[Dovecot] disable_plaintext_auth = no ignored by dovecot in Ubuntu 10.04
by David Mattox 31 Jan '11

31 Jan '11

Help!! I have been trying to get Dovecot configured to allow plaintext auth with no success. After some testing with the mail system I discovered the >dovecot -a commant to dump the config file values from the program. Gee, changing the value of disable_plaintext_auth had no effect on what the program reported this value to be! To eliminate possible errors caused by other config file entries I finally restored the /etc/dovecot/dovecot.conf file that was created by installing the package. I then changed the one line to uncomment disable_plaintext_auth and set it equal to no. restart the box and execute dovecot -a The value is still set to the default value of yes... Help! What is happening and how to I get this system to allow plain text auth without TLS? I did also try setting different ports for imap, imaps, pop3, pop3s inside the seperate protocol blocks with no effect. Below you will find a partial of the config file. Below that you will find the output of >dovecot -a and >dovecot -n Thank you in advance for any help with this problem.

[Dovecot] Particular user post-login hang
by Henry C. 31 Jan '11

31 Jan '11

Greets, I'm using dovecot 2.0.9 (also tried rolling back to 2.0.8 which does the same - the output below is from 2.0.8), and this problem is imap specific. The following is a recurring problem with a specific user - as far as we can tell, other users are working just fine (there are thousands); but I bet there are others. In a nutshell: User authenticates OK, then the imap process hangs. It's almost as if something in the user's inbox is causing the problem, since if I clear all emails (and cache), then things work fine. The user will then receive emails OK for some random period (maybe a few days) and be able to read/write OK via imap, and the problem will re-occur. The debug output shows nothing untoward: auth: Debug: auth client connected (pid=20774) auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=144 rport=41641 resp=<hidden> auth: Debug: shadow(username,127.0.0.1): lookup auth: Debug: client out: OK 1 user=username auth: Debug: master in: REQUEST 1938161665 20774 1 238230058d076a9af1cd4405244d33ba auth: Debug: passwd(username,127.0.0.1): lookup auth: Debug: master out: USER 1938161665 username system_groups_user=username uid=17286 gid=300 home=/home/mailusers/username imap-login: Info: Login: user=<username>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=20775, secured imap(username): Debug: Effective uid=17286, gid=300, home=/home/mailusers/username imap(username): Debug: fs: root=/home/mailusers/username/., index=, control=, inbox=/var/mail/username Rawlog looks good: IN: A002 CAPABILITY A003 NAMESPACE C64 EXAMINE "" A002 STATUS "INBOX" (MESSAGES UNSEEN RECENT) A003 SELECT "INBOX" A004 EXPUNGE A005 SELECT "INBOX" A006 EXPUNGE A007 UID SEARCH UNSEEN A008 UID FETCH 2533:2588 (FLAGS BODY.PEEK[HEADER.FIELDS (RECEIVED)]) OUT: ... * 15 FETCH (UID 2536 FLAGS () BODY[HEADER.FIELDS (RECEIVED)] {944} ... * 67 FETCH (UID 2588 FLAGS () BODY[HEADER.FIELDS (RECEIVED)] {945} ...

[Dovecot] dovecot can't see mail that is there

Hi list, I've yet to figure out what's the issue with my installation, why I can't see the mails that are definitely there. I've updated with last package: dovecot-2.0.9-1.fc14.x86_64.rpm and performed the following test: 1) send a simple 2 lines test mail from "root" to user "testdvct" with alpine 2) login under "testdvct" + run alpine + list (only list, not read) the mail: +------------------------------ Alpine Output --------------------------------------+ | ALPINE 2.02(1266) MESSAGE INDEX Folder: INBOX Message 1 of 1 NEW | | | | + N 1 17:43 root (881) | +--------------------------------------------------------------------------- --------+ so it tells me I've got one mail from root 3) I issue the command: "strace -o strace-dovecot.txt -p 2218" where 2218 is the /usr/sbin/dovecot PID 4) telnet into pop3: # telnet localhost pop3 Trying 127.0.0.1...

