Sieve: Avoiding duplicates in a folder while keeping in Inbox
by Nick Urbanik 13 May '24

13 May '24

Dear Folks, I am in the process of learning Sieve, and want to be able to keep an email in Inbox, while also keeping *one* copy in another folder. However, the same mail is copied from Inbox multiple times when I run sieve-filter -Wev .dovecot.sieve Inbox My attempt to prevent this fails: ... } elsif header :comparator "i;octet" :contains "From" "paypal(a)paypal.com.au" { if not duplicate { fileinto "paypal"; } keep; } Please can anyone enlighten me?

Namespace configuration for archive in different storage
by drinaldi＠trustitalia.it 06 May '24

06 May '24

Hello, i made this namespace configuration inside "10-mail.conf": namespace Archives { type = private disabled = no hidden = no list = yes ignore_on_failure = no inbox = no location = maildir:/mnt/archive-mail-storage/%n/Maildir prefix = "Archive." subscriptions = yes separator = . I need to set up the storage for archive on a different storage than the inbox is located. Thunderbird, now seems that can see the subfolders inside the archive that start with dot but cannot access the "cur" folder where inbox mail are stored. Can you help me?

Is there any solution for this?

doveadm backup empties the remote host? SERIOUSLY???
by Nils 29 Apr '24

29 Apr '24

Sure it's my own fault - no discussion about that, but seriously? How dangerously unintuitive it that? I found it when I was searching for a good practice to migrate a mail server with rsync and I mistakably assumed it works in the same direction as rsync. Luckily i have a backup from all mails except today's. Please, someone tell me what's the best procedure to migrate dovecot.

doveadm backup has problems with some accounts
by roger.meier＠4synergy.com 29 Apr '24

I try to setup for our mailserver (in a dc) a job backup to a secondary server (in our office) with "doveadm backup" via the -R option. (rsync , rsnapshot and so on tooks too long at the moment) For the most user accounts all work as expected, but for three users it always fails First run: /usr/bin/doveadm -Dv backup -Ru user1 tcp:mua01.domain.intra:12345 > Dec 01 08:54:21 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Debug: Mailbox INBOX: Mailbox opened because: copy caching decisions > Dec 01 08:54:22 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Warning: Deleting mailbox 'Archiv.Allgemein unsortiert': UID=1 GUID=1350559209.P2052Q54.lin-mail1.intra is missing locally > Dec 01 08:54:22 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Debug: brain M: Import Archiv.Allgemein unsortiert: Import change type=save GUID=1350559209.P2052Q54.mail1.intra UID=1 > hdr_hash= result=Reverting local change by deleting mailbox - No more local mails found > Dec 01 08:54:22 doveadm(70126): Debug: brain M: Import Archiv.Allgemein unsortiert: Saved UIDs: > Dec 01 08:54:22 doveadm(70126): Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=661,uid=0): Disconnected: Connection closed (fd=9) So it aborts on the lines above and a incomplete maildir is on the local server. so the next doveadm try say's that he can't delete INBOX , etc. > Dec 01 09:03:33 doveadm(user1)<70169><TzH+MmKhaWUZEgEAy5X8iQ>: Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. This a very old account on our server which was migrated over different iterations of our dovecot mailserver. The user behind the account uses outlook over years. Is the space here a problem?

On the filesystem the folder has the name ".Entw&APw-rfe" and also other users has similar folders in their mailboxes.

Dovecot Server issue, cache corruption

Hello, I'm using Thunderbird 102 to atempt to retrieve my messages via imap (have tried both 143 and 993) first I wasn't getting any error messages now I am. This is with Dovecot 2.3 on Debian 12.5.

Is it possible to setup ntlm authentication then proxy it to the mail server ?
by karl.l＠as7600.net 26 Apr '24

