[Dovecot] major pop3+ldap problem with alpha3 and alpha4
by Udo Rader 07 Nov '05

07 Nov '05

hi, For some of our customers we provide a pop3 access, and after an upgrade to alpha3, it is not working anymore. All of our data is ldap based and everything is working as before for our IMAP customers, but our POP3 users fail. Obviously the pop3 login process does not read the data correctly that comes from ldap. after enabling mail_debug, I saw the following error in our log: --------CUT-------- dovecot: Nov 02 18:01:32 Info: pop3(some.one.at.work): mbox: data=/virtual/at.work/home/some.one/mail/:INBOX=/var/mail/some.one.at.work --------CUT-------- The INBOX should be /virtual/at.work/var/mail/some.one.at.work, yet the POP3 process obviously uses the default_mail_env settings. the relevant line in our dovecot-ldap configuration looks like this: -------CUT-------- user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber -------CUT-------- As I said, the IMAP process uses the ldap data correctly. any ideas?

[Dovecot] deleteing e-Mail, quota and dovecot
by Götz Reinicke 07 Nov '05

07 Nov '05

Hi, we run a RHEL4 E-Mail-Server with dovecot-0.99.11-2.EL4.1. we use mbox and most users use imap. So I have set quota for the devices where the user mailfiles are saved. No I'm getting the situation, that users exide there quota but yet not the grace limit and the user isn't able to delete messages. e.g. the the soft limit is 100 MB, the hard limit is 110 MB. So there should be some space to delete unneeded emails. Am i thinking the wrong way? Or how should the quota-system work in this situation? Thanks for any ideas!

[Dovecot] Setup help
by Patrick Ernst 06 Nov '05

06 Nov '05

I'd previously had dovecot running on a Debian server but recently migrated to Suse. The nice, simple setup for dovecot on debian is not as easy using the dovecot sources. My lack of experience I'm afraid! I'd like to continue to use dovecot, especially as my current maildir directories are all set up ready to be use again. On suse (sles9) I have users authenticating by LDAP. In /var/log/dovecot I am getting errors like dovecot: Oct 27 22:17:41 Warning: Killed with signal 2 dovecot: Oct 27 22:28:03 Error: auth(default): LDAP: ldap_simple_bind_s() failed (dn uid=dovecot,ou=people,dc=aro,dc=home): Protocol error The errors also include the same LDAP error but with signal 11 or 15 I cannot get dovecot working. I've tried the 1.0 alpah and also found an earlier version on the suse 10 DVD. Basically I'm looking to use the IMAP server to centrally store emails on our home/business server. Previously we've been downloading mails (POP) from various mail accounts and moving them to dovecot (debian). In the future, I'd like to use fetchmail to do this part and locally deliver mail. My LDAP domain base is dc=aro,dc=home. I generally use this as the local mail/DNS domain as well. I have edited both /usr/local/etc/dovecot.conf and dovecot-ldap.conf. When I run dovecot it fails to start. I wonder if someone, in fairly broad ters could give me the steps for getting dovecot running with LDAP authenticated users? Regards Patrick

[Dovecot] cache
by Lucas 05 Nov '05

05 Nov '05

Hi, I just update from 0.99 to 1.alpha4. I combined with squirrel since several years ago and all was like a charm. Now dovecot is like catching mails. I explain: - I sent an email to my account. I login to webmail and I could see the mail. - Then, I check my mail with an email client through pop3 (vpopmail). - After that the mail isnŽt in the server, but in the webmail appears one msg in Inbox folder and the header. When click to see the msg an error ocurred: Query: FETCH 1 (FLAGS BODYSTRUCTURE) I try this in my config file: mail_never_cache_fields = flags date.sent date.received size.virtual size.physical mime.parts imap.body imap.bodystructure But no success :( Thank you in advance, Lucas

[Dovecot] forcing a default namespace
by Glenn Leavell 04 Nov '05

04 Nov '05

According to the Dovecot documentation, a "default namespace" is defined by simply configuring the namespace with an empty prefix, as in: namespace private { separator = / prefix = inbox = yes hidden = no } But my experience has been that this doesn't provide a true default, and that this namespace will only be selected when the client actually provides an empty ("") prefix. Is there a way to configure a default namespace that will always be chosen no matter what prefix the client provides, as long as there isn't an explicit match? I'd like to be able to have clients find mailboxes in a particular location no matter what they provide as their folder prefix.

