[Dovecot] Deliver prints passwort to the syslog
by Dominik Schulz 05 Oct '07

05 Oct '07

Hi, I've got the problem that dovecot's deliver prints the authentification information to the syslog. Like this: Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: user=user(a)domain.tld Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: password=XXXX Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: home=/home/mail/domain.tld/user Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: uid=8 Sep 18 12:11:22 mail deliver(user(a)domain.tld): auth input: gid=8 I guess that it's only a configuration option but right now I can't figure out which one I need to change to turn this off. Any help would be appreciated. Thanks in advance. Best Regards Dominik

[Dovecot] UIDL and IMAP
by Kenneth Porter 04 Oct '07

04 Oct '07

I finally got my aging FC2 box retired and moved all email to my new CentOS 5 box. My site is all-IMAP, no POP3. I have one user who downloads all email to Thunderbird on his laptop so that he can work offline while away from a network connection (eg. on an airplane). I forgot to change the pop3_uidl_format setting as described here: <http://wiki.dovecot.org/Upgrading/1.0> So he was seeing repeated downloads of all his mail (about 300 MBytes) every time he connected. (I'm not sure why it didn't happen only the first time.) I changed the setting and haven't heard back whether if fixed things for him. Does this setting in fact get used by IMAP? It's in the POP3 section, so I'm wondering if it takes effect when one is using IMAP from the client. CentOS 5 is currently shipping with: dovecot-1.0-1.2.rc15.el5 I may look for a newer release. CentOS, based on RHEL, is intended to be a conservative distro, so I'll probably need to look at RPMForge (an addon repository of more exotic and bleeding edge software) to see if it offers a newer release.

[Dovecot] Dovceot user pop3 last connect info?
by Tim Tyler 04 Oct '07

04 Oct '07

Dovecot experts, I am a newbie to Dovecot. I am in the process of replacing qpopper with dovecot to support pop 3 clients. I have installed the latest version of Dovecot on Fedora Core 6. Everything seems to be working fine using ldap, etc. However, with qpopper, I used to have .pop.username files which would give me a time stamp of the last time a user established a pop3 connection. I know that Dovecot has logs of connection in the /var/log/maillog files, but these files rotate out over a relatively short period of time. Is there a method by which one can keep track of the last time a pop3 connection was established for each user when using Dovecot? Tim Tyler Network Engineer - Beloit College tyler(a)beloit.edu

[Dovecot] Namespace "hidden" option not working?
by Ed W 04 Oct '07

04 Oct '07

I either misunderstand the namespace hidden option, or else perhaps it's not working correctly in 1.0.5? dovecot.conf # default namespace namespace private { separator = / prefix = inbox = yes hidden = yes } # for backwards compatibility: namespace private { separator = . prefix = INBOX. inbox = yes } Then login and test s6jh LIST "" "*" SND: <<< len(939) Comp_len(118) Time:0.137985 * LIST (\HasNoChildren) "/" "Diary" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Archive" * LIST (\HasNoChildren) "/" "Sent Items" * LIST (\HasNoChildren) "/" "Subdir" * LIST (\HasNoChildren) "/" "Junk E-mail" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Deleted Items" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "."

"INBOX" The idea was to support an old client using Courier like access whilst still letting new clients access using the normal process Ed W

by Dominique Feyer 04 Oct '07

04 Oct '07

I work on a dovecot cluster (15 servers) we need to add a new storage array and move the data for a list of user from the old storage to the new one. We use dovecot proxy to redirect imap and pop3 to the same server everytime. How to disable pop3 and imap access during the data migration process (duration 5 minutes to 10 minutes). Can i send a custom error message to our users ? Thanks for your help Dominique Feyer

[Dovecot] In-site migration from /etc/passwd to LDAP
by Maykel Moya 04 Oct '07

04 Oct '07

I'm doing in-site migration of accounts from /etc/passwd to an LDAP directory. The migration should be progressive (not all users at the same time). I'm already able to check mail for accounts in /etc/passwd and accounts in LDAP. The problem is with mail delivery. I'm using Postfix + Dovecot-LDA. This is the error I get with every delivery -- dovecot: Oct 03 00:16:09 Info: auth(default): master in: USER 1 moya service=deliver dovecot: Oct 03 00:16:09 Info: auth(default): ldap(moya): user search: base=ou=users,dc=sld,dc=cu scope=subtree filter=(&(objectClass=posixAccount)(uid=moya)) fields=sldMailbox,uidNumber dovecot: Oct 03 00:16:09 Info: auth(default): master out: USER 1 moya home=/srv/vmail/m/moya/ uid=29174 gid=101 deliver(moya): Oct 03 00:16:09 Fatal: setuid(29174) failed: Operation not permitted -- 29174 is the uid for moya, is the same in /etc/passwd or in LDAP via posixAccount class. Any advise please? Regards, maykel

[Dovecot] new antispam plugin
by Johannes Berg 03 Oct '07

03 Oct '07

Sparked from the discussion on the list, I've put my antispam plugin into git and split up the code into a frontend and possibly multiple backends. See http://git.sipsolutions.net/dovecot-antispam.git/ (URL functions as both gitweb and git URL) Andreas, I took your README file and adjusted it, I hope you don't mind. I didn't fork from your git tree because you'd already implemented the libdspam backend there. Maybe you could take a look at the new backend/frontend separation and implement a libdspam backend. Aria, it should be possible to write a spamassassin plugin, quite easily if spamassassin supports training based on signatures, not quite so easily otherwise though I intend to plan this. Timothy, you could write the mysql logger as a backend too. I take patches :) Oh and as always thanks to Timo for implementing such a nice server and string, memory and mail handling API. johannes
