Re: [Dovecot] Upgraded to Dovecot-1.2.16 and Sieve-1.1.8 but Still No Sieve Parameters

So I have to manually put in the parameters in the dovecot.conf file? I assumed that they would have been added to the dovecot-example.conf file once I installed Sieve. Am I correct?

[Dovecot] Solaris 10 Compilation Issue with 2.0.12 (actually post 12690) [WORKAROUND PROVIDED]
by Peter Bray 13 Apr '11

13 Apr '11

Greetings, Post 12689:7f5735ab7c35 / 12690:02829f7f79c7 dovecot uses the reentrant version of get(password/group)* related functions. There are two variants of these functions on Solaris. To get the variant used by dovecot code based you need to define _POSIX_PTHREAD_SEMANTICS (see attached manual page). Initially I defined this just for the compilation of lib/src/ipwd.c, and got the code to compile / check / run successfully in my environment. After this worked I decided to try compiling the whole code base with CPPFLAGS="-D_POSIX_PTHREAD_SEMANTICS" ./configure .... This also seems to work fine. My environment uses IMAPS (X86) and Proxying IMAPS (SPARC). All code compiles / checks / runs (only 64-bit versions run tested) with the above CPPFLAGS modification on Oracle Solaris 10 Update 9 (both 32/64 bit on both X86 / SPARC with GCC 4.1.2) systems. Regards, Peter Bray Sydney, Australia PS: I have not investigated an appropriate way to modified configure.in to make this addition automatic.

Multiple > deliveries are useful only if you want to try to get the same mail file > hard linked to all recipients. So normally this is a non-issue. I guess my sendmail is not normal. The default configuration does pool multiple recipient delivery and run mail.local with all these users as arguments in one invocation. dovecot-lda doesn't seem to support multiple recipients per invocation, so this won't be a problem. The implication for sendmail users, though, is that multiple concurrent deliveries must be disabled if you use dovecot-lda (the 'm' flag must be removed from LOCAL_MAILER_FLAGS) as implicitely done in http://wiki2.dovecot.org/LDA/Sendmail I notice the 'A' flag is missing here: doesn't this kill aliasing?

Ah. I'll take your word for it since I only have the SysV stuff installed. Thanks for the info. Joseph Tam <jtam.home(a)gmail.com>

Greetings. Im about to move from mbox to Maildir++ and change the deliver method from procmail. I have less than 100 accounts, but there's a lot of mail (around 16GB) Apart from the documentation on Dovecot's site, anyone has good recommendations, and, if you have experience doing this migration any tips? Thanks for any info, and wishing you all a nice week -- ------------------------------------ Julio C. Ortega ONUVA http://www.onuva.com

I have upgraded to a newer version of Dovecot and I have installed Sieve. Everything went smooth and with no errors but I still don't see any Sieve parameters in dovecot.conf file. I'm looking at /usr/local/etc/dovecot-example.conf. What could be the issue? Thanks -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Questions about converting maildir to mdbox.
by Henrique Fernandes 12 Apr '11

12 Apr '11

First of all i would like to thanks Timo for the excellent job done in dovecot. We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using. So lets begin: We are using dovecot 2.0.6 with maildir in an ocfs2 partiton. It is pretty slow access in peak time, but it is related to ocfs2 as i said before, i am trying to mimimize the ocfs2 latancy by using mdbox. Another problem that we have are Full backup that takes about 24h and incremental takes about 13h I am thinking in converting some email for testing propose, but i am wondoring how would dovecot convert this, like if i convert all mail from maildir to mdbox it would make many mailbox based on this seetings ? Or in the first convert it would make a big mdbox file and after it it will rotate by day or it would make many boxes just based on size? mdbox_rotate_size = 5m mdbox_rotate_interval = 1d Well, another thing can i make rotate interval happens in a certain time of day? end from where it takes this time ? it rotates at midnight ? Another one!, if i lose the index files what really happens ? Sometimes in my server the index get corrupet and as i am reading mdbox index files held information that is not in other place. So what should i do to prevent any possible lose of data even if i lose the indexes? I was reading about backup restore also, but i did not get it pretty well. With maildir we simple restore the files and the index gets rebuilt! What should i do with mdbox ? Restore the files and the index ? But how about the other emails that the account got after the backup, how i should merge the multiple files and more importanet how do i merge the index files ? Well, sorry about my english! And Thanks alot guys! []'sf.rique

[Dovecot] Vpopmail and lastauth
by mailing＠securitylabs.it 12 Apr '11

12 Apr '11

Hello, I'm migrating many accounts to a new server with vpopmail 5.4.33 and dovecot 2.0.11. I've already vpopmail 5.4.32 and dovecot 1.2.16 on others servers running without problems. With dovecot 2.0.11 my lastauth file is not updated. This file usually is update on any access (smtp, pop3, imap) with the client's IP, for every mailbox. Now it's updated only when a client authenticate itself via SMTP (smtp-auth with qmail + vpopmail), and not with imap/pop3 access.
