[Dovecot] Dovecot and IPv6
by Steven King 03 Jul '10

03 Jul '10

Hello, I am trying to run Dovecot with IPv6 and IPv4. I have the following command in my conf: listen = * This makes Dovecot listen on all addresses on IPv4. I then add: listen = [::] So the conf now has both listen lines. This forces Dovecot to listen on all IPv6 addresses, but it no longer responds to requests on IPv4. Is there a way to get Dovecot to listen on both protocols? -- Steve King Senior Linux Engineer - Advance Internet, Inc.

[Dovecot] dovecot: pop3-login: Internal login failure - howto add dovecot users that are NO server users
by Hans Neukomm 02 Jul '10

02 Jul '10

Hi all my Linux system: opensuse 11.2 my mail system: postfix - dovecot my key problem since several days googling and testing is: how can I have a pop account with dovecot for a user if that user is NO linux system user it appears to me that most auth mechanisms somehow expect a mail user also to be a linux system user either to be found in the /etc/passwd or /etc/alias on my 4 servers I have NO users at all registered, NO login at all for any normal user - incl me. I strictly work as root and with serverkey auth on a tightly secured system since many years my goal is to have the most simple possible mail system - one user to send/receive (me) may be a very few friends with a pop3 account - that's that I have since many years - using cyrus. now I want to move to dovecot and I missed somehow since many days searching to find a simple howto add mail users - just for mail - pop3 and smtp, no imap, no home directory, etc I think that most of the errors I get in my mail log are about user unknown, I try different variations of postfix main.cf found in www the result always is some error like the newest dovecot: pop3-login: Internal login failures - below the last mail log - after I added a user to /etc/passwd hans:x:1000:100:xxxx yyyyyyy::/sbin/nologin ------------- dovecot: auth(default): client in: AUTH#0111#011PLAIN#011service=pop3#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011lport=110#011rport=53082#011resp=AGhhbnMASThDc2F3TzgxRHhjUmVNOHVCaDBM dovecot: auth(default): passwd-file(hans,127.0.0.1): lookup: user=hans file=/etc/dovecot/passwd dovecot: auth(default): client out: OK#0111#011user=hans dovecot: auth(default): master in: REQUEST#0112#01115510#0111 dovecot: auth(default): passwd(hans,127.0.0.1): lookup dovecot: auth(default): master out: USER#0112#011hans#011system_groups_user=hans#011uid=1000#011gid=100#011home= dovecot: dovecot: Relative home directory paths not supported (user hans): dovecot: pop3-login: Internal login failure (auth failed, 1 attempts): user=<hans>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured ------------- WITHOUT the user hans entry in /etc/passwd I get the following mail log errors ------------- Jul 1 02:43:01 kriyayoga dovecot: auth(default): new auth connection: pid=17860 Jul 1 02:43:22 kriyayoga dovecot: auth(default): client in: AUTH#0111#011PLAIN#011service=pop3#011lip=78.46.101.111#011rip=124.108.51.96#011lport=110#011rport=50152#011resp=AGhhbnMASThDc2F3TzgxRHhjUmVNOHVCaDBM Jul 1 02:43:22 kriyayoga dovecot: auth(default): passwd-file(hans,124.108.51.96): lookup: user=hans file=/etc/dovecot/passwd Jul 1 02:43:22 kriyayoga dovecot: auth(default): client out: OK#0111#011user=hans Jul 1 02:43:22 kriyayoga dovecot: auth(default): master in: REQUEST#0112#01117840#0111 Jul 1 02:43:22 kriyayoga dovecot: auth(default): passwd(hans,124.108.51.96): lookup Jul 1 02:43:22 kriyayoga dovecot: auth(default): passwd(hans,124.108.51.96): unknown user Jul 1 02:43:22 kriyayoga dovecot: auth(default): userdb(hans,124.108.51.96): user not found from userdb passwd Jul 1 02:43:22 kriyayoga dovecot: auth(default): master out: NOTFOUND#0112 Jul 1 02:43:22 kriyayoga dovecot: pop3-login: Internal login failure (auth failed, 1 attempts): user=<hans>, method=PLAIN, rip=124.108.51.96, lip=78.46.101.111 ------------- any help or pointer to a solution or howto setup dovecot pop3 accounts for non-system users would be MOST welcome greetings hans

