[Dovecot] Multiple mailboxes per user
by spam＠wilysloth.com 13 Oct '08

13 Oct '08

My users currently have mail delivered to mulitple MailDir locations via procmail. ~/mail/inbox/ ~/mail/graph/ ~/mail/spam/ I would like all these mailboxes to be exported via dovecot IMAP and appear as folders. However, I can't anything beyond the INBOX working. My approach is via 'namespaces'. My config file is changed thusly: $ sudo dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/mail/inbox namespace: type: private inbox: yes namespace: type: private prefix: graph location: maildir:~/mail/graph namespace: type: private prefix: spam location: maildir:~/mail/spam auth default: passdb: driver: pam userdb: driver: passwd I try connecting with mutt and I can see the mails in 'inbox' just fine. I can also see (in the mutt browser) 'graph' and 'spam' just fine too: y:Exit c:Chdir m:Mask ?:Help 1 IMAP INBOX 2 IMAP graph. 3 IMAP spam. However, selecting 'graph' I see: y:Exit c:Chdir m:Mask ?:Help 1 IMAP ../ ...I would have expected it to open the 'graph' MailDir mailbox and display the mail. I try connecting directly using 'mutt -f imaps://user@computer/graph' and I see 'Invalid mailbox name'. telnet-ing in: $ nc localhost 143 * OK Dovecot ready. a1 login user password a1 OK Logged in. c1 list "" * * LIST (\HasNoChildren) "." "INBOX" * LIST (\Noselect \HasChildren) "." "graph" * LIST (\Noselect \HasChildren) "." "spam" c1 OK List completed. a100 logout * BYE Logging out a100 OK Logout completed. The logs only show: Oct 13 10:44:44 machine dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=127.0.1.1, lip=127.0.1.1, TLS Oct 13 10:44:46 machine dovecot: IMAP(user): Disconnected: Logged out Any ideas where I am going wrong? Outlook Express also lists the 'graph' and 'spam' folder but won't show their contents. WS

[Dovecot] Unkown namespace / sieve
by ML 13 Oct '08

13 Oct '08

Hello, I use dovecot + dspam and a very simple global sieve script : require "fileinto"; if header :contains "X-DSPAM-Result" "Spam" { fileinto "SPAM"; stop; } with dovecot 1.0 all run fine, but moving to 1.1 I experience this in maillog : Oct 13 10:31:52 h8h1 deliver(ml(a)sd2i.com): msgid=<8a24c15885037554724ff966f5458592(a)newsletter.RedSquare.com.au >: save failed to SPAM: Unknown namespace Oct 13 10:31:52 h8h1 deliver(ml(a)sd2i.com): sieve runtime error: Fileinto: Generic Error Oct 13 10:31:52 h8h1 deliver(ml(a)sd2i.com): sieve_execute_bytecode(/usr/ local/mail/.dovecot.sievec) failed Oct 13 10:31:53 h8h1 deliver(ml(a)sd2i.com): msgid=<8a24c15885037554724ff966f5458592(a)newsletter.RedSquare.com.au >: saved mail to INBOX Ay idea ? another question : I use virtual users only, they all have a quota_rule from mysql with different quota size, but I put a quota_rule2 globally to ignore Trash since the ignore= doesn't work anymore with 1.1, is that valid or do I need to add the quota_rule2 to mysql results too ?

[Dovecot] client certs with godaddy ssl cert
by Harondel J. Sibble 13 Oct '08

13 Oct '08

I've read the client ssl cert section in the wiki and it talks about using a self signed cert, if I am using a commercial cert, in this case godaddy, how do I implement a self signed cert for the client side and have dovecot make use of this? I know the mechanics of setting up the self signed ca, the question is more what configuration changes do I need to make in dovecot to handle both godaddy and the self signed ca functionality?

[Dovecot] Can I translate the userid to match the UW-POP3 server?
by Albert E. Whale 12 Oct '08

12 Oct '08

OK, I have been running the UW-POP3 server which currently translates all login ids as lowercase (i.e. Anthony becomes anthony). Now the Dovecot server is very flexible and currently I have not found how to translate the upper case characters to lowercase. What configuration setting will translate the userids to lowercase? -- Albert E.

[Dovecot] Different authentication for pop3 and imap
by sh1ny 12 Oct '08

12 Oct '08

Is it possible to run different authentications for pop3 and imap ? What i need is to give access to some clients to pop3 only and to other to imap only. I'm using postgres as a backend. What i actually need is 2 separate queries for userdb, one to select with "WHERE imap_access = 1" and the other one with "WHERE pop3_access = 1" ( that's just an example ). I'm using 1.1.2 but i plan on upgrading to either 1.1.4 or 1.2.

[Dovecot] Password scheme module thoughts?
by Ian R. Justman 11 Oct '08

11 Oct '08

Hi, all. I have successfully deployed the code I wrote to handle Post.Office password hashes. However, I had to implement it as a hack to password-scheme.c. I'd like to implement it as a module so I don't have to hack Dovecot whenever a new release comes out. However, I had a few thoughts: 1. I used Dovecot's own MD5 routines in my implementation because I know how they behave. However, would it make sense to distribute the C sources for the MD5 routines, or would it make far more sense to have a Dovecot build tree already (so I can use Dovecot's function library)? 2. Is there good documentation for Dovecot's plugin API? I need it so I can figure out how to write the parts which the main program call so then the code can be used as a plugin. Thanks! --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

[Dovecot] sieve multi-line parser bug
by info 10 Oct '08

10 Oct '08

Dear sirs Thank you and congratulations for creating Dovecot. When a message header is split along several lines, it seems only the first one is parsed by sieve. The following header: From: "=?iso-8859-1?Q?Cotiatododia=20-=20O=20Jornal=20de=20Not=EDcias=20a=20Se?= =?iso-8859-1?Q?rvi=E7o=20de=20Cotia=20e=20Regi=E3o=2E?=" <newsletter(a)cotiatododia.com.br> was not discarded by the following rule (when it should have been due to "cotiatododia"): if anyof (header :contains ["From", "Reply-To", "To", "Cc"] ["cotiatododia", "ganhedinheiro.com", "1000deaths.com", "ione.correia", "nsbezerra", "estudenoexterior.com", "pestana(a)mauriciopestana.com.br", "institutojairmoura2(a)gmail.com", "webmaster(a)ie.org.br", "jahgor(a)jahgor.com.br", "marketing(a)mirostur.com.br"], header :contains "Subject" "E ai!, Essa voce Tem que Ver!") { discard; } Thank you, Dennis
