Saw some messages before that Time wrote that the problem might be in the Dovecot.conf. What I changes was this: -- cut -- auth default { mechanisms = plain passdb passwd-file { args = /letc/deny.%Ls deny = yes } passdb pam { } userdb passwd { } user = root } -- cut -- Did I forget a '{' somewhere?

[Dovecot] POP3 protection
by Jos Chrispijn 03 Dec '06

03 Dec '06

I have some users that I will not allow to use POP3 thru my system, but force them to use webmail. Would it be possible to put an extra option in dovecot.conf to force this: # ----------------------------------------------------------------- # Logon processes # user = <username>,<password> # ----------------------------------------------------------------- user = johndoe,another_secret_password user = mike,trouble_in_paradise If unix user johndoe logs on, he cannot fetch mail thru POP3 for he has a differect password from his logon password. thanx for listening, Jos

But I still have some bad feelings about an extra sql database cause if this server is offline, my whole mailsystem is down. I fixed my problem with: http://wiki.dovecot.org/Authentication/RestrictAccess It works (thanks Jack and Timo) but now I have another little problem to solve (chaos theory lives!) > Over to you, Jos. I hope that my stupid questions still make sense after all <grin> Jos

Re: [Dovecot] Can't drop root group privileges
by Jackie Hunt 03 Dec '06

03 Dec '06

An update on my problem dropping root group privileges. I discovered this is a problem for a user if they are in the system group (gid 0). If I remove the user from the system group, and leave them in their primary group, I don't see the error. I've tried setting first_valid_gid to something like 4, hoping dovecot would filter out gid 0, but that doesn't work. Still searching for an answer... Jackie > > Hi all, > > I need your insight.

Re: [Dovecot] Marking all messages in folder as read doesn't work

Timo, On this specific point I cannot see anything wrong on my system. The maildir folders all have permissions 0700 and the messages in all folders 0600. Owner and group are the same throughout all my folders. John -- John Allen Bofferdange, Luxembourg allen(a)vo.lu http://www.homepages.lu/allen

[Dovecot] small mbox and index files problem
by Paul Shackel 03 Dec '06

03 Dec '06

Dovecot version: 1.0-0_33.rc15 built by atrpms Operating system: Redhat EL4 CPU architecture: x86 Filesystem you used: mailboxs via nfs to fileserver using xfs Just upgraded from 1.0-0_20.rc7 to 1.0-0_33.rc15 built by atrpms and we had previously set mbox_min_index_size to 1024 (1Mb) and now all mailboxes (mbox format) that are under this size are not able to be opened and throw an "Internal error occured. Refer to server log for more information." using either Thunderbird or Outlook Express, both of which are recent versions. The small mailboxes can be opened after turning mbox_min_index_size setting back to 0, at which time it creates indexes. There is nothing in the syslog file. I am looking in the right place as I can see the dovecot startup message. paul --

[Dovecot] Freebsd: fs quota / big maildir

03 Dec '06

I'm testing dovecot as courier-imap replacement. My setup: FreeBSD 6.1 nfs homedirs on FreeBSD server ~/Maildir 's LDAP auth - bind_auth=yes Seems to work well in most cases, but: - No way to read a maildir with 35000+ messages (a freebsd mailing-list for some years) => Nov 21 12:11:42 host dovecot: child 7217 (imap) killed with signal 11 - No way to have quota plugin reporting anything => quotactl(Q_GETQUOTA, /users/group) failed: Operation not supported Any idea ? What did I forget ? What could I do to debug this ?

Hi all! I need some help....changing passwords....... Dovecot server, appears to cache the old credentials. It only discovers the change upon a restart. I need to know how to configure dovecot (dovecot-1.0-0.beta2.7) as not to cache the passwords. (Using fedora core 5) Thanks Hein Celliers
