[Dovecot] zlib error when running doveadm
by Michael Long 22 Jul '13

22 Jul '13

I manually fixed it by copying src/plugins/zlib/lib20_zlib_plugin.la to /usr/local/lib/dovecot/doveadm I do not understand why 'make install' won't do that? A bug perhaps?

[Dovecot] OT: SAN vs Flash only SAN-less VM architecture for data storage
by Charles Marcus 21 Jul '13

21 Jul '13

Hello all, I am investigating options for leveraging our companies two locations, to provide fault tolerance/redundancy for our VM infrastructure. I was looking at SAN storage options, but ran across an interesting article, and would like opinions. It sounds great, a real win-win as to cost *and* performance... We have redundant/identical hosts at each location that can fulfill the requirements discussed... http://www.storage-switzerland.com/Articles/Entries/2012/9/20_The_Benefits_… or http://tinyurl.com/khwuspo Stan, I'm especially interested in your take, considering your experience with high end SANs and VM storage environments... Thanks, -- Best regards, Charles

[Dovecot] Archiving mail
by Koenraad Lelong 18 Jul '13

18 Jul '13

Hi, I'm going to migrate my company-mailserver to new hardware. I would like to take the opportunity to archive some older mail. But I would like to have it still accessible, would this be possible with dovecot ? I mean, I would like to put that older mail from different users (I got about 50 users) on some read-only media but mount that media in the users mail-dirs. That way I will have less to backup after I backup that old mail and store it safely away. I can't convince my users to really clean up their mailboxes, so I backup more than 100GB mail while the total backup is a bit more than 300GB. Writing this I realise I could give each user a folder oldmail and symlink that to a read-only oldmail folder. Would this work ? I will have to find out how my backup-software can ignore the oldmail-folder. Thanks for any suggestions, Koenraad Lelong

[Dovecot] Password encryption type for dovecot & postfix saslauthd with mysql
by Simon 18 Jul '13

18 Jul '13

Hi There, We are using dovecot v2.2.4 (compiled from source) and postfix (yum install) on Centos 6.4. We are storing our virtual user config in mysql. Server 1 has dovecot/postfix and accepts incoming mail from our mail filter servers - this is purely for IMAP/POP services. Server 2 has postfix for our clients to send email via TLS/saslauthd. Both use the same (separate) mysql server for config. One issue is that we have a requirement to merge user / passwords for sending clients from two sources: 1) the dovecot mailbox list 2). another list. The dovecot user list is email + password. The other list is username + password. To that end we have created a view table in mysql that merges the two.. tables + view look a little like this: table: mail_users (for dovecot) email,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD table: mail_senders_other username,password username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD view: mail_senders (for postfix) username,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD I have dovecot working fine, but just need a little push in the correct direction (please) to figure out the correct settings and password encryption scheme to make the above work. Many thanks! Simon

[Dovecot] Dovecot 2.2.4 does not create home directory?
by Dmitry . 17 Jul '13

17 Jul '13

Hi, Does not create, or something I did wrong? Here http://wiki2.dovecot.org/VirtualUsers/Home it is written Home vs. mail directory Home directory shouldn't be the same as mail directory. It's possible to do that, but you might run into trouble with it sooner or later. Some problems with this are: and Ways to set up home directory The home directory is the same as the mail directory. If for example home=/var/vmail/domain/user/ mail=/var/vmail/domain/user/mail/, set: mail_home = /var/vmail/%d/%n mail_location = maildir:~/mail I think I've done it so. And yet, here http://wiki.dovecot.org/HowTo/SimpleVirtualInstall it is written Users can be added by editing this file. Dovecot automatically notices the new users immediately after they're added. It also creates their home directories when the user logs in. However, the directory is not created.

[Dovecot] Variable similar to %u but providing the username changed by a database lookup?
by Axel Luttgens 17 Jul '13

17 Jul '13

Hello, Variable %u may be used in dovecot.conf whenever the "full username" is needed. But the expansion of %u returns the username before a possible change performed thru a password or user database lookup (e.g., in the case of a SQL database, thru as "AS user" clause). Is there a variable that would expand to the changed name when used in the configuration file? TIA, Axel
