Save user passwords in clear text
by Lefteris Tsintjelis 13 Aug '16

Is it possible to save user passwords as clear text through dovecot? I am currently using MD5 passwords and I allow only "plain and login” mechanisms but I want to switch my database to clear text as this will give me the ability to use more mechanisms such as CRAM-MD5. Is this possible? Thank you

Sieve with many criteria

Hi, currently I am putting all my filter strings into a big array in my sieve script. I wonder whether this is the best way to store many criteria. Any suggestions? -- Cheers, \\|// Vince (o o) ----------------------------ooO-(_)-Ooo------------------------- ''' (o)_(o) [ ][0][ ] ô¿ô (=°o°=) World Domination by Copy and Paste [ ][ ][0] - (")_(") [0][0][0] () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments Ooo. ---------------------------.ooO----( )------------------------- ( ) (_/ \_)

receiving and associating emails to single a/c
by David Tildesley 13 Aug '16

13 Aug '16

Hi,Looking for advice.Scenario: we have a dmz mta that currently redirects received emails for a selection of email domains to specific internal ms exchange servers. We want this mta to redirect incoming customer emails directed to a set of email addresses numbering about 30, to a dovecot server and associate these emails to a single dovecot user account so that a contact Centre platform can pull these emails on a frequent cycle.How to go about configuring this on the dovecot? I assume a postfix server needs to be installed on the dovecot server for the dmz mta to send these emails to dovecot inbox? Any advice most appreciated. David. Sent from Yahoo Mail on Android

Dovecot Director self ip
by Tomaž 12 Aug '16

12 Aug '16

Hello everybody! I kindly ask somebody to help me with this problem. I'm trying to configure Dovecot proxy with Director. On the same machine is KeepAlived that needs this configured to bind non local IP: sysctl net.ipv4.ip_nonlocal_bind=1 But as already mentioned in this email: http://www.dovecot.org/list/dovecot/2012-November/087033.html Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is set, everything works ok, but we break keepalived) because otherwise the second server uses IP from the first server as "self". Is it possible to configure this some other way, so Dovecot Director doesn't try to bind to all IPs and because of above configuration, uses the first one that binds. This is the result from director status on server 1: root@u1:~# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never handshaking and server 2: root@u2:/var/log# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never My dovecot config: http://pastebin.com/RnmHRWhY Thank you very much!

dovecot 2.2.25 & deleting emails from \Junk special-use assigned folder
by Marc Jauvin 11 Aug '16

11 Aug '16

Since our cPanel installation upgraded Dovecot from 2.2.23 to 2.2.25, deleting emails located in the Junk folder (\Junk special-use), the emails end-up in the \Trash special-use folder instead of being purged as before. Is there something that changed or this some configuration I am missing? Thanks for any help regarding this. -- Marc Jauvin Register4less, Inc. 514-905-6500 x403

I have a ton of these errors in my logs: Aug 11 14:16:04 imap(xxxx(a)xxxxx.xxxx): Error: Corrupted index file...../dovecot.list.index: Header's corrupted flag is set Does Dovecot not automatically fix these? Or what is the correct action to take? -- Tom

Replication issue EOF or unknown flag V

Hi, I'm trying to sort out a replication error: It was working initially, but now it no longer works. Dovecot 2.2.25, Maildir format Delivering via LMTP. If I run doveadm replicator replicate rick(a)havokmon.com On the 'master' side I see : Aug 09 14:02:17 dsync-server(rick(a)havokmon.com): Error: read(172.16.1.86) failed: EOF (version not received) Aug 09 14:02:17 dsync-local(rick(a)havokmon.com): Error: read(172.16.1.86) failed: EOF (version not received) On the 'slave' side I see: Aug 09 14:02:10 doveadm(172.16.1.81,rick(a)havokmon.com): Error: doveadm client: Unknown flag: V Aug 09 14:02:17 doveadm(172.16.1.81,rick(a)havokmon.com): Error: doveadm client: Unknown flag: V This seems to just happen with my mailbox, so I've completely removed it on both sides, to no avail. My mailbox was re-created on the slave side, but nothing else has occurred (no folders or new mail). #doveadm user rick(a)havokmon.com field value uid 89 gid 89 home /home/prime/domains/havokmon.com/rick mail maildir:/home/prime/domains/havokmon.com/rick/Maildir/ host 172.16.1.81 proxy_maybe Y mail_home /home/prime/domains/havokmon.com/rick mail_location maildir:/home/prime/domains/havokmon.com/rick/Maildir/ Any thoughts?

custom mail_location detection for dovecot lda
by Alexander 'Leo' Bergolth 09 Aug '16

09 Aug '16

Hi! Is it possible to do something like "post-login scripting" to detect and set a per-user custom mail location for dovecot LDA delivery? I tried to use a wrapper-script around dovecot-lda that sets the environment variables MAIL="..." and USERDB_KEYS="MAIL" just like overriding userdb fields may be done using imap postlogin scripts, but unfortunately this doesn't seem to be honored. (Also tried with dovecot-lda -k.) Woud be very useful for slow migration from one mailbox format to another. Is there any other way to supply a custom mail_location to dovecot-lda?