[Dovecot] Duplicate messages when moving message to inbox
by Ron Garret 31 Jan '11

31 Jan '11

Hello, I am encountering a strange problem but I'm not sure if it's a dovecot problem or a Mac Mail problem. The symptom is that if I move a message from a folder into my inbox the message ends up showing up as a duplicate in Mac Mail. On the server it's still just one message. This ONLY happens when I move a message IN to the inbox. It does not happen when I move a message out of my inbox into a folder, or when I move a message between folders. I can force a sync on Mac Mail and the duplicate is still there. If however I quit Mac Mail and start it up again, the duplicate disappears. I can move one of the duplicated messages out of my inbox into a folder and then back into my inbox repeatedly and end up with (apparently) an arbitrary number of copies of the same message. On the server, though, there is still only one file. Surely I'm not the first person to have encountered this behavior? Does anyone happen to know if this is a dovecot bug or a Mac Mail bug (or, hopefully, a configuration problem)? Thanks, rg

It's a theoretical problem mostly, especially in your case. It's mainly visible when doing stress testing with large maildirs. I doubt in regular use it matters.

First, my problem. Settings are below that... Everything works fine - I can login to webmail (users are tied to LDAP). I can send and receive email via my Thunderbird Client. However in my mail.err log I see lots of messages that say: dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN 1.) What does that mean, and how can I solve it? 2.) With regards to pop3s I am not altogether sure that I am using the right config in my dovecot.conf file (also below). Can someone let me know?

[Dovecot] inform users's about new spam
by ckubu 30 Jan '11

30 Jan '11

Hallo evryone! Mailsetup: postfix+dovecot2 with postgres database backend - about 2,000 virtual mailboxes, growing.. New possible spam will be sorted into a users directory named "spam", emails older than 30 day's in that folder will be deleted by using expunge. I would like to inform my users evry two day's (or something like that) about new emails in the spam folder. Can you give me a hint how to handle that ? Are there helpful tools , or have i to wrote my own script, walking through the folders, checking for new emails since last check and finally inform the user if needed. Best wishes Christoph

[Dovecot] Copying sieve scripts
by Christoph Pleger 30 Jan '11

30 Jan '11

Hello, I am using squirrelmail with avelsieve to edit my filter rules. The filter rules are like this: 1. If the message contains a virus, delete the mail and notify me by email. 2. If the message is spam, deliver it to my spam folder. 3. If the message is from the dovecot mailing list, deliver it to my dovecot folder Yesterday, I created a new user and wanted to let him have rules 1 and 2 like above, only with another destination for email notification. So, I copied my sieve script into the sieve directory of the new user, deleted rule 3, changed the destination for email notification and then called sievec to compile the rule set. But this did not work like expected: Using squirrelmail, I saw that the new user had only rules 1 and 2, but the destination in rule 1 still contains my email address. My own account still has three rules. So, this simple way of copying sieve scripts does not work. Is there another way to copy sieve rules from one user to another? Regards Christoph

