Dovecot LMTP Proxy + STARTTLS?
by Tobi 27 Nov '17

27 Nov '17

Hi I got dovecot 2.2.26 on a Centos7 with latest updates. Dovecot is configured to act as director and delivers to my two backend servers. I enabled lmtp proxy on director to listen on port 24. Now I see in msg headers that the connection to the lmtp proxy uses STARTTLS but the connection from proxy to backend seems to be unencrypted. Is it possible to enforce the use of STARTTLS in the connection from the director to the backend as well? Regards tobi

doveadm backup or sync Read status
by DurgaPrasad - DatasoftComnet 26 Nov '17

26 Nov '17

Hello all, I am trying to migrate mail from a dovecot-2.0.13-1_129.el5 maildir to dovecot-2.2.10-8.el7.x86_64 centos 7 mdbox. I am using this command doveadm -v -o mail_fsync=never backup -R -u user(a)domain.com imapc: also tried doveadm -v -o mail_fsync=never sync -1 -R -u user(a)domain.com imapc: Both work flawlessly - Timo is great !!! - My issue is the source folders are all marked as read. The target folders of-course have unread OK. POP3 UIDLs are also ok (tested for one user). (1) My question is how can I make the source remain same (unread status etc.) so that I do migrate the various domains in a transparent manner and then switch servers ?. I have multiple virtual domains. (2) One more question do I have to do both imapc_ & also pop3c_ migration since I need the POP UIDLs to work properly for my outlook POP3 users after migration ?. Thanks DP --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Mark message as read when moved to Trash
by Felix Rubio Dalmau 26 Nov '17

26 Nov '17

Hi all, When I send a message to trash, without previously reading it (just with the subject is enough to say I do not want to read it), it remains as "unread". Then, clients (I am using Kmail) report there are unread message, when all of them are in Trash. The question, then is: Is there any way to automatically mark a message as read, when that message is moved to Trash? Thank you! Felix

Are you sure your mail client doesn't have any rules of its own that may be doing this? Regards, Stephan.

No, is that something that would make a difference between 2.2.15 and 2.2.32? --Mark On Fri, 24 Nov 2017 21:37:47 -0800 Gary <lists(a)lazygranch.com> wrote: > Out of curiosity, do you do a !SSLv3 in the conf file? > > > Original Message >> From: mfoley(a)ohprs.org >> Sent: November 24, 2017 9:04 PM >> To: dovecot(a)dovecot.org >> Subject: Upgrade to 2.2.32 from 2.2.15 failed >> >> I have a problem.

set parameter per user
by A. Schulze 24 Nov '17

24 Nov '17

Hello, My dovecot server (2.2.33.2) work with "lmtp_save_to_detail_mailbox = no" Now I would like to enable the feature for /some/ users. Is that an option that could be set from an LDAP entry? I tried the following: modify my ldap schema to allow an optional attribute "lmtp-save-to-detail-mailbox" in /etc/dovecot/ldap.conf user_attrs = ... =lmtp_save_to_detail_mailbox=%{ldap:lmtp-save-to-detail-mailbox:no}, =... Now I set an ldapattribute "lmtp-save-to-detail-mailbox" with value "yes" for some users. Unfortunately messages to user+extension@domain are still delivered to INBOX/ while they should be delivered to INBOX/extension. I also tried to make the attribute accessible vi pass_attr and userdb_foo = ... because I use prefetch driver as userdb. I also disabled prefetching at all but no luck :-/ any Ideas? Andreas

Passing information from passdb to userdb
by Qmail 23 Nov '17

23 Nov '17

I'm trying to hack together a new authentication back-end and I wanted to know if it's possible to pass values from passdb to userdb in the auth_request structure at authentication time. I modified struct auth_request in auth-request.h to contain a new variable and it gets set properly in my passdb, however the value is not there when checking for it userdb. I'm very novice when it comes to Dovecot programming so any help is appreciated. Thanks!
