[Dovecot] Dovecot dies, maybe ntpdate related. I'm new to dovecot
by Xavi Montero 28 Jun '10

28 Jun '10

Hi all, my first post. After years with an old server, a couple of months ago I've installed a new one. We use IMAP. After research, I chosed dovecot. It has been running for several weeks but from one week ago or so, it suddently dies about once per day. The only change done in the server one week ago has been to install ntpdate, running once per day in cron-daily. In the cron reports, ntpdate reports a time-jump of 9 seconds each night. We did this because "apparently" we did not a "soft time drift" installing the full ntp daemon, but I start thinking the time-jump crashes dovecot. QUESTIONS: - Might this time-jump cause dovecot to die? - I don't know wehere the dovecot logs are written to. Where do I start searching? Thanks to all!

[Dovecot] "forgot my password" feature
by Mustafa Cagatayli 28 Jun '10

28 Jun '10

Hi, We have a mail server with the postfix/Squirrelmail/Dovecot(v.1.1.11) combination which we have user data on MySQL as virtual users. We have configured the SquirrelMail interface so that users can now change their own passwords. Is there any opensource solution to provide "self service password management" which would allow us to add the "I forgot my password. Lets reset it" feature which would do the authentication with the help of some random personal data or personal question/answer combination ? Regards. -- Mustafa Çağataylı BİM

Others on this list would be more help than me regarding this. From the looks of it though (after browsing the dovecot.conf file, which is well documented btw) I don't think you'd need to change a thing. We'll certainly find out if that's the case or not.

[Dovecot] Pigeonhole Managesieve issue with Dovecot 2.0
by Tim Traver 26 Jun '10

26 Jun '10

Hi all, ok, I am running version v2.0.beta6 and the latest pigeonhole build to run managesieve and the sieve delivery filters... I am getting the following response from the managesieve port when connecting : Escape character is '^]'. "IMPLEMENTATION" "Dovecot" "SIEVE" "" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." But, I think that the SIEVE line is suppose to have all of the supported sieve functions like so : "SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags notify include envelope body relational regex subaddress copy" I modified the dovecot sieve config file to try and add (although they should all be added by default), and it still comes up blank... Am I missing something? what might cause it to not broadcast the sieve implementations that it has? Thanks, Tim.

[Dovecot] auth_cache_size
by Daniel L. Miller 25 Jun '10

25 Jun '10

I was going to ask how much space I should allocate for auth_cache_size - but decided to read the wiki first. Now I'll be more specific - Wiki says about 50 bytes per passdb, and up to 200 bytes for userdb - so my arithmetic says each combined entry needs 250 bytes budgeted. Assuming that's correct, I need some clarification. Let's start small. Assume ten users, all connected - and everybody also likes looking at everybody else's mailbox. So there are ten clients, each with at least ten connections (I say at least because each folder viewed within an account is its own connection, right?). How is the auth_cache used? If I have ten user/pass combinations - is that all that is stored? Or are there connection-specific entries as well? In other words, for the above example, do I have 10 x 250 bytes yields auth_cache_size=3, or do I need 10 x 10 x 250 yields auth_cache_size=30 - or am I totally off? -- Daniel

[Dovecot] Proxy Access (Manager/Secretary) Best Practices?
by Chris Hobbs 23 Jun '10

23 Jun '10

I've mostly got our dovecot+postfix+SOGo+openldap open source groupware replacement working the way I want it to; we're replacing GroupWise in our organization and I'm thrilled to be doing it. I'm supporting about 1,000 active staff users (and another 6,000 student accounts). I've got e-mail and calendar sharing working, and it does what it says it will do, but it is (go figure) different in concept from Proxy access under GroupWise. In GroupWise, I can give my secretary proxy access to my account and she can read all of my folders, see my calendars, and send e-mail as me. To someone that receives an e-mail or appointment request from her while she's proxied to me, there's no distinction at all. Is there a way to mimic this sort of functionality with the tools I've chosen? I've figured out that I can add additional 'mail' attributes to the secretary's record, and those addresses are available as drop-down choices in the SOGo web interface, but with the secretary's name and not the manager. Any advice will be much appreciated. And many thanks to the developers involved for writing and making available such amazingly good software. Eliminating the license fees we've been paying to Novell is allowing me to save a technician that surely would have been eliminated in budget cuts this year.

[Dovecot] More Dovecot 2.0 permissions issues
by Tim Traver 22 Jun '10

22 Jun '10

Hi Timo, ok, using the latest 2.0beta6... I can't figure out the settings for the log file to have the correct permissions. When the log file is created, it is created owned by root and 0600 permissions, which doesn't allow the lda to write to it if I use different users and groups for that main config... If I then chmod the log file to 666, then everything is happy, but again, if that log file is removed and created by dovecot, it will create it back with 0600 and the lda will error and not deliver mail because of it... I was not able to find anywhere else to set the mode of the log files or the mask that is used... here is the current config : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/Maildir/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes service auth { unix_listener auth-userdb { mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] Postfix, MySQL, Dovecot LDA and alias domains
by Darek M 22 Jun '10

22 Jun '10

Hi there, I have a postfix/postfixadmin/mysql/dovecot install that was using 'virtual' for the LDA. I tried the 'dovecot' LDA to enable Sieve but ran into trouble with aliases. With domain "some-domain.com" being an alias to "somedomain.com", mail sent to *(a)somedomain.com would be delivered to the Maildir fine, but the 'dovecot' LDA tossed "unknown user" for anything sent to *(a)some-domain.com (the alias to the other domain). My dovecot.sql: driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=dovecot password=dovecot user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The problem is fairly simple: Dovecot isn't being told anything about the 'alias_domain' table that pairs alias domains with actual ones. So the question is: do I add a second "user_query" in dovecot.sql, or is there an "alias_query" directive, or similar? And does anyone have a query that would point an alias domain to the real maildir? - Darek

[Dovecot] Outlook problem
by Patric Falinder 22 Jun '10

22 Jun '10

Hi, I have some problems that every time I start Outlook and retrieve my e-mails and then later tries to do it on my iPhone for example, I get some sort of problem that I can't get the mails. I searched around on the wiki and found the "outlook-no-nuls" and "outlook-idle" options, but where am I suppose to add them? I only have "pop3_uidl_format = %08Xu%08Xv" in my "protocol pop3 {}" and it didn't work to add it to a new line there. Thanks, Patric
