[Dovecot] Dovecot 2.1 Panic
by Alexandr Sabitov 27 Nov '13

27 Nov '13

Hi, Dovecot 2.1.12 sends panic message when it tries to authenticate some users. Apparently because they use different authentication mechanisms on different email clients at the same time. For example, in debug logs this user uses CRAM-MD5, NTLM and PLAIN in account settings of his email clients. All passwords are stored in plain text (base64) in LDAP. Please advise me what I can tweak to fix this issue ?

[Dovecot] Dovecot software testing and release practice
by Andreas Kasenides 26 Nov '13

26 Nov '13

Since this, it seems, was lost in, the now infamous, 2.2.9 thread I would like to resubmit the following proposal for Timo's consideration. Thanks Timo for doing an excellent job. I believe that the following will add further value to Dovecot in the long run. Thankx Andreas ============================ > On 23-11-2013 3:47, Noel Butler wrote: > > On Fri, 2013-11-22 at 10:14 +0100, Ralf Hildebrandt wrote: > * Thomas Leuxner <tlx(a)leuxner.net>: > * Ralf Hildebrandt <Ralf.Hildebrandt(a)charite.de> 2013.11.22 > 09:44: > > Which patch? > > > http://www.dovecot.org/list/dovecot/2013-November/093654.html > Pigeonhole related patches. > Damn.

I also propose that upon employing above strategy that Timo should come up with a release cycles (long term, short term) with announced targets. Patches should be released as patches strictly as needed, not releases, and should be announced on a low traffic list like he is already doing with releases. OR something along these lines. I know these are growing pains but essential. Email systems are CRITICAL for most of us. Andreas

[Dovecot] Problem with Thunderbird and mailbox with SPECIAL-USE flag
by Sylvain 26 Nov '13

26 Nov '13

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with the great Dovecot. SOGo webmail is connected to the proxy and works great (very very more fast) but I have a problem with Thunderbird : mailbox with « SPECIAL USE » aren't automatically detected. To make that works, I must : - in Dovecot : define the namespace inbox : « prefix = » and « separator = . » - in Thunderbird : force in the account, the personal namespace to "INBOX." and untick « Allow server to exceed namespace » (sorry : personal translation :D). If I define in the namespace inbox as the dovecot wiki said : « prefix = INBOX. » and « separator = . », TB see a sub-folder INBOX and mailbox with special use aren't automatically detected. :-( I must have forgotten a parameter in my Dovecot configuration but I don't see it.. Can you have a look please ? Here my configuration : # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 auth_debug_passwords = yes auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 100 imapc_host = xxxxxx mail_gid = imapproxy mail_home = /var/local/cache/dovecot/%1Mu/%1.1Mu/%u mail_location = imapc:~/imapc mail_uid = imapproxy namespace inbox { inbox = yes list = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = . type = private } passdb { args = host=xxxxxx port=143 default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = imap } protocols = imap ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = prefetch } Sylvain

[Dovecot] 2.2.9
by Nick Edwards 26 Nov '13

26 Nov '13

Timo (since he is the only one that maters here), In past couple of days I have seen 4 people on IRC bitten by 2.2.8 and pigeonhole bug, none of them are on this list, so like all others who want to download and build them, are unaware of the patch, so, given how wide the userbase is with pigeonhole sieve and dovecot, this would or should be considered a serious bug, so my question is Timo, is it not best to immediately push 2.2.9, or should even more server administrators become frustrated and curse waiting two more months until you have a list you think is best putting out a new release, many of them dont like the constant new releases all the time with only minor things, but with a build failure, thats a serious issue.

Noel, I include you in the gang of three, and I only read half the posts on this list. I have no specific reason to, but it isn't a good association. A decade ago I was active on the Pegasus mail and Mercury lists, and names stood out after a while. Unfortunately on this list, the names stand out for a completely different reason - and its not positive. Just chill, everyone. You never know who's going to interview you in a year. Rick

[Dovecot] postfix and dovecot - no emails in new folder
by Don Hill 26 Nov '13

26 Nov '13

Hi. I am working on setting up Dovecot v2.0.9 and postfix 2.6.6 on centos 6.4. I have postfix configured with dovecot using virtual users. Everything seems to be working with the exception of no emails being delivered to the Maildir/new folder. If I touch a file into that folder then the file gets delivered to the email client using imap. I can also send email from the client with no problems. In fact if I look at the logs postfix says the email was delivered to the mailbox. postfix/virtual[27270]: 8652F35C38A8: to=<user(a)domain.tld>, relay=virtual, delay=0.11, delays=0.1/0.01/0/0, dsn=2.0.0, status=sent (delivered to mailbox)$ Here is my dovecot -n output *doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf** **doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:85: protocol { ssl_listen } has been replaced by service { inet_listener { address } }** **# OS: Linux 2.6.32-042stab079.6 x86_64 CentOS release 6.4 (Final) reiserfs** **auth_mechanisms = plain login** **default_login_user = vmail** **first_valid_gid = 5000** **first_valid_uid = 5000** **listen = *** **mail_access_groups = vmail** **mail_location = maildir:/var/vmail/%d/%u/Maildir** **mbox_write_locks = fcntl** **passdb {** ** args = scheme=SHA1 /etc/dovecot/passwd** ** driver = passwd-file** **}** **protocols = imap pop3** **service auth {** ** unix_listener auth-client {** ** group = postfix** ** mode = 0660** ** user = postfix** ** }** ** user = root** **}** **service imap-login {** ** inet_listener imaps {** ** address = *** ** }** ** process_min_avail = 1** ** user = vmail** **}** **service pop3-login {** ** inet_listener pop3s {** ** address = *** ** }** **}** **ssl_cert = </etc/pki/dovecot/certs/dovecot.pem** **ssl_key = </etc/pki/dovecot/private/dovecot.pem** **userdb {** ** args = uid=5000 gid=5000 home=/var/vmail/%d/%u allow_all_users=yes** ** driver = static** **}* Any thoughts?

[Dovecot] Zlib plugin - when does it make sense?
by Frerich Raabe 25 Nov '13

25 Nov '13

Hi, I run a small IMAP server for a dozen guys in the office, serving about 55GB of Maildir. I recently became aware of the Zlib plugin ( http://wiki2.dovecot.org/Plugins/Zlib ) and wondered 1. given that there is about zero CPU load on my IMAP server, is enabling the plugin a no-brainer or are there other things (except CPU load) to consider? 2. For enabling the plugin, I suppose you compress all the existing mail just once and then add 'zlib' to mail_plugins in order to have all future incoming mail saved? Any insight by people familiar with the plugin would be much appreciated - thanks! -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing
