initial replication or clone?
by Joachim Lindenberg 20 Feb '22

20 Feb '22

Hello, I want to improve availability of my dovecot installation by implementing replication as outlined in https://wiki.dovecot.org/Replication. I am wondering whether I have to install an empty copy or whether it is also an option to clone the entire existing system and then configure replication, just to avoid the initial overhead. Any input? Thanks, Joachim

Hello, With Dovecot 2.3.18 on AlmaLinux 8 I’m trying this: LIBEXTTEXTCAT_LIBS="-L/usr/lib64 -lexttextcat" ./configure --with-textcat … which gives me: checking for special_textcat_Init in -lexttextcat... no checking for special_textcat_Init in -ltextcat... no configure: error: Can't build with textcat support: libtextcat or libexttextcat not found I do have: > ls -la /usr/lib64 | grep textcat lrwxrwxrwx 1 root root 26 Oct 12 2019 libexttextcat-2.0.so.0 -> libexttextcat-2.0.so.0.0.0 -rwxr-xr-x 1 root root 22128 Oct 12 2019 libexttextcat-2.0.so.0.0.0 Is there some way of knowing what command it’s actually running that makes it say “libtextcat or libexttextcat not found”? Thank you! cheers, -Felipe Gasper

Using dovecot-shared for an shared index not working
by Achim Gottinger 18 Feb '22

18 Feb '22

Hello I'm in the process to migrate our mail server from version 2.2.13 with maildirs to 2.3.13 with sdbox. On the old server if we wanted an common index for the seen flag on shared folders we created an file called dovecot-shared in the mail_location folder and the mailbox folders. This does not work on the new server for all shared mailboxes the seen flag is stored per user. The log file shows this if the seen flag is changed Feb 18 13:24:15 SERVER dovecot[18887]: imap(USER)<18978><51HhlUnYeOfAwAx3>: Debug: imapsieve: mailbox shared/info: FLAG event (changed flags: \Seen) The dovecot-acl file for the shared/info/INBOX folder has the s flag set. I hope i can get a few pointers here how to get the seen flag working for all users again. On the old server the location variable for the shared folders had the variable INDEX defined which can not be used with sdbox. location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u:INBOX=/home/vmail/%%u/mail/.INBOX Does that imply that sharing the seen flag can not be used with sdbox?

Dovecot with Microsoft Azure OAUTH2 ?

Does anyone have experience successfully setting up Dovecot OAUTH2 for authentication with Microsoft Azure? I'm not sure what to use as tokeninfo_url and introspection_url in the Dovecot configuration. I would appreciate any help and advice. -- Best regards, Max Kostikov

Too many wait in auth process
by ismael.tanguy＠univ-brest.fr 18 Feb '22

18 Feb '22

Hello, I'm currently benchmarking new hardware aimed to serve around 70k users For now, our IMAP server have 13k users. To run imaptest, I've spwan some bench clients. Each bench client can run imaptest with 1000 clients. More than 1000 clients will load CPU of this bench client imaptest command (command are chosen from usage stat on our other IMAP servers): imaptest host=xxxxx port=xxx userfile=userfile mbox=/root/dovecot-crlf pass=sxxxx seed=123 clients=1000 select=194 uidfetch=94 noop=70 status=82 append=49 fetch=276 list=12 store=19 expunge=22 msubs=4 search=4 logout=1 delete=81 no_pipelining With one bench client, everything runs smoothly. # ps aux | grep dovecot | awk '{print $11,$12,$13,$14,$15,$16,$17,$18}' | sort | uniq -c 1 anvil: [221 connections] (anvil) 1 auth: [13 wait, 0 passdb, 0 userdb] (auth) 1 dovecot/config 1 dovecot/imap 84 dovecot/imap-login 1 dovecot/log 20 dovecot/pop3-login 1 grep dovecot 1 stats: [1307 connections] (stats) When a second instance bench instance start imaptest, clients of first and second instance begin to stall : 1400 stalled for 20 secs in command: 1 LOGIN"fakeuser644@mailbench...." "password" And : # ps aux | grep dovecot | awk '{print $11,$12,$13,$14,$15,$16,$17,$18}' | sort | uniq -c 1 anvil: [221 connections] (anvil) 1 auth: [1227 wait, 0 passdb, 0 userdb] (auth) 1 dovecot/config 1 dovecot/imap 37 dovecot/imap-login 1 dovecot/log 20 dovecot/pop3-login 1 grep dovecot 1 stats: [680 connections] (stats) Every auth go in wait, number of connection decreases. Using mysql or a password file give same results. I have used different values for service_count with also no success. I think my use of imaptest could be false. My understanding of service auth is limited for now because I'm quite new to Dovecot (I have previously worked with Cyrus). Thank you for every hints. Ismaël Tanguy

mail-crypt and mbox format
by cincodemayo_67＠yahoo.com 17 Feb '22

17 Feb '22

Hi, My Dovecot server of many years has been set up to use mbox email folders. I want to implement mail-crypt and after banging my head against a wall for a few days trying to get mail-crypt to work I decided to try it against a test instance of my server that I reset to use Maildir format and mail-crypt worked instantly. Does mail-crypt work with mbox format mail folders, or am I wasting my time unless I switch over to Maildir? The documentation at https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ doesn't explicitly say Maildir is required. Thanks in advance, Doug
