Changes to userdb not picked up
by Tom Sommer 08 Feb '17

08 Feb '17

I have my quota limits stored in userdb and auth_cache enabled (default settings). When I change the quota limit the old limit is still cached for the user for another hour. Is there any way to prevent this from happening? Thanks -- Tom

Hi list, where can I find the meaning of lowercase file flags ? I found this information: http://cr.yp.to/proto/maildir.html <http://cr.yp.to/proto/maildir.html> But what does the lowercase a & d mean as in ...,S=2364,W=2411:2,Sad ? Thanx for your help !

Sieve LDA Errors (Improper Saving?)
by Richard Laager 08 Feb '17

08 Feb '17

I'm getting lots of errors like this (possibly on every message delivery): imap2 dovecot: lmtp(rlaager(a)wiktel.com): Error: OU02K+gQmFhUAwAAVtfydQ : sieve: binary save: failed to create temporary file: open(/var/lib/dovecot/sieve/junk-mail.svbin.ima p2.852.) failed: Permission denied (euid=500(vmail) egid=500(vmail) missing +w perm: /var/lib/dovecot/ sieve, dir owned by 0:0 mode=0755) imap2 dovecot: lmtp(rlaager(a)wiktel.com): Error: OU02K+gQmFhUAwAAVtfydQ: sieve: The LDA Sieve plugin does not have permission to save global Sieve script binaries; global Sieve scripts like `/var/lib/dovecot/sieve/junk-mail.sieve' need to be pre-compiled using the sievec tool It's intentional in my setup that the vmail user can't write to the global sieve script directory. But it shouldn't need to, as those are already pre-compiled: rlaager@imap2:/var/lib/dovecot/sieve$ ls -la total 12 drwxr-xr-x 2 root root 4096 Nov 29 22:27 . drwxr-xr-x 3 root root 4096 Feb 6 20:39 .. lrwxrwxrwx 1 root root 53 Sep 12 01:35 junk-mail.sieve -> /usr/share/wiktel-server-mail-backend/junk-mail.sieve -rw-r--r-- 1 root root 254 Nov 29 22:27 junk-mail.svbin rlaager@imap2:/var/lib/dovecot/sieve$ ls -la /usr/share/wiktel-server-mail-backend/junk-mail.sieve -rw-r--r-- 1 root root 124 Oct 31 09:34 /usr/share/wiktel-server-mail-backend/junk-mail.sieve Note that the .svbin is from November, while the text version is from October. Even if something is looking at the date of the symlink, that's from September. So the first question is... why is Dovecot trying to write the binary file? I dug into the Pigeonhole code... I think, but am certainly not sure, that lda_sieve_open() in pigeonhole/src/plugins/lda-sieve/lda-sieve-plugin.c is the relevant function calling lda_sieve_binary_save(). At the end of the function, it has: if (!recompile) lda_sieve_binary_save(srctx, sbin, script); This seems odd to me. Why is it trying to save in the "!recompile" case? It seems like it should be saving in the "recompile" case. If I'm reading this code right, recompile is set when it loads a corrupt sieve binary script and needs to recompile from text. I could be completely off, though. Any thoughts? -- Richard

Migrating to sieve
by Adam Shostack 08 Feb '17

08 Feb '17

Hi, As I migrate to sieve, I would like to carry over the logic I had in procmail rules, which let me take all mail where I'd never sent email to that address into a final spam catchall, which I called "neversent." I see that sieve can't run external programs, and I wonder if that means I'm SOL, or is there an alternate approach that does roughly the same thing? (I understand the general security logic for that decision. I have root access on the server in question if that helps.) Thank you for any help you can provide! Adam The procmail code was: # a bunch of complex shell script to extract From: into a variable of that # name. :0: * ^TO_$ME * !? fgrep -q --ignore-case -e "$FROM" $HOME/.lbdb/m_inmail.list neversent along with a procmail-outbound setup of: :0hc | lbdb-fetchaddr -a :0 ! "$@"

Dsync migration with shared folders
by George Dimakopoulos 06 Feb '17

Hi everyone, We discovered that the migration path from a VPS to our 2XHP replication server environment with shared folders should be: 1) Rsync all domains from the VPS to serverA. Then rsync all domains from ServerA to ServerB. ServerA & ServerB are in a identical state. 2) Create an empty directory for the shared indexes 3) Start dovecot on both machines. If we did not sync both machines then dsync could not replicate the domains that contained shared folders. What is the right migration process for domains with shared folders ?