[Dovecot] dovecot ldap search result ordering?
by chasye 02 Jul '10

02 Jul '10

I use openLDAP as dovecot pass/user db. here is main part of dovecot-ldap.conf: pass_attrs = mail=user, uid=userdb_home=/home/xadmin/%d/%$,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = SSHA user_attrs = mail=user, uid=home=/home/xadmin/%d/%$ user_filter = (&(objectClass=posixAccount)(|(mail=%u)(mailAlias=%u))) It works fine, but some account failed to get their domain in pass_attrs. I check the log. when it success, the result order is "mail, uid, userPassword" when it failed, the order is "userPassword, uid, mail" we just use a username to login. I think dovecot cant get the domain before username changed to "username@domain". So can dovecot sort the result order and How? -- 　　多情卻似總無情，　　唯覺尊前笑不成。　　蠟燭有心還惜別，　　替人垂淚到天明。

[Dovecot] dovecot 1.2.11/ thunderbird 3.1 - moving folders
by Andre Hübner 02 Jul '10

02 Jul '10

Hello List, customers telled me problem when moving folders in thunderbird which i can confirm. Following setup on my side: dovecot 1.2.11 with mbox. Thunderbird 3.1 with ready mailaccount and "Server supports folders that contain sub-folders and messages" is disabled. i create folder1 for subfolders and in folder1 a folder2 for mails. Now i create folder3 on toplevel like just like folder1 for subfolders. Now i drag/dop folder2 to folder3. Thunderbird is moving this folder successful but in folder1/.imap i can still see a folder folder2 which is containing a dovecot.index.log At this point thunderbird shows error-message when i start to delete folder1. It tells: [CANNOT] Mailbox is'nt selectable: folder1. AND [NONEXISTENT] Directory folder1 is'nt empty, can't delete it. What to do now? Is error on my or thunderbirds side? Parts of my config needed? Thanks, Andre

[Dovecot] Quota in mysql dict not properly recalculated on 1.2?
by Joan 02 Jul '10

02 Jul '10

Good morning, I am trying to add quota storage on mysql following the guide in the wiki http://wiki.dovecot.org/Quota/Dict, and I am having some problems. My setup works fine for the newly created accounts, and correctly increases/decreases quota when necessary. The wrong part seems to be the recalculation. It seems to me that the system doesn't count the real occupation when it has to recreate the quota entry for a username. This is the case: .- User test(a)testing.com has a quota 200000 bytes, I delete the entry of the database for user, and then when I do the: echo 'x GETQUOTAROOT Inbox' | USER=test(a)testing.com /usr/sbin/dovecot --exec-mail imap .- These are ALL the queries I see, I am missing the userdb queries to get the real quota. INSERT INTO quota_dovecot (bytes,username) VALUES ('0','test(a)testing.com') ON DUPLICATE KEY UPDATE bytes='0' INSERT INTO quota_dovecot (messages,username) VALUES ('0','test(a)testing.com') ON DUPLICATE KEY UPDATE messages='0' COMMIT SELECT bytes FROM quota_dovecot WHERE username = 'test(a)testing.com' SELECT messages FROM quota_dovecot WHERE username = 'test(a)testing.com' .- And the result also seems to indicate that it's not reading the quota from userdb * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS QUOTA] Logged in as test(a)testing.com * QUOTAROOT "Inbox" "user" * QUOTA "user" (STORAGE 0 1048576) x OK Getquotaroot completed. It seems to me that dovecot --exec-mail doesn't do the mysql lookups to get the usersdb. Note: attached are my dovecot -n output and the relevant .conf files

[Dovecot] address extension going into folder

02 Jul '10

Is it possible with a simple config change to make address extensions, e.g. alice+sales(a)example.com, go into a folder, e.g. .INBOX.sales, and do so ONLY if that folder already exists (and just go into INBOX if it does not exist)?