[Dovecot] sql : uid, gid, home ignored ?
by Eric Diaz Fernandez 30 Jan '11

30 Jan '11

Hello, I'm trying to setup a dovecot imap server. version is 2.0.9 I've setup a mysql database using: user_query = \ SELECT home, uid, gid, home as userdb_home, uid as userdb_uid, gid as userdb_gid, \ FROM user WHERE username = '%n' AND domain = '%d' AND active = 'Y' password_query = \ SELECT username AS user, password, home as userdb_home, uid as userdb_uid, gid as userdb_gid, home, uid, gid \ FROM user WHERE username = '%n' AND domain = '%d' AND active ='Y' (I get the information with and without the userdb_ prefix since I was not sure what was needed) When I login, I see the password_query in the debug log and it says: client out: OK 1 user=theuser home=/home/theuser uid=1000 gid=1000 master in: REQUEST 547880961 10068 1 e6...(hexadecimal stuff) master out: USER 547880961 theuser But in the mail.err log i see: dovecot: imap(theuser): Error: user theuser: Couldn't drop privileges: User is missing UID (see mail_uid setting) dovecot: imap(theuser): Error: Internal error occurred. Refer to server log for more information. The same two lines are also displayed in mail.info and mail.log Further testing (setting mail_uid & mail_gid to a nobody) shown that the home setting was ignored too. The sql example says that uid and gid are supposed to be an override of the mail_uid and mail_gid settings. Any idea of why the columns are ignored ? Thanks in advance, Eric

[Dovecot] Cooperating with dovecot in its Maildir
by Rob Browning 29 Jan '11

29 Jan '11

Is it possible to cooperate with dovecot within its Maildir, and if so, what's required? In this particular case, we're thinking of trying to allow notmuch to operate directly on the dovecot Maildir, and at the moment, the only modifications notmuch makes are to change maildir flags. Would locking dovecot-uidlist.lock be sufficient, perhaps via liblockfile? Also, is there some reliable way to detect a dovecot Maildir? For example, are any of the dovecot-* files guaranteed to exist all the time? Thanks -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4

[Dovecot] How do I do this with mdbox?
by Odhiambo Washington 29 Jan '11

29 Jan '11

In my life with Maildir, mails were stored as single files, each mail per file. It was pretty easy to resend an e-mail from a Maildir folder to another address, by causing the mail to be re-injected into my MTA (Exim) queue for processing: I'd use a very simple shell script to achieve the above: #!/bin/sh email=$(find $*) { for x in ${email}; do sendmail president(a)egypt.gov < ${x}; done } Now, with mdbox container/storage, it beats me how to achieve the same. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] Sharing user folders doesn't work when users have periods in names.
by ian+dovecot＠comtek.co.uk 28 Jan '11

28 Jan '11

I am using period as an IMAP separator with Maildir directories and I cannot share folders where the user has a period in their name. Suppose I log in as 'some.user' and do: SETACL INBOX mailtest(a)example.co.uk +lrwstipekxacd /var/mail/virtual/users/some.user/Maildir/dovecot-acl is created, with appropriate contents and shared-mailboxes.db gains an entry for 'shared/shared-boxes/user/mailtest@example.co.uk/some.user@example.co.uk'. mailtest is simply unable to see a new folder. As mailtest 'a LIST "" "Users.*" ' is empty. If I do ' a MYRIGHTS Users.some.user.INBOX ' I get 'NO [NONEXISTENT] Mailbox doesn't exist: Users.some.user.INBOX' and, oddly, a new maildir appears: '* LIST (\Noselect \HasChildren) "." "Users.some" ' -- it also creates an empty folder structure with a single file /var/mail/virtual/users/some/Maildir/dovecot-acl-list too! Is there a workaround that does not involve rebuilding every user's Maildir with backslash as a separator? Thanks, Ian

Hi, i'm new on sieve, but want to use ist with sogo. The Problem is, that when i set a redirect or vacation rule like: redirect "email(a)example.com"; (real Adress is different) the sieve says the mail would be forwarded, but no mail is sent. (No Action in /var/log/maillog) And because there is no Error-Message it's difficult to search for...

