[Dovecot] Editing sieve files
by jalal 02 Aug '07

02 Aug '07

Hi all I've got a standard dovecot setup: home is /var/spool/vmail/domain/user/ uid: vmail gid: vmail Sieve file is: /var/spool/vmail/domain/user/.dovecot.sieve if i want to change the dovecot-sieve file to modify the rules (or even let my users do it at some point) then it has to been done by root. Is there a way to setup the sieve plugin so a user can create his own rules? sort of like ~/.procmailrc TIA jalal

[Dovecot] v1.0.3 released
by Timo Sirainen 02 Aug '07

02 Aug '07

http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.3.tar.gz.sig - deliver: v1.0.2's bounce fix caused message to be always saved to INBOX even if Sieve script had discard, reject or redirect commands. - LDAP: auth_bind=yes and empty auth_bind_userdn leaked memory - ACL plugin: If user was given i (insert) right for a mailbox, but not all s/t/w (seen, deleted, other flags) rights, COPY and APPEND commands weren't supposed to allow saving those flags. This is technically a security fix, but it's unlikely this caused problems for anyone. - ACL plugin: i (insert) right didn't work unless user was also given l (lookup) right. - Solaris: Fixed filesystem quota for autofs mounts.

[Dovecot] migrating users
by Pete McEvoy 02 Aug '07

Hi. I've been migrating users from mbox to maildir on a new server running dovecot 1.0 - is there any method I can employ to prevent my pop3 users having to redownload mails after I move them? Thanks -- Pete

[Dovecot] Shared mailboxes v1.0.3

Dovecot still creates cur, tmp, and new in /home/mail/public (or applicable, as configured). Doesn't hurt anything but just wanted to make the point. > http://wiki.dovecot.org/SharedMailboxes B.

Re: [Dovecot] Missing MIME-Version header in e-mails.

Probably something like this, although I haven't tried it... src/lib-mail/message-parser.c @225: - if (!hdr->eoh && strcasecmp(hdr->name, "Mime-Version") == 0) { + //if (!hdr->eoh && strcasecmp(hdr->name, "Mime-Version") == 0) { /* it's MIME.

[Dovecot] mbox inbox default
by bhayden＠umn.edu 01 Aug '07

01 Aug '07

HI Timo & all. We're an mbox environment, inboxes in /var/mail/$USER (I'll include dovecot -n output at the bottom of this mail). mail_location is set accordingly for deliver. I'd assumed that if the /var/mail/$USER file doesn't exist, dovecot would create it, but we've discovered from experience (and I verified it in mbox-storage.c) that if access(path, R_OK|W_OK) fails--as it does if the file doesn't exist--that dovecot defaults then to delivering in root_dir/inbox. I'm curious why this is. It seems like if the configured INBOX file doesn't exist, dovecot should create it if possible; it's a different case than if, say, the user doesn't have write access to that directory, in which case it of course would be appropriate to fall back to some other location rather than rejecting mail. Is there something I'm missing that makes my idea wrong?

[Dovecot] High cpu usage OpenSolaris
by Gary Gendel 01 Aug '07

01 Aug '07

All, Nevermind... I discovered the problem. It was in the Solaris Sun Studio 12 compiler. I created a debug version to begin testing, but that version worked without sucking up the cpu. So it looks like the optimizer messed up. If I used the -fast optimization, it sucks up cpu, but with -xO5 all is well. Gary --------------------------------------------------------------------- Hi, I've built 64-bit dovecot 1.0.2 on Opensolaris to replace version 1.0.0rc10. It functions fine, but when I connect, it eats up all available cpu. My guess is that the poll thread is running continuously. Any ideas on what I should do to verify this or does anyone know of a fix? Thanks, Gary

[Dovecot] RFE: please include quota waning patch
by Farkas Levente 01 Aug '07

01 Aug '07

hi, it'd be very useful to include the quota warning patch in official release. without it the quota support is not really useful since mail simple dropped when quota is over. and most enduser never know what happend, they just recognize mails are not coming:-( thanks. -- Levente "Si vis pacem para bellum!"

[Dovecot] Missing MIME-Version header in e-mails.
by Tan Shao Yi 01 Aug '07

01 Aug '07

Hi, I notice that in src/lib-mail/message-parser.c, there is a section of code that checks for the presence of MIME-Version before allowing processing of the Content-* headers. Is there a possibility of relaxing this rule? There are some broken mailers, in particular newsletter mailers that do not seem to honour the MIME-Version header, though they do send the Content-Type. Cheers.

[Dovecot] Mount options and NFS: just checking...
by Mike Brudenell 01 Aug '07

01 Aug '07

Greetings - I'm now in the last couple of weeks before going live with Dovecot (v1.0.3) on our revamped IMAP service. I'd like to double-check about the best mount options to use; could someone advise, please? I have three separate directory trees for the message store, the control files and the index files. These are arranged as follows: Message Store Mounted over NFS from a NetApp filer; filestore quotas are ENABLED. Control Files Mounted over NFS from the NetApp filer; filestore quotas are DISABLED. Index Files Mounted on local disk; filestore quotas are DISABLED. We will have a pair of Solaris 10 servers on which Dovecot 1.0.3 is running. Users are normally directed to their "preferred" server but, if it is unavailable, will go via the other server. Q1. Am I right in thinking that for the Message Store and Control Files I should NFS-mount both of them with the "actimeo=0"? (Or would "noac" be better, which also turns off client write- caching as well as the attribute cache?) Q2. Should I NFS-mount either or both of the Message Store and Control Files with the "noxattr" option to turn off extended attributes? Q3. Which of the filestores should I mount with the "noatime" option? (I understand that for the filer-based NFS mounts this can be done on the filer, as the option isn't available with "mount" for NFS-monted filestores.) Q4. Any other options to use/miss out? Currently my understanding from the list and the NFS page at the Wiki is: A1. Use "actimeo=0" for both Message Store and Control Files. No idea about the need for/impact of using "noac". A2. No idea. A3. Safe to use "noatime" for all three filestores. (I understand Dovecot will use utime() when needed on such filestores, but am not sure if it will work on the NFS-mounted filestores from the filer if access times are turned off at the filer end.) Any thoughts, please?
