[Dovecot] Extra_fields / first check userdb?
by Leroy van Logchem 29 Nov '06

29 Nov '06

Hi, I would like to supply a few users with extra_fields. All users are found by PAM first so the userdb passwd-file doesnt seem to be used. How to alter the lookup sequence? We can't remove the accounts from the central passwd, just for Dovecot. Thanks, Leroy

[Dovecot] Authentication
by eric 29 Nov '06

29 Nov '06

Try as I may, I cannot get Dovecot to allow anything but blank passwords listed in a custom file I made for the purpose. It will not recognise anybody in passwd. Only using POP3 on an internal network so little danger of incursions. Once I created a password file with user names and no password, one user could login (from Outlook 2003) but another could not. Telnet test also fails to authenticate. I have allowed the group to write to the /var/spool/folder Syslog simply showed authentication failed. Relevant bits of my config: disable plain text = no mail extra group = users pop3 uidl format %08Xu%08Xv pasted direct from the help I have un commented auth user name characteres mechanisms = plain and I have set auth debug passwords = yes user = root System: Suse 9.3 Dovecot 1.0 rc13 Any ideas? -- John McC

Our users tend to use one of the following: Apple Mail Entourage (basically Outlook for Mac) Outlook Outlook Express Thunderbird and then there's the webmail system we provide. Apple Mail has virtually no limit on messages it will handle. I currently have over 500,000 emails in my Apple Mail. It stores email much like Dovecot; each email is in a separate file. This makes backups a breeze, which a reason to switch to a server that uses maildir. Entourage, Outlook Express and Outlook have problems if the data file exceeds 2GB. This is an ongoing problem and I'm hoping by keeping email on the server, the support headaches will be reduced. I'm not sure what limits Thunderbird has. I use Thunderbird to connect to the main directory for all email and it doesn't seem to have any trouble handling it. Currently, everyone is using POP3 but I want to move to IMAP. (Thunderbird is the only client that connects via IMAP on our systems) The motivation for moving to IMAP is primarily for spam handling. Instead of users contacting us for emails that might be caught as spam, the spam will be moved to a "junk mail" folder. Then the user can peruse the folder themselves to find any legit email improperly categorized as junk. Vacation messages is the other item that is prompting a change. Everyone is screaming for that feature.

[Dovecot] Can't drop root group privileges
by Jackie Hunt 28 Nov '06

28 Nov '06

Hi all, I need your insight. I've been testing Dovecot on an AIX 5.2 system. Compiled and running fine. We have some users on an AIX 5.1 system, so I'm working on installing it there, so we can do further testing. I'm using Dovecot 1.0 RC15 with OpenSSL 9.0.7e, configured to use port 10143 (imap) and 10993 (imaps). The error I'm seeing in the log is: dovecot: Nov 28 09:23:54 Info: imap-login: Login: user=<jackie>, method=PLAIN, r ip=xx.x.xxx.xxx, lip=xxx.xx.xxx.xx, TLS dovecot: Nov 28 09:23:54 Error: IMAP(jackie): We couldn't drop root group privil eges (wanted=200, gid=200, egid=0) dovecot: Nov 28 09:23:54 Error: child 860274 (imap) returned error 89 I've seen this error reported on the list, with the suggested resolution being to set the first_valid_gid = 0 in dovecot.conf. I've tried that, and nothing changes. Any help would be greatly appreciated!

[Dovecot] POP3 && Folders
by Timothy White 28 Nov '06

28 Nov '06

I'm sure this has come up on the list before... I have a number of accounts normally only accessed via IMAP, and for this reason, there is a global sieve script for all users (also required for the spam filtering). What this means though, is that ever users has 3-4 set folders, that are forced on. I now have a few users that want to use POP3. Is there a way to make it download all messages, in all folders, rather than just the inbox? I'm using Maildir's Thanks Tim -- Linux Counter user #273956 Don't email joeblogs(a)scouts.org.au

[Dovecot] dovecot-1.0.rc13 LDA
by Peter Bauer 26 Nov '06

26 Nov '06

Hello, I've installed dovecot-1.0.rc13 on FreeBSD-6.1 with LDA support. But I didn't found the /var/run/dovecot/auth-master file on my system. I need this file for the protocol lda { ... auth_socket_path = /var/run/dovecot-auth-master ... } settings in the /usr/local/etc/dovecot.conf. Does anyone has an idea? PS: On a older installation (dovecot-1.0.rc7) the file exists and works very well. Thanks. -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

[Dovecot] Dovecot, Postfix, Mysql and Virtual Users
by Justin Sung Kim 25 Nov '06

25 Nov '06

Hi, I am looking for a guide or manual to implement Dovecot, Postfix, Mysql and postfixadmin to manage virtual users. Can I get a help from someone? The main issue for me is the SMTP authentication with Mysql. postfixadmin stores the password in md5. How can you make that so it works on both smtp and dovecot? Please help me out. I am stuck with installing and re-installing. Thank you in advance. Justin.

[Dovecot] Thanks! Migration UWimap -> Dovecot report
by Leroy van Logchem 25 Nov '06

25 Nov '06

Best Dovecot devs, We moved from UW-imap&pop3 to Dovecot this morning (~500 accounts) and reduced our traffic from the home directory server to the imap server bigtime: | 22 Nov| 0.1 0.8| 0.0 0.0| 0.4 0.5| 1550.6 42.9| 1557.3 67.9| | 23 Nov| 0.3 1.0| 0.0 0.1| 0.4 0.6| 1331.8 37.3| 1337.2 46.3| | 24 Nov| 0.0 0.4| 0.0 0.0| 0.2 0.2| 186.8 8.8| 188.9 9.2| Yesterday and the day before we averaged 1.35 TB of NFS traffic for all the remote imap folders (mbox format) while today we only use 1/10th :) Also the lazy purge and writes are absolutly fast now, thanks! One question: Our pop3 users recieved all mail while 'leave mail on server' was enabled -it didnt delete it-. After one such run it's fine. Any idea to improve a uw/ipop3d migration for the next time? <dovecot.conf of rc15> pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh -- Leroy
