[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

Hello again, I'm running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam : dovecot 2.2.8 (it was working fine with 2.2.6 after doing a chmod 4511 on dspam binary), dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429 (recompiled after each dovecot upgrade). I've set dspam to debug, and mail_debug to yes. uid 1001 is user vmail (dovecot is running under vmail) gid 12 is group mail (vmail is a member, with mail,postfix,dspam,dovecot,apache) All the necessary users are trusted in dspam configuration.

[Dovecot] Checkpassword interface for custom password check and home mounting
by Jouko Nikula 25 Nov '13

25 Nov '13

Hi, I'm trying to use the checkpassword interface to do a password check and if the check succeeds I mount the user home directory (including mail) using the users login password and uid. My password check seems to work, but when I add the home directory mounting things seem to stop. Dovecot never logs the result of the password check and nothing happens until the client gets bored and tries again. I added trace to the dovecot's checkpassword-reply and I see that it's really executed, it writes the reply and returns 0 for successful authentication. My dovecot version is 2.1.7. My checkpassword is a setuid binary and the mount is a self made fuse-fs. Any ideas what happens? Are there better ways to do this? Thanks, - Jouko
