Authentication Problem with dovecot-2.3.0.1
by Odhiambo Washington 08 Mar '18

08 Mar '18

I am a little confused here. I have been running 2.2.34 which I installed in /opt/dovecot2.2 I installed 2.3.0.1 to /opt/dovecot23 I then used config files from /opt/dovecot2.2/etc/dovecot to /opt/dovecot2.3/etc/dovecot and all I did was sed -i.BAK 's/dovecot2.2/dovecot2.3/g'. Dovecot started and was running file. Next, I manually crafted config files for 2.3.0.1 based on the example config files provided which diff-ing those with what I had for 2.2.34. I doub't if I missed something crucial during the process. 1. I realized that I cannot start 2.3.0.1 when I enable submission, since my Exim MTA is already using that port. This persists even if I tell the submission protocol to use a different port than 587. I tested 2587, but it would appear that 587 is hard-coded! 2. I realize that "unix_listener auth-client" service ceased to exist! 3. *I realized that while 2.2.34 runs with default_pass_scheme = MD5-CRYPT, 2.3.0.1 would not run with it.* 4. I have run dovecot -n from my 2.2.x installation and 2.3.x installation and here is the diff from the two files. I am confused why authentication is failing with dovecot-2.3.0.1 when it uses 2.3.x config files using MD5-CRYPT scheme while it is succeeding with dovecot-2.2.34 using the same. *Mar 07 22:30:22 auth: Info: sql(user.name(a)domain.name <user.name(a)domain.name>,192.168.55.97,<4CETl9dmscvAqDdh>): Requested DIGEST-MD5 scheme, but we have only MD5-CRYPT* Maybe the problem is elsewhere??? I need a 3rd eye to help me.

Hello, I've got dovecot going with postfix and MySQL database for user and domain storage. Dovecot handles the authentication. My last login is not working, does anyone have a table example and configs? I looked at the wiki page on the lastlogin plugin but obviously what I'm doing isn't working, I keep getting message write was unsuccessful for the lastlogin ip. I'd appreciate any help. Thanks.

Authentification fails in dovecot 2.3.0.1
by post＠volker-wysk.de 07 Mar '18

Hi I've upgraded dovecot from 2.2.22 to 2.3.0.1. Now I can't authenticate any longer. My mail client says that the user name and password are rejected by dovecot. I get this line in /var/log/auth.log: Mar 6 19:28:02 desktop auth: PAM audit_log_acct_message() failed: Operation not permitted And this in /var/log/dovecot.log: Mar 06 19:28:02 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 06 19:28:02 auth: Debug: auth client connected (pid=5615) Mar 06 19:28:02 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=ggZPmsJmIoh/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=993 rport=34850 local_ Mar 06 19:28:02 auth-worker(5617): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/lib20_auth_var_expand_crypt.so Mar 06 19:28:02 auth-worker(5617): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): lookup service=dovecot Mar 06 19:28:02 auth-worker(5617): Debug: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): #1/1 style=1 msg=Password: Mar 06 19:28:02 auth-worker(5617): Info: pam(v,127.0.0.1,<ggZPmsJmIoh/AAAB>): pam_authenticate() failed: System error Mar 06 19:28:04 auth: Debug: client passdb out: FAIL 1 user=v Mar 06 19:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts in 4 secs): user=<v>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<ggZPmsJmIoh/AAAB> Now it seems I can't go back to 2.2.22 as well: https://wiki2.dovecot.org/Upgrading/2.3 says "Downgrading is possible to v2.2.27 and later.

AppArmor profile for Dovecot on Debian Stretch
by André Rodier 07 Mar '18

07 Mar '18

Hello all, Is there any guide to help in the configuration of Dovecot for AppArmor on Debian / Ubuntu ? Or maybe does any of you already have something that works? I am actually adding AppArmor on an email server project, and I had some trouble with the versions from Debian. I would like to avoid - if possible - the long try and error process for each Dovecot executable. I am using IMAP, LMTP, Sieve and ManageSieve, with LDAP users. The full project reference is here: https://github.com/progmaticltd/homebox ii dovecot-core 1:2.2.27-3+deb9u2 amd64 ii dovecot-imapd 1:2.2.27-3+deb9u2 amd64 ii dovecot-ldap 1:2.2.27-3+deb9u2 amd64 ii dovecot-lmtpd 1:2.2.27-3+deb9u2 amd64 ii dovecot-managesieved 1:2.2.27-3+deb9u2 amd64 ii dovecot-pop3d 1:2.2.27-3+deb9u2 amd64 ii dovecot-sieve 1:2.2.27-3+deb9u2 amd64 Thanks for your advices André

Mail addresses with quotes + Postfix
by Philipp Berger 07 Mar '18

07 Mar '18

Dear all, I have a working setup with Postfix + Dovecot, storing users in a MySQL table. I ran into problems setting up and using a mail address like a"@"b(a)mydomain.tld, which by RFC should be valid, but leads to problems in Dovecot. From my debugging, I can see that on the lookup, Dovecot replaces %n with "a" (quotes added by me) and %d with "b(a)mydomain.tld" (quotes added by me). So the original quotes are gone, and the domain/user split is incorrect. I am not sure of Postfix passes the address without quotes to Dovecot or whether Dovecot can not handle quotes correctly, but I was hoping that someone with more insight into Dovecot could help me out here. System Info: Debian 9, Postifx 3.1.6-0+deb9u1, Dovecot 2.2.27-3+deb9u1 Postfix master.cf for Dovecot: dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/lib/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} I am grateful for any hints :) Thank you in advance, kind regards, Philipp

extra IMAP folders: how to make all clients use the same Sent folder?
by Stanislaw Findeisen 07 Mar '18

07 Mar '18

Dear All I have just setup IMAP with Maildir, but unfortunately some clients create their own folders instead of using those specified in 15-mailboxes.conf . What could be the reason? Here's what it looks like: > B list "" * > * LIST (\HasNoChildren \Sent) "." "Sent Messages" > * LIST (\HasNoChildren) "." Gesendet > * LIST (\HasNoChildren) "." Entw&APw-rfe > * LIST (\HasNoChildren \Trash) "." Trash > * LIST (\HasNoChildren) "." Papierkorb > * LIST (\HasNoChildren \Drafts) "." Drafts > * LIST (\HasNoChildren \Sent) "." Sent > * LIST (\HasNoChildren) "." Ausgang > * LIST (\HasNoChildren \Junk) "." Junk > * LIST (\HasNoChildren) "." INBOX > B OK List completed. Here for example "Gesendet" (meaning "Sent" in German) is a folder created by some Android client app. This app uses it to store its sent mail, while another client uses the Sent folder. Also, is it correct that all those folders (both pre-made and extra) get created directly in the user's maildir, alongside cur, new, tmp and Dovecot index files? Shouldn't there be any subdir? > # dovecot --version > 2.2.13 Thanks! Stanisław

Hello! Dovecot 2.2.34 (874deae) Pigeonhole version 0.4.22 (22940fb7) After the update to pigeonhole version 0.4.22 the following configuration does not work.
