[Dovecot] [Q] auth(default): plain(?, 11.111.206.99): Username contains disallowed character: 0x20
by JKL 11 Feb '11

Dear all, A new user with Microsoft Express is trying to use IMAP SSL port 993. However they cannot log in. Its only with them. The logs details the following: Feb 11 18:56:03 logout dovecot: auth(default): plain(?,11.111.206.99): Username contains disallowed character: 0x20 Feb 11 18:58:07 logout dovecot: imap-login: Disconnected (auth failed, 1 attempts): method=PLAIN, rip=11.111.206.99, lip=62.58.61.184, TLS: Disconnected I think that the 0x20 is a space. However the user states that they are using this format and that there is no space: user.name(a)test.com Does anyone know where I could start to look for this? Regards,S

[Dovecot] Domain blacklisting
by Thomas Hummel 11 Feb '11

11 Feb '11

Hello, I run dovecot-2/Maildir/LDAP user/passdb and would like to be able to deny acess to users who connect from certain domains/IP (google.com for instance since in that case they gave their credentials to a third party). My understanding is that I cannot use some negative form of "allow_nets". The only mechanism I can think of is tcp_wrappers. However, dovecot documentation mention it only in the dovecot-1 section. Does it work the same way with dovecot-2 ? Is it a bad idea (I'm thinking of the induced overhead) ? Can you see another way to blacklist (at dovecot application level) some sources ? Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

Did something change in doveadm? One of my scripts blew up last night saying that -A is not a valid flag. The -A and -u flags seem to not be working on trunk anymore. # dovecot --version 2.0.9 (723a26a7d328) # doveadm expunge -u matt mailbox Junk savedbefore 31d doveadm(matt): Fatal: Unknown argument MATT (matt of course is the user sending this message on this server) # doveadm -Dv expunge -A mailbox Junk savedbefore 31d doveadm(matt): Debug: Loading modules from directory: /usr/lib/dovecot doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/lib10_quota_plugin.so doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/lib20_expire_plugin.so doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/lib20_zlib_plugin.so doveadm(matt): Debug: Loading modules from directory: /usr/lib/dovecot/doveadm doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_expire_plugin.so doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm(matt): Debug: Module loaded: /usr/lib/dovecot/doveadm/lib10_doveadm_zlib_plugin.so doveadm(matt): Fatal: Unknown argument -A Also with the quota plugin. # doveadm -f tab quota get -A doveadm(matt): Fatal: doveadm quota get: Unknown parameter: -A I can provide a doveconf -n and mySQL config files if needed.

[Dovecot] Separate access to different "folders" of the same mailbox?
by Alexander Chekalin 11 Feb '11

11 Feb '11

Hello Timo and everyone, I think on such an idea that may save me a bit of space and time: in my company we have a mailbox that holds a copy of every message that our SMTP processed. While it eats a lot of space, it saved us several times when, you may imaging, user "suddenly" deleted the most important message in his life and call our IT guys for help. The mailbox contains "folders" for each day (like 2011-02-10), which keeps mailings for that day only. Even with this, it is sometime hard to work with that "keep all" box (basically, it is slow as the size is huge). What I'd like to add is some kind of "virtual folders" (for each of our internal users) that list messages from and to his address. And I'd like to permit every user to see (that is, read only mode) only "his" such a virtual folder in our "keep all" box, so user can see his old messages on his own. Looks like 1) I need an ACL to limit user access to "their" folders and somehow hide other folders at all 2) Have such virtual folders work with huge ammount of mailings (kind of 300 Gb), separated in maybe 1000 folders (per days). I really afraid it will be slo-o-o-ow search, even with indexes (I mean, virtual folder that is defined as search over 1000 folders will be not that fast). The mailbox is maildir by nature. How can I archive these goals with smallest load possible, and if it is possible at all? Thank you, Alexander Chekalin

[Dovecot] xi.rename-it.nl/debian/ dovecot-2.0 sieve problem
by Martin Rozgonski 11 Feb '11

11 Feb '11

Hi, i used to use deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main to update dovecot 1.2 with debian lenny. I used the convert script to change my configuration file. Everything works fine but sieve does not work anymore. There is no error in the logs but dovecot simply ignores any filter. I checked the documentation/configuration twice and had still no success. Maybe, this is a known/unknown bug or any suggestions? Best regards Martin Rozgonski

[Dovecot] multiple domains
by Sergio Moscoso 10 Feb '11

10 Feb '11

Anybody can help me with this issue. It's the right place to submit thios question, please help me. Actually we have configured a server (postfix,dovecot,mysql) with multiple domains, but the problem resides in that we don't want to login via POP3 using "user@domain" just using "user", because we'll migrate our actual platform (Qmail) to dovecot. Our users are logging to their mail boxes, using only user name. We want to ask if that's posible to use a function like a "vipmap" in qmail, that allow to map an IP address to a domain. We're using the dovecot 1.0.7, the configuration shows as follows: login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 100 mail_location: maildir:~/Maildir/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: static args: uid=101 gid=102 home=/home/vmail/%d/%n We'll apreciate your response, 'cause we coulnd't find information about this issuet and we didn't to find any clue that shows how can realize it. Thank you in advance. Sergio Moscoso
