I suspect you'll need to do session logging e.g. protocol pop3 { ... rawlog_dir = /writable/logdir/%u } then mkdir /writable/logdir/user chmod 0777 /writable/logdir/user to obtain session transcripts of what server/client are doing. I don't see any obvious errors from the logs that indicate any failure. I do see the INBOX is rather large so maybe a timeout is involved. Joseph Tam <jtam.home(a)gmail.com>

Multidomain ssl config ?
by Maurizio Caloro 16 Oct '22

16 Oct '22

on postfix now this seems to run, and with dovecot i need also handle this two domains, but appairing this error messages. like: Jun 29 20:49:28 Dovecot/imap-login: Info: Disconnected (no auth attempts in 0 secs): user=<>, rip=a.b.c.d, lip=37.120.190.188, TLS handshaking: SSL_accept() failed: error:14094416:SSL routines: ssl3_read_bytes:sslv3 alert certificate unknown: SSL alert number 46, session=<FdklDjkdfrkfi> Running with Debian Buster # dovecot --version 2.3.4.1 (f79e8e7e4) # nmail.caloro.ch local_name nmail.caloro.ch { ssl_cert = </etc/letsencrypt/live/nmail.caloro.ch/privkey.pem ssl_key = </etc/letsencrypt/live/nmail.caloro.ch/fullchain.pem } # nmail.calm-ness.ch local_name nmail.calm-ness.ch { ssl_cert = </etc/letsencrypt/live/nmail.calm-ness.ch/privkey.pem ssl_key = </etc/letsencrypt/live/nmail.calm-ness.ch/fullchain.pem } thanks for possible help

Re: LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

Again, a bit more reading got me to adding this to my passdb config: username_filter = *(a)domain-a.com This way, I can control which domains get to authenticate via my ldap backend, which gives me time to design a good way of saving other attributes there. If anyone have other ways of doing this, ie., having multiple domains on ldap/freeipa and getting an elegant integration with Dovecot, I’d be glad to hear.

I actually saw that it was possible, and it works, but I came across another problem and I wonder if you have any tips about it: On my current dovecot setup, I use SQL as the backend. So I have the following users: francis(a)domain-a.com <mailto:francis@domaina.com> francis(a)domain-b.com <mailto:francis@domain-b.com> Those are separate users which their own mailboxes. However, I have a freeipa that is configured for the `domain-a.com <http://domain-a.com/>` realm. However, since I am using `%n` for the uid search: auth_bind_userdn = uid=%n,cn=users,cn=accounts,dc=domain-a,dc=com And pass_filter = (&(objectClass=posixAccount)(uid=%n)) It of course leads up to both users above being able to authenticate with the same password. Is there a way to limit ldap authentication to just one domain, or perform a search where both username and domain are checked? I could use the `mail``attribute to filter users, but I imagine that if two users have the same mail configured, I’d run into trouble….

LDAP just for passdb
by Francis Augusto Medeiros-Logeay 14 Oct '22

14 Oct '22

Hi, I couldn't find it in the documentation, so I was wondering - is it possible to configure Dovecot to use LDAP for passdb and keep using SQL for userdb? I would like to do that before I come up with a good strategy to expand my ldap schema to support other mail attributes for virtual domains, aliases, etc. I am currently using FreeIPA. Best, Francis

"make check" fail at test_program_refused
by A. Schulze 14 Oct '22

14 Oct '22

Hello, I moved my buildsystem to an other platform (I do not fully control) and now receive this error on "make check" Error: program tcp:127.0.0.2:42027: connect(::1) failed: Connection refused test_program_refused ................................................. : FAILED The build run on jenkins buildnodex spawn up on a kubernetes cluster. What I noticed so far: the buildnode opereate ipv4 only but has an entry in /etc/hosts: 127.0.0.1 c4a84c76f0d6 ::1 c4a84c76f0d6 Maybe that's the glitch ... I tried dovecot-2.3.15 and 2.3.19.1. Both fail (only the portnumber differ) Is there an option to disable only one specific test? I dislike to skip "make check" at all. Andreas

what are the options to 'interact' with a dovecot imap user
by Marc 14 Oct '22

14 Oct '22

I am looking for a user friendly way to have a user to tell the 'server' to either store or remove an email address. a. My first thought was to use imapsieve for this and have an imap sieve plugin store/remove the email address of the message that is being dragged into a predefined monitored folder. This would work with any imap client b. I was thinking about the message Flagged[1]. I am curious how would I be able to detect this (in sieve)? This does not seem to be stored in the source of the message. Although every client seems to support it, it would probably conflict with every day use cases. c. Then you have these colours and/or categories. But these do not seem to propagate across clients. Where are these even stored? Any ideas on how this can be done?

Director hashing
by Dan Conway 14 Oct '22

14 Oct '22

Hello all, I have a 2 node director setup that uses checkpassword for authentication as well as backend assignment through director tags. director_servers = 192.168.1.10 192.168.1.20 director_mail_servers = 192.168.2.10@srv1 192.168.2.11@srv2 checkpassword writes the following to Dovecot on successful authentication: proxy=y\tdirector_tag=<tag>\tport=<port>ssl=yes\tdestuser=<email>\t This seems to work just fine. However, when I attempt to view a users current hash/initial config: # doveadm director status "user(a)domain.com" Current: n/a (expires -1) Hashed: Initial config: I get null data. There does appear to be a hash mapping of some sort however: # doveadm director map -u user(a)domain.com 1140334690 # doveadm director map -h 1140334690 user(a)domain.com The use of doveadm director move has no effect. doveadm reports it moved the user, but it does not: # doveadm -v director move "user(a)domain.com" 192.168.2.11 Info: User hash 1140334690 moved to 192.168.2.11 When using checkpassword and supplying fields to Dovecot, should I also be including another field to populate hashes for director? I could be missing something obvious in the docs. I'm on version 2.3.18 (9dd8408c18). I have not included dovecot.conf due to the size. If someone needs to see it I can supply it.

keep in mind that the cert purchased is only for the name : mail.paulkudla.net thus i fail to see why it is throwing error 42, however this seems to be a patch to thunderbird as well i did not have to change the servers base ssl stuff (*.scom.ca) so that is still working or will that need to be updated as well eventually postfix is perfectly fine ????? Note from sni.conf (ssl config file) - aka *.scom.ca is ok ?? : ssl = yes verbose_ssl = yes ssl_dh =</usr/local/etc/dovecot/dh-4096.pem ssl_prefer_server_ciphers = yes #ssl_min_protocol = TLSv1.2 #Default *.scom.ca ssl_key =</usr/local/etc/dovecot/scom.pem ssl_cert =</usr/local/etc/dovecot/scom.pem ssl_ca =</usr/local/etc/dovecot/scom.pem -- Happy Tuesday !!!

One-off backup
by Ian Evans 11 Oct '22

11 Oct '22

I run a small email server for me and the missus. Six dovecot users. Our host is migrating our server instance. They usually (99.9999% lol) go off without a hitch. As we don't have dovecot running elsewhere, I'm assuming doveadm is the wrong tool. If we want to make a one-off backup prior to the migration, is shutting down postfix and running tar czf mailstorage.tgz /path/to/mail okay? Thanks.