[Dovecot] Dovecot 1.0a4 + pam + winbind ?
by Stephen Lee 04 Nov '05

04 Nov '05

Hi, I would like dovecot/pop3 to authenticate against a Windows ADS server. I've got authentication working for Samba and ssh using pam_winbind.so. Here's what my /etc/pam.d/dovecot file looks like: #%PAM-1.0 auth sufficient pam_winbind.so #auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth account sufficient pam_winbind.so session required pam_stack.so service=system-auth session sufficient pam_winbind.so and this is what a portion of the dovecot.conf file looks like: auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous mechanisms = plain passdb pam { args = dovecot } userdb passwd { } user = root } To get SSH to authenticate against ADS, the user name has to be prefaced with the domain name like "domain\user1". This is what I get when I attempt to login to Dovecot via Outlook/pop3 with the same naming scheme: Nov 3 20:09:45 server2 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.3 rip=192.168.0.227 resp=AHZjXGpvYW5uZQBqb2FubmU= Nov 3 20:09:45 server2 dovecot: auth(default): plain(domain\user1,192.168.0.227): Username contains disallowed characters Nov 3 20:09:46 server2 dovecot: auth(default): client out: FAIL 1 user=domain\user1 Nov 3 20:09:46 server2 dovecot: pop3-login: Disconnected: user=<domain\user1>, method=PLAIN, rip=192.168.0.227, lip=192.168.0.3 Dovecot does not like the "\" character and I'm note sure authentication gets past that step to get to the pam phase. Any experiences and suggestions with Dovecot authentication against Windows Active Directory? Thanks, Stephen

[Dovecot] courier2dovecot migration script
by Arto Bendiken 03 Nov '05

03 Nov '05

Howdy, I've just migrated a couple of servers to Dovecot, and am loving it so far. I thought I'd share the courier2dovecot shell script I whipped together (based on the instructions I found in the wiki.dovecot.org migration how-to), for converting Courier-IMAP maildirs to Dovecot format. It can be downloaded from my home page: http://bendiken.net/scripts/ While the script is rather simple, it can save a fair bit of typing when migrating some hundreds of mail accounts... especially since Courier stores some of its own state files recursively in each folder of the maildir hierarchy, making it a real pain to otherwise manually rename or remove all of them. Here's a plain-English summary of what the script currently does, when given a Courier maildir path as an argument: - check that the given path is indeed a valid Courier maildir, and exit if not - rename the file 'courierimapsubscribed' to 'subscriptions', and strip the 'INBOX.' prefix from its contents - recursively rename all of files of the name 'courierimapuiddb' to 'dovecot-uidlist' - recursively delete all of files of the name 'courierimaphieracl', 'courierimapacl' and 'courierimapkeywords' The script will also verbosely print out each action it does, handy for redirecting the output to a log file for a large migration. I hope people about to jump ship from Courier to Dovecot find this useful. If anyone comes up with improvements to the script, please send them my way :-) Arto

[Dovecot] Ambiguous ..... problem using Dovecot v1.0.alpha4 on OpenBSD 3.8
by snoop＠email.it 03 Nov '05

03 Nov '05

I verified that "default_mail_env" on my dovecot configuration file are "maildir:" correctly prefixed and ... permissions of /var/mail/mydomain and /var/mail/mydomain/myuser are 2755 and owner is root:mail. Dovecot user is member of mail group. I'm sure that isn't an authentication problem. I've tried some days to understand and to find over internet but I've not find a solution and now ... doesn't want to work. Someone can help me? _________________________________ Log output: dovecot: Nov 03 20:20:39 Error: imap(myuser(a)mydomain.com): Ambiguous mail location setting, don't know what to do with it: /var/mail/mydomain.com/myuser (try prefixing it with mbox: or maildir:) dovecot: Nov 03 20:20:39 Error: imap(myuser(a)mydomain.com): Failed to create storage with data: /var/mail/mydomain.com/myuser -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Registrazione dominio, 500 MB per la posta elettronica, spazio web a partire da 2,92 Euro al mese e in pi� assistenza gratis! clicca qui Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=4079&d=3-11

[Dovecot] assertion problems w/ 1.0alpha4
by Jeremy Brown 03 Nov '05

03 Nov '05

Hey list, I have been using 0.99.14 for a while now but recently decided to try to upgrade to 1.0alpha4 to get the latest and greatest. I'm building from source myself on a Slackware 10.0 machine. Slackware ships with UW-IMAP configured to keep your inbox in /var/spool/mail and your other folders in ~/. I've been using the same setup for dovecot so that the migration is smooth...so my default_mail_env is set to: default_mail_env = mbox:~/:INBOX=/var/mail/%u I'm able to connect to both pop and imap servers and authenticate myself, but as soon as I attempt to get a listing of my emails my dovecot setting crashes with the following in the mail logs: Nov 3 10:52:40 shallowhal dovecot: imap(jeremy): file mail-index-sync-ext.c: line 155 (get_ext_header): assertion failed: (memcmp((char *)(ext_hdr + 1), ext->name, strlen(ext->name)) == 0) I can trigger this over POP3 just by logging in, then issuing "USER username", "PASS password", and then "LIST". Anyone experienced anything like this before? Any ideas on what might be going on? I can include more debug information (like my dovecot.conf file) if it would help. Jeremy

FW: [Dovecot] How to log POP3 events
by Cliff Hayes 03 Nov '05

Ok, I think I have that figured out. I made the following mods: disable_plaintext_auth = no pop3_uidl_format = %08Xu%08Xv and it seems to work. Now...about those enhanced logging capabilities.