[Dovecot] Telnet access creates new maildir folders
by Seasoul 28 Jan '11

28 Jan '11

Hi, I am running Dovecot Version 1.0.15on a Debian server, with postfix and postfixadmin. My mailbox base is /var/mail/vmail When I send an email to a user1(a)domain.com for the first time, the user "mail" creates a set of dovecot folders under /var/mail/vmail/ user1(a)domain.com/ and my new emails are found in /var/mail/vmail/ user1(a)domain.com/new When I test my server using telnet (telnet domain.com 110), I can log in fine as a user1, but when I type "LIST", it tells me there are no emails. And I realize a new set of dovecot folders were created under /var/mail/vmail/user1/ ! The folders are created by the user "user1". Obviously the folder "new" under that is empty, since my emails received are in /var/mail/vmail/user1(a)domain.com/new and not /var/mail/vmail/user1/new . Therefore, connecting with an email client via POP also shows an empty inbox. I am lost as to what to do to fix this, and how to let the server know that pop access should be looking into /var/mail/vmail/user1(a)domain.com/ instead of /var/mail/vmail/user1/ . Hopefully someone on this list will be able to save me from my misery :) Cheers Sea

[Dovecot] Best way to calculate concurrent users?
by Henrique Fernandes 28 Jan '11

28 Jan '11

Well, i am having some problens to figure out how many concurrent users into the server! In my envoriment now, most people are using the webmail interface, and it just conect and disconct pretty quickly so i can not get it with "doveadm who" doveadm who only gets the ones that are connect with clients. O use ipvs to balance betwaeen 2 servers does anyone have an ideia ? With ipvs i get this results: IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP XXX.XX.X.XX:143 lblcr -> 10.0.2.10:143 Masq 1 16 228 -> 10.0.2.11:143 Masq 1 16 184 There is others ports and stuff. Does any one have an ideia how to get this number ? []'sf.rique

[Dovecot] Storing Dovecot index files on sql
by list＠airstreamcomm.net 28 Jan '11

28 Jan '11

We have been communicating with the mailling list on another thread regarding dotlocking on the dovcot-uidlist over an NFS share, and I was hoping to get some ideas on whether or not a sql database would be a suitable location for storing the dovecot index files. Our though process so far has been that storing the index files on NFS with the maildir has not worked very effectively when we are using multiple Dovecot servers (even using sticky IPs in our load balancer), and using local storage is not possible with a cluster of machines, so we got to thinking about what type of storage platform would be suitable for these index files that would provide native locking of the data while multiple servers accessed and wrote to it. Our question to the community is whether sql storage for index files has ever been considered, what issues would this introduce, and if it's even feasible? Thanks everyone! Michael

[Dovecot] Differenft INBOX for IMAP/POP with checkpassword passdb
by Peter Mogensen 27 Jan '11

27 Jan '11

Hi, I'm trying to do a setup where IMAP and POP users see different INBOX' Like described on the virtual folder wiki page: http://wiki.dovecot.org/Plugins/Virtual However, for now, I'm stuck with the checkpassword passdb and prefetch userdb So I can't parameterize the result on %s like the example with MySQL does. So I thought of having to different checkpassword scripts: passdb checkpassword { args = /usr/bin/checkpassword-%s } However, Dovecot (1.2.15) doesn't seem to expand %s even though the Wiki says it should be available everywhere: http://wiki.dovecot.org/Variables Is this a bug, or am I missing something. /Peter

[Dovecot] Best Cluster Storage
by Jonathan Tripathy 27 Jan '11

27 Jan '11

Hi Everyone, I wish to create a Postfix/Dovecot active-active cluster (each node will run Postfix *and* Dovecot), which will obviously have to use central storage. I'm looking for ideas to see what's the best out there. All of this will be running on multiple Xen hosts, however I don't think that matters as long as I make sure that the cluster nodes are on different physical boxes. Here are my ideas so far for the central storage: 1) NFS Server using DRBD+LinuxHA. Export the same NFS share to each mail server. Which this seems easy, how well does Dovecot work with NFS? I've read the wiki page, and it doesn't sound promising. But it may be outdated.. 2) Export block storage using iSCSI from targets which have GFS2 on DRBD+LinuxHA. This is tricky to get working well, and it's only a theory. 3) GlusterFS. Easy to set up, but apparently very slow to run. So what's everybody using? I know that Postfix runs well on NFS (according to their docs). I intend to use Maildir Thanks
