[Dovecot] Multiple Patitions with with mdbox
by Peer Heinlein 09 Nov '11

09 Nov '11

Having > 10 TByte mailstore filesystem-checks takes too much time. At the moment we have four different partitions, but I don't like to set symlinks or LDAP-flags to sort customers and their domains to there individual mount-point. I'd like to work with mdbox:/mail/%d/%n to calculate the path automatically. How do you handle >> 10 TB mailstore? I'm very interested in the feature "alternative mailstore" with mdbox, because that makes it very easy to use at least TWO filesystems without any tricky configuration. I think I'd love to have <n> alternative mailstores. Why does dbox doesn't look for its m.*-files in more then two directorys? Sure, looking in 4 directorys would lead to four disc operations, but maybe it could be very helpful.

[Dovecot] Dovecot alias and mailbox problem
by Jeroen Grusewski 08 Nov '11

08 Nov '11

Hi All, My Postfix / Dovecot / MySQL is running fine but I have the following issue: When I create the following mailboxes test(a)example.com and test1(a)example.com it is working fine. I can create an alias test2(a)examples.com => test1(a)example.com that is also working without a problem, only when I create test(a)example.com => test1(a)example.com email is only delivered to test1@.... instead to both test@.... and test1@.... I believe it is properly just a setting but please help me out here ! Let me know if you need any more information before I post configs etc. Best regards, Jeroen

[Dovecot] dsync and zlib
by Peer Heinlein 08 Nov '11

08 Nov '11

Will dsync also use zlib-compression when copying mails from one side to another? Wouldn't this be a good way to compress existing mails? http://wiki2.dovecot.org/Plugins/Zlib says, there's no way to do that. But dsync should respect the zlib-Plugin...

[Dovecot] Failing to share folders when listescape is enabled (2.0.14)
by mailing lists 08 Nov '11

08 Nov '11

Hello, How I can share a folder with dots when the listescape plugin is enabled? In this example user001 is sharing two foders named "docs-abc" and "docs-a.b.c" to user002. The first folder (without dots) is seen by user002 but the second is not found by dovecot because it search a system folder named ".docs-a.b.c" but the system folder is ".docs-a\2eb\2ec" Nov 8 11:03:52 imap2 dovecot: imap(user002): Debug: acl vfile: file /var/virtual-maildir/user001/.docs-a.b.c/dovecot-acl not found drwx------ 2 vmail vmail 4096 2011-11-08 10:54 cur drwx------ 5 vmail vmail 4096 2011-11-08 10:57 .docs-a\2eb\2ec drwx------ 5 vmail vmail 4096 2011-11-08 10:57 .docs-abc -rw------- 1 vmail vmail 20 2011-11-08 10:57 dovecot-acl-list -rw------- 1 vmail vmail 248 2011-11-08 10:55 dovecot.index.log -rw------- 1 vmail vmail 96 2011-11-08 10:54 dovecot.mailbox.log -rw------- 1 vmail vmail 51 2011-11-08 10:55 dovecot-uidlist -rw------- 1 vmail vmail 8 2011-11-08 10:57 dovecot-uidvalidity -r--r--r-- 1 vmail vmail 0 2011-11-08 10:54 dovecot-uidvalidity.4eb8fc5b drwx------ 5 vmail vmail 4096 2011-11-08 10:57 .Drafts -rw------- 1 vmail vmail 15 2011-11-08 10:54 maildirsize drwx------ 2 vmail vmail 4096 2011-11-08 10:54 new drwx------ 5 vmail vmail 4096 2011-11-08 10:54 .Sent drwx------ 5 vmail vmail 4096 2011-11-08 10:54 .Spam -rw------- 1 vmail vmail 23 2011-11-08 10:54 subscriptions drwx------ 2 vmail vmail 4096 2011-11-08 10:54 tmp drwx------ 5 vmail vmail 4096 2011-11-08 10:54 .Trash # cat /var/virtual-maildir/user001/subscriptions Trash Sent Drafts Spam docs-abc docs-a\2eb\2ec # telnet localhost 143 Trying ::1...

[Dovecot] Attachements with SIS : shauld all the same files share the same inode ?
by Yann Dupont 08 Nov '11

08 Nov '11

Hello. I configured SIS , and all seems to work well, but I noticed something strange : For exemple, this attachement : 6e/2d# ls -al 6e2df299* | sort -n 104 instance of -rw------- 104 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-ffd0d1xxxx The files are hardlinked, so it seems ok, but I also see 9 others files in the same directory : -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-0519df2a94fc9a4e1f4100008a6b99b6 -rw------- 1 vmail vmail 346584 16 oct. 17:47 6e2df299fa96daec9b4735d07c494046429be4d6-1790b92994fc9a4e1a4100008a6b99b6 as you can see, same prefix, If I compare them with diff, they are all the same files. ls -i show that 104 have the same inode, as expected, and the 9 remaining files have different inodes. I expected all the files share the same inodes. Is there something wrong here ? My setup is debian squeeze + auto packages from http://xi.rename-it.nl/debian/ dovecot is 2:2.0.15-0~auto+21 thanks, -- Yann Dupont - Service IRTS, DSI Université de Nantes Tel : 02.53.48.49.20 - Mail/Jabber : Yann.Dupont(a)univ-nantes.fr

[Dovecot] How to define ldap connection idle
by Aliet Santiesteban Sifontes 08 Nov '11

08 Nov '11

I'm having a problem with dovecot ldap connection when ldap server is in another firewall zone, firewall kills the ldap connection after a determined period of inactivity, this is good from the firewall point of view but is bad for dovecot because it never knows the connections has been dropped, this creates longs timeouts in dovecot and finally it reconnects, meanwhile many users fails to authenticate, I have seen this kind of post in the list for a while but can't find a solution for it, so my question is how to define a idle ldap time in dovecot so it can reconnect before the firewall has dropped the connection or just close the connection under inactivity so when a user authenticate doesn't fails for a while until dovecot detects that the connection has hanged. Is this a feature request or there is already a configuration for this??? Thank's in advance and congrats tu Timo for this great app.

[Dovecot] Accessing a strange mailbox

I have a user who has a mailbox called: A----->B It seemed to work in courier fine, they managed to create it, and there are mails in it. However, dovecot is not letting the user access it, the IMAP server gives an error. I tried to rename it but I would also get an error: # doveadm mailbox rename A-----\>B AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # doveadm mailbox rename A----->B AtoB doveadm(root): Error: Can't rename mailbox A----- to AtoB: Mailbox doesn't exist: A----- # doveadm mailbox rename 'A----->B' AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # doveadm mailbox rename "A----->B" AtoB doveadm(root): Error: Can't rename mailbox A----->B to AtoB: Mailbox doesn't exist: A----->B # How can I deal with this mailbox (using mdbox here)?
