nopaste.info/index.html

[Dovecot] [OT] dovecot appliance
by Johan Hendriks 29 Oct '10

29 Oct '10

Hello all. I am reading the mailinglist for a long time now, and there was a thread i believe called webgui or something. In this thread there was a company i believe german, that was working on a dovecot appliance with a web based gui to administrate a dovecot mail server. The problem is i did not save the URL of that company. Does anyone know which company make the appliance. Or does anyone knows a good webbased tool for dovecot. The reason is that in a windows environment, with only a few FreeBSD machine's , my collega's get frustrated if they can not use a mouse. They even want a mouse on there smartphone's :D I am doing the administration of the mail server, but when i am not there, it would be nice if they can do things them selves. thanks for your time. regards, Johan Hendriks

ALL other mail delivers perfectly but I dont know whats with crontab on this mail server. Thanks Jerrale G. SC Senior Admin

[Dovecot] Upgrading from 1.2.8 to 2.0.6: INBOX not selectable in Thubderbird (greyed and italic)
by Michele Bergonzoni 29 Oct '10

29 Oct '10

I recently upgraded from 1.2.8 to 2.0.6, I am using Maildir, and Thunderbird is showing the INBOX grayed out and in italics, and does not show new messages in it (it shows messages previously downloaded). This occurs when Thunderbird is restarted (if I upgrade dovecot, TB keeps working fine until I shut it down, and at next startup it greys out the inbox). All the subfolders of INBOX work fine. Accessing with horde+imp webmail works fine. I'm using TB 3.1.6 After some traffic capturing, The first difference I see in the IMAP exchange is the answer to 6 list "" "INBOX" Which for 1.2.8 is: LIST (\HasChildren) "." "INBOX" and for 2.0.6 is: LIST (\Noselect \HasChildren) "." "INBOX" Of course for the same user and same maildir. I enabled tb-extra-mailbox-sep in 2.0, but it doesn't appear to differ (I don't really think it should). Any help will be very much appreciated. My 1.2.8 config for the namespaces is: namespace private { prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace public { prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } And the config for 2.0.6 is the same with new syntax: namespace { type = private prefix = INBOX. inbox = yes location = maildir:~/Maildir } namespace { type = public prefix = shared. location = maildir:/usr/local/shared list = yes subscriptions = no } Regards, Michele Bergonzoni

[Dovecot] Can you POP a specific folder in Dovecot?
by Peter Reinhold 29 Oct '10

29 Oct '10

Hi all, I am in the middle of migrating from an old, Windows based mailserver, and have run into a small challenge I hope someone here can help me with. In my old setup, a user could have folders on the server, and by using his login with the mailbox appended, could pop a given folder specifically. For instance, logging in with user(a)example.com would pop INBOX, and logging in with user-folder(a)example.com would pop just that specific folder. Is it possible to do something like this in Dovecot, or is the only possible way of popping folders by using the virtual plugin?
