[Dovecot] procmail/formail --> Maildir
by Andre Huebner 04 Dec '07

04 Dec '07

Hello List, i switched mailformat from mbox to maildir. Now i have a little problem with procmail/formail and headermanipulation of mails. Here an example: 0 * ^From.*gmx.de | (formail -t -I"procmail: gmx.de") >> /var/spool/mail/xxxxxx So, i can add some different headerlines for later evaluation and the result is attached to inbox. Now i have the problem that i don't know name of targetfile, cause it is unique for every mail if maildir is used. I did not found a Option or other workaround to solve this case. I know, it is not a dovecot problem but i hope somebody can give a hint. Could it be a possibility to leave all unchanged? Mails could be transported to /var/spool/mail/xxxxxx and picked up by dovecot if in dovecot.conf the convert-plugin ist always activated? Thanks Andre

[Dovecot] v1.1.beta10 released
by Timo Sirainen 03 Dec '07

03 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta10.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta10.tar.gz.sig Changes since beta9: - dotlock_use_excl=yes is now the default. I think this should work in all NFS setups that are in use nowadays. O_EXCL has worked since NFSv3. - fs quota: Added "noenforcing" option - Fixed compiling with non-gcc - Fixed quota plugin crash - Lots of fixes to handling message searches, especially related to non-ASCII searches. And most importantly: It includes the new Squat full text search indexing code. There are a few things left in my TODO for it: - It's currently used only to optimize root level AND searches. So for example SEARCH (OR TEXT hello TEXT world) is still searched the slow way. - Expunged messages are never removed from the indexes. - The index could be updated while messages are being saved, but this isn't done yet. - Indexed substring length is hardcoded to 4 characters. This should be configurable, although I think 4 should work quite nicely. Lucene plugin is probably completely broken now, but it was also in beta9.

[Dovecot] dovecot process nice value
by Daniel Watts 03 Dec '07

03 Dec '07

My imap processes seem to all be running with a nice value of -15 (top priority). Is this usual? Not sure if this is a dovecot setting or something going on with my own system configuration somewhere. I know the userdb query can set the nice value but mine (a mysql query) does not... We're having problems with our mail partition being absolutely thrashed and thought over-strong imap processes might be a factor. Many thanks, Daniel

I'll talk to my boss, but he's - well, to put it politely, its a bit difficult to get money out of him... Actually, I'm looking into some form of file-system level de-duplication, which may negate the need for this... Anyone know of anything available on the cheap/free side? -- Best regards, Charles

[Dovecot] 1.0.8 install trouble on Ubuntu dapper (PAM)
by John Gateley 03 Dec '07

03 Dec '07

Hi, I was running the Ubuntu dovecot package until now, and decided to upgrade because of an issue with Thunderbird. I downloaded and compiled 1.0.8, and it's not starting up. The error I'm getting is: Dec 2 15:35:04 jfootoo dovecot: auth(default): Unknown passdb driver 'pam' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) D I used "./configure" and "./configure --with-pam", both give the same error message. dovecot --build-options gives: uild options: ioloop=poll notify=dnotify ipv6 openssl SQL drivers: Passdb: checkpassword passwd passwd-file shadow Userdb: checkpassword passwd prefetch passwd-file static I have a dovecot that I compiled for a different system and it includes "pam" in the Passdb line. I found a page on the web saying I might need the pam-devel package, but that doesn't seem to exist for ubuntu. I saved the output from ./configure, grepped for pam, and got: checking for pam_start in -lpam... no Any ideas? What do I need to get configure to do pam support? Thanks very much j

Timo Sirainen, on 5/21/2007 8:54 AM, said the following: <snip> > Upcoming v1.1 features, more or less implemented in this order: <snip> Hey Timo, I'm loving all of the new functionality - especially the full support for Shared mailboxes and ACLs... but... I don't see any mention of support for SiS (single-instance-storage) as discussed previously on the list, even for upcoming 1.2/2.0 Did this fall through a crack? Or did you decide it was going to be too difficult for the time being? I'd dearly like to get this working, at least for email attachments... Thanks for your consideration, and thanks so much for dovecot! -- Best regards, Charles

[Dovecot] namespaces, shared mailboxes
by Alexander 'Leo' Bergolth 02 Dec '07

02 Dec '07

Hi! I'd like to provide shared mailboxes with maildir that should appear like 'Shared/<mailboxname>' to the clients. Using the namespace configuration below, everything works fine, exept one thing: Mail clients (only tested with Thunderbird) won't allow to put mails directly in 'Shared/mailboxname' (the folder it is greyed out). You currently have to create subfolders and put the mails in those subfolders. Is there any workaround for this problem? -------------------- 8< -------------------- namespace private { separator = / inbox = yes prefix = location = mbox:~/mail:INBOX=/var/mail/%u } namespace shared { separator = / # hidden = yes prefix = Shared/spamrep/ location = maildir:/var/spool/mail/Shared/spamrep:CONTROL=~/Maildir/control/Shared/spamrep:INDEX=~/Mail\ dir/index/Shared/spamrep } -------------------- 8< -------------------- I'm using dovecot 1.0.8. "Server supports folders that contain subfolders and messages" is enabled in Thunderbird's advanced server settings.
