[Dovecot] dovecot: pop3-login: Disconnected (tried to use disabled plaintext auth): method=PLAIN
by John Espiro 30 Jan '11

30 Jan '11

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
