[Dovecot] Multiple SSL certs question
by Jean-Baptiste Vignaud 29 Oct '09

29 Oct '09

Hello; I was reading the message "how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?", and i was wondering if Dovecot could support the SNI extention of TLS ? SNI is Server Name Indication where during the TLS negotiation, the client set the name of the server it tries to reach I dont know if any imap/pop client support this yet, but this would be a great feature for one IP/multiple virtual domains. Each SNI client would have the correct certificate and not the "main/generic' one. It seems that mutt has a patch for that http://www.mail-archive.com/mutt-dev@mutt.org/msg05251.html

[Dovecot] Hundreds of auth-worker sockets in /etc/dovecot
by Eggert Ehmke 28 Oct '09

28 Oct '09

I run dovecot 1.2.6, before last update I had 1.2.2. on Debian Lenny. I noticed that my config directory /etc/dovecot is filled up with hundreds of old auth-worker.12345 sockets. I guess they should have been cleaned up, is there a misconfiguration? When I remember right, this did not happen with dovecot 1.1.

[Dovecot] listing available subscriptions - shared mailboxes
by Hendrik Pahl 28 Oct '09

28 Oct '09

hi everybody, got a strange issue with 1.2.4 on SLES11. When listing the user's available subscriptions with any client, every shared mailbox that can be subscribed is listed twice, once with it's correct name, 'folder' for example. the second appereance is without the last letter of the name, 'folde' for example. strange behaviour, since this happens with any client. i hope somebody know what is wrong here. thanks in advance, hendrik -- LWsystems GmbH & Co.

Hello all, I use dovecot11-1.1.7-1.4.1 with OpenSuse 11.1. Everything works fine, except the vacation with managesieve. When i send a mail to an address with vacation, i recieve back a vacation message, but i read an error like this into dovecot-deliver.log: Error: file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory And then the vacation is send any time, without limits. I think the problem is dovecot can't find home directory for the mail to write the .dovecot.lda-dupes, but i don't know how to specify that.

[Dovecot] Sieve vacation with russian subject
by Nikita Koshikov 28 Oct '09

28 Oct '09

Hello list, I have noticed that sieve vacation action breaks some non-english letters in the subject. I tested with russian language, if subject contains letters from specific diapason russian alphabet, the message received with unreadable subject, but text in the body with the same letters looks ok. Here is example of full subject header, it contains russian alphabet: Subject: абвгде�?жзийклмноп�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�? Maybe this headers will be usefull: MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit .dovecot.sieve file looks correct, here is it: require ["vacation"]; # rule:[test] if anyof (true) { vacation :days 1 :addresses ["user(a)domain.com"] :subject "абвгдеёжзийклмнопрстуфхцчшщъыьэюя" text: Тестовое русское сообщение(Test russian message). ; } I'm running dovecot-1.1.16 with dovecot-sieve-1.1.6 and managesieve-0.10.6. Please tell, is it possible to fix this ?

[Dovecot] antispam-plugin 1.2 and trailing carriage-returns
by Karsten Bräckelmann 28 Oct '09

28 Oct '09

Guys, Dovecot 1.0.15 [1], just built the latest antispam-plugin 1.2 (tarball) for testing, mailtrain backend for SA integration. Both built from custom spec files. The mail that is being trained is different than its respective source in the mbox file. The trained one shows added, trailing carriage-return chars for all headers, which are not in the headers in the mbox file. This breaks sa-learn -- both these variations are different, and SA would learn *both* when run against each one separately. How comes? Any insight? How could I fix this, other than wrapping the sa-learn inside another shell script and have sed strip off the noise? This becomes more of an issue, once I switch from sa-learn to the lightning-fast spamc training variant. TIA guenther [1] Yes, I know, sorry. Don't want to change everything at the same time, and the target system I'm experimenting for runs that version, too. -- char *t="\10pse\0r\0dtu\0.@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}

[Dovecot] Dovecot, Shared Mailboxes (via symlink), and ACLs
by Dave 28 Oct '09

28 Oct '09

Hello! I just joined the list and will be happy to help where I can in my limited experience, but also come to the table with a question. I think there's something I'm missing regarding shared mailboxes and ACLs, so I will describe my situation and see if I am understanding correctly (running Dovecot 1.1.10). I have read over the Dovecot Wiki many times and have scoured many forums but still can't seem to find a solution. I have an IMAP mailbox that is working fine (user imapuser), so the maildir and related structure is in: /home/imapuser/Maildir I have another IMAP mailbox for another imap user, newuser1, also working fine, with maildir and related structure in: /home/newuser1/Maildir I have created a symlink under newuser1's Maildir to imapuser's Maildir so as to give newuser1 access to the things in imapusers's inbox. I have also symlinked inside the newuser1 Maildir to a folder under imapusers's inbox, let's call it "MailingList", basically settiing up something like: /home/newuser1/Maildir: cur/ .imapuserinbox -> /home/imapuser/Maildir .imapusermailinglist -> /home/imapuser/Maildir/MailingList new/ tmp/ (... and various other Dovecot-related files, nothing ACL related.) Now, I have gotten the shared boxes to work IF I changed the permissions to be rwx for user and group on /home/imapuser/Maildir/*, but this makes procmail (and .procmailrc) unhappy and it starts sending things to mbox files (old system) instead of sending them on to the Maildir. So that doesn't seem to work. Which led me to ACLs. Now, I've tried (after enabling the two appropriate lines in dovecot.conf and restarting dovecot, etc) both per-directory ACL files and global ACLs, and while I can get some things to *change* as viewed by my mail client, I can't seem to create consistent behavior. I know that's fairly vague, but it's like I'll change something in the global ACL and folders are affected that I wouldn't anticipate, based on what I'm understanding of ACLs. So, in the example above, if I enable global ACLs, what names do I use to refer to those shared boxes I'm trying to access? Do I use the link name I made, .imapuserinbox or .imapusermailinglist (without leading periods), like /etc/dovecot/acls/imapuserinbox, or is it based off of the original dir name? Like do I need something like /etc/dovecot/acls/MailingList ? What about the "inbox" I'm sharing in /home/imapuser/Maildir, how do I reference that? Is there a way to do it without affecting or changing permissions of other IMAP users and inboxes on the same system? One thing I am receiving consistently in the error logs is: mail dovecot: IMAP(newuser1): stat(/home/newuser1/Maildir/.imapuserinbox/tmp) failed: Permission denied (euid=152(newuser1) egid=100(usergroup) UNIX perms seem ok, ACL problem?) So it seems if I get the ACL stuff right, I will be in business. Any ideas?? Thanks for any help anyone can give!! Dave