26 Apr '24

Hi, This is my dovecot version: ``` root@freebsdsvr:~ # dovecot --version 2.3.21 (47349e2482) ``` I'm having trouble in making dovecot as proxy to the mail server when using ntlm authentication. My setup looks like this: email client ------> dovecot (will act as proxy) -------> mail server so basically the email client will connect to dovecot but dovecot will forward it to the mail server. Proxying using auth_mechanism as PLAIN is working but if I use ntlm authentication it just connects into the dovecot server and dovecot server does not proxy to to the mail server. I tried using passdb driver = sql, passdb driver = static, passdb driver = lua and all of them are working when the email client connects using plain auth, once dovecot authenticates the user it will proxy it to the mail server but when I use ntlm authentication it just connects to dovecot and does not do a proxy to the mail server. I switched on all the debugs and I found out in the log that when I connect using PLAIN auth it calls the passdb and gets my default_fields or my proxy fields ```proxy=y``` and ```host=mailserver_domain``` which causes dovecot to proxy into the host(my mail server). but when I connect using NTLM auth it calls the passdb but it does not return my default fields for proxying (when it uses the sql passdb driver it just connects to the database and does not run the password_query) and I think it uses the output from the ```ntlm_auth``` of samba that dovecot uses because it retunrs the field user=username and original_user=username@domain This is the example logs that I recieved once I connect using ntlm and it does not proxy it to my mail server ``` Apr 18 03:37:29 freebsdsvr dovecot[12084]: auth: Debug: mysql(192.168.254.131): Connecting Apr 18 03:37:29 freebsdsvr dovecot[12084]: auth: Debug: auth client connected (pid=12268) Apr 18 03:37:29 freebsdsvr dovecot[12084]: auth: Debug: auth client connected (pid=12270) Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client in: AUTH 1 NTLM service=imap session=Js8TT04WcMnAqP5/ lip=192.168.254.131 rip=192.168.254.127 lport=143 rport=51568 Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client passdb out: CONT 1 Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client in: CONT 1 TlRMTVNTUAABAAAAB4IIAAAAAAAAAAAAAAAAAAAAAAA= (previous base64 data may contain sensitive data) Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client passdb out: CONT 1 TlRMTVNTUAACAAAAFAAUADgAAAAFgooC57WwKq2q4U8sdAAAAAAAAAAFwAXABMAAAABgEAAAasdasdasdAAAA9FAFMAQwAuAE4ARQBUAC4AQQBVAAIAFABFAFMAQwAuAE4ARQBUACad4AQdsQBVAAEasAFABFAFMAQwAuAE4AdaRQBUAC4AQQBVAAQAAAADABQAZQBzAGMALgBuAGUAdAAuAGEAdQAHAAgA/h8T7O2Q2gEAAAAA Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client in: CONT 1 TlRMTVNTUAADAAAAGAAYAFwAAACIAIgAdAAAAAAAAeABAAAAABgAGAEAAAAAWABYARgAAAAAAAAAAAAAABYIIAHMAcwAzAFcATwBSAEsAUwBUAEEAVABJAE8ATgBXKrBA2vF7fMicRiasLK/IyI3fbM46rQ7JHcti/0TU02AqasdasdasdhceI+BaeqMjrAQEAAAAAAACAL88ampDaARzhirKymxxcAAAAAAIAFABFAFMAQwAuAE4ARQBUAC4AQQBVAAEAFABFAFMAQwAuAE4ARQBUAC4AQQBVAAQAAAADABQAZQBzAGMALgBuAGUAdAAuAGEAdQAHAAgA/h8T7O2Q2gEAAAAA (previous base64 data may contain sensitive data) Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: auth(userName,192.168.254.127,<Js8TT04WcMnAqP5/>): Auth request finished Apr 18 03:37:30 freebsdsvr dovecot[12084]: auth: Debug: client passdb out: OK 1 user=userName original_user=userName@FREEBSD-TEST ``` Here's the logs that I get when I connect via Plain Auth and it does the proxy to my mail server ``` Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: mysql(192.168.254.131): Connecting Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: conn unix:auth-worker (uid=0): Server accepted connection (fd=15) Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: conn unix:auth-worker (uid=0): Sending version handshake Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: conn unix:auth-worker (uid=0): auth-worker<1>: Handling PASSV request Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: conn unix:auth-worker (uid=0): auth-worker<1>: sql(ss3,192.168.254.127,<zwTdK04W9MbAqP5/>): Performing passdb lookup Apr 18 03:27:39 freebsdsvr dovecot[12084]: auth-worker(12138): Debug: conn unix:auth-worker (uid=0): auth-worker<1>: sql(ss3,192.168.254.127,<zwTdK04W9MbAqP5/>): query: SELECT destuser, password, host, 'Y' as proxy FROM proxy WHERE user = 'userName';

using keycloak
by A. Schulze 25 Apr '24

25 Apr '24

Hello, I'm relative new to oauth2. I like to understand a setup for dovecot but https://doc.dovecot.org/configuration_manual/authentication/oauth2/ is not enough for me. Could anybody describe a simple setup where dovecot uses keycloak. For simplification I would start with keycloak's builtin user management only. - how to configure dovecot - how to configure keycloak - how to test with 'curl --verbose --some-magic-options imap://dovecot-server' Thanks, Andreas

Which DKIM application for postfix 3.9.0
by dovecot＠outputservices.com 25 Apr '24

25 Apr '24

I am upgrading to postfix 3.9.0. I have not used DKIM in previous postfix installs, but I would like to start now with the new google rules. I have done some research and opendkim is the most recommended, however, other research states the opendkim has been abandoned by it's maintainers. So I am looking for a good alternative dkim software that will work with postfix that I can compile myself. I do not run on any linux version, so therefore I can not just apt-get a new dkim application. I run Solaris and therefore need to compile my applications, postfix and dkim. Any good suggestions will be appreciated.
