[Dovecot] auth timeout state=2, bad?
by Bernhard Schmidt 22 Oct '12

22 Oct '12

Hello, we run Dovecot 2.1.7 as SASL backend for our Postfix SMTP-AUTH farm and see this error message occasionally Oct 22 16:15:32 lxmhs52 dovecot: auth: PLAIN(?,xx.xx.xx.xx): Request 0.21 timeouted after 150 secs, state=2 Since it is mostly the same IP repeating I'm assuming it's a client issue. Is that correct? What could cause this? Can we safely ignore it? Thanks, Bernhard

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from. Use *different* column or table name in your dict file where dovecot may write the current storage/message count. > dovecot-dict-sql.conf.ext > > map { > pattern = priv/quota/storage > table = virtual_users > username_field = user > value_field = quota value_field should be current_quota_storage (writable column) > } > map { > pattern = priv/quota/messages > table = virtual_users > username_field = user > value_field = quota_messages value_field should be current_quota_messages (writable column) > I'd like to know why these columns are updating. Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.
