[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

[Dovecot] mailadm? authentication vs. authorization?
by David Lee 24 Nov '06

24 Nov '06

Does "dovecot" have anything similar to the UW IMAP "mailadm" group operation? From near the end of: http://www.washington.edu/imap/documentation/RELNOTES.html 'Support for SASL authentication identity vs. authorization identity in the IMAP and POP3 servers. If the user indicated by the authentication identity is in the "mailadm" group, he may specify any authorization identity and get logged in as the authorization identity user.' This allows an email administrator (member of group "mailadm") to sort out problems in a user's mailbox as that user identifier. (We try to train our users not to reveal their password to anyone, not even to our own staff. But sometimes, as staff, it is very useful to be able to do operations as a particular user to diagnose a problem.) -- : David Lee I.T.

[Dovecot] Two email accounts writing to one nfs shared home directory
by John McDonald 23 Nov '06

23 Nov '06

I use dovecot as a local imap server on my desktop machine due to the fact that my workplace only support POP3. I use fetchmail to pop, postfix to deliver, and dovecot for client access. At present I have a single email account which is the same as my system login and have postfix and dovecot setup to use ~/Maildir. The home directories on our system are served from a central file system, using nfs, which has full backup/disaster recovery policy implemented. I now need to setup a second separate email account for a specific task. Our sysadmins have setup this account for me on the POP3 server. The problem is that this account does not have a home directory on our system and therefore I can't write to ~/Maildir. What I would like to do is setup the same type of system for this second account without necessitating the creation of a home directory. That is, I would like a second Maildir folder in my own user account to which this second email account's messages are delivered. This way I will have full backup of the messages. What is the most straightforward way of achieving this? (or can it be done at all?) Thanks for the help. Regards, John McDonald.
