dovecot 2.2.36 and wforce
by Tobi 13 May '19

13 May '19

Hi list I'm trying to setup dovecot 2.2.36 on a Centos6 to communicate with a wforce daemon on the remote side. wforce is latest released from git repo. Daemon part is working and I can successfully send queries from remote systems to wforce via curl For dovecot I configured in /etc/dovecot/conf.d/95-wforce.conf > auth_policy_server_url = http://REMOTE_IP:8084/ > auth_policy_hash_nonce = my_random > auth_policy_server_api_header = Authorization: Basic <BASE64 of wforce:my_password> > auth_policy_request_attributes = login=%{requested_username} pwhash=%{hashed_password} remote=%{rip} device_id=%{client_id} protocol=%s restarted dovecot without errors, but upon testing via imap I cannot see just one single tcp paket leaving direction REMOTE_IP on port 8084. It looks like auth policy in not involved at all. Thanks for any idea tobi

One more obvious line from the log: dovecot[26621]: auth: Error: LDAP: Connection lost to LDAP server, reconnecting Where it claims to reconnect, but after that there is no LDAP authentication. And the same configuration has worked fine since at least 10 years ago up to some recent update of dovecot or openldap. Best Dag

IMAPSieve message marked as HAM should go through full sieve script of user
by Matthias Fechner 10 May '19

10 May '19

Dear all, I use the IMAPSieve implementation described here: https://wiki.dovecot.org/HowTo/AntispamWithSieve It is working really great! Thanks a lot for this. The problem I have now is: A message was by accident marked by rspamd as spam, so a false-positive and is moved to the Junk folder. If I click in my email program now on `Not Spam` it is learn as HAM but moved to the INBOX. I would like that the email is not moved to INBOX but it should be moved through the sieve script of the user again, as it is a new email. Currently I have to mark all false-positives as not spam and have then to manually move it to the correct subfolder which is a bit annoying. Is this possible? Thanks a lot! -- Gruß Matthias

I am trying to find out if Dovecot supports "smtputf8". Obviously, I am looking in the wrong places, but I just cannot find a definitive answer. Thanks! -- Jerry

doveadm sync issues (revised)
by Sven Strickroth 10 May '19

10 May '19

Hi, I'm experiencing serious issues using doveadm sync; mails are not replicating and/or mails are duplicating. I wanted to use this for migrating external mailboxes to my server (in order to overcome the time when some servers/clients still use the old server and some already my server, as described on <https://wiki2.dovecot.org/Tools/Doveadm/Sync>). Finally I was able to reproduce this with the 2.3 branch (cf. <https://dovecot.org/pipermail/dovecot/2019-April/115600.html>). I'm sorry that I can only test the version 2.3.4.1, but according to the changelog I think this is still an issue with the latest version. I tried to find a few steps in order to replicate this easily: For testing purposes I simulate both the remote and local server on my Dovecot instance. I created remote(a)DOMAIN.TLD and local(a)DOMAIN.TLD accounts and both use mdbox and are empty. First, send two mails to remote(a)DOMAIL.TLD (Subjects: Test1 and Test2). Start backup remote IMAP account (remote(a)DOMAIN.TLD) to local account (local(a)DOMAIN.TLD) $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" backup -R -u local(a)DOMAIN.TLD imapc: Both mailboxes are in sync now (containing Test1 und Test2). Now send two messages to remote(a)DOMAIN.TLD (Subjects Test3 and Test4) and two messages to local(a)DOMAIN.TLD (Subjects Test5 and Test6). Run sync: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: See that syncing fails: remote(a)DOMAIN.TLD contains: Test1,2,3,4,5,6 (as expected) local(a)DOMAIN.TLD contains: Test1,2,5,6,4 (Test3 is missing here) When not using the "-R" parameter it seems to work. Running sync again: $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -u local(a)DOMAIN.TLD imapc: causes messages to duplicate: remote(a)DOMAIN.TLD contains: Test1,2,6,5,4,3,5,6,4,6,5,4,3,5,6 local(a)DOMAIN.TLD contains: Test1,2,5,4,6,4,5,6 (3 is still missing) This is independent of the "-R" parameter. I could also experience this issue when using one-way sync, however, the first one-way sync is still ok, but then messages start duplicating as for the two-way sync without "-R": $ doveadm -o imapc_user="remote(a)DOMAIN.TLD" -o imapc_password="PW" -o imapc_host="localhost" sync -R -1 -u local(a)DOMAIN.TLD imapc: Hope you can replicate this, too, and finally fix the issue. -- Best regards, Sven Strickroth PGP key id F5A9D4C4 @ any key-server

Re: Dovecot does not recognize imported messages

I changed the user permissions, this is a must.

I copied it directly. I didn't use the imap protocol. Dovcot didn't recognize these emails. I didn't display these imported emails on my page, recalculating disk quotas.

Dovecot not surviving OpenLDAP restart
by Dag Nygren 09 May '19

09 May '19

Hi! Running Dovecot 2.2.36 and authenticating against an OpenLDAP 2.4.45 server. Now since some update of dovecot it will not be able to authenticate your logins after a restart of the LDAP service is restarted without a reboot of the dovecot server. Anything new here that I should be aware of? Best Regards Dag

dovecot dict protocol
by Peter Hudec 09 May '19

09 May '19

Hi there is there any written specification for dovecot dict protocol instead of the code? Small example is in docs on https://wiki.dovecot.org/AuthDatabase/Dict and theere is link for all commands/reply in the code https://wiki.dovecot.org/AuthDatabase/Dict I’m writing small dict server and need some explanation for CMD: I, what does the flags means and how should the result looks like CMD: D, I thing this is the same as C, but coud be done later /async/ The reply codes are not very clear. I understand O, N, F. The rest is strange to me. Maybe this is good question do devel mailing list. regards Peter
