Doveadm protocol; dovecot v2.2.10
by David White 30 Jul '18

30 Jul '18

Hi there, Just wondering what is considered current best practice for managing dovecot? The options I see are: Doveadm binary Doveadm protocol via socket Doveadm http protocol I’m currently on v2.2.10 and it appears the doveadm protocol command set is limited to just the “mailbox” commands and the http protocol hasn’t been implemented. Is the doveadm http protocol still experimental in v2.3.2?

Seems like a minor cosmetic bug with [ dovecot -n ] ssl_alt_key = </etc/pki/private/some.key.pem ssl_key = # hidden, use -P to show it

Restricting SSL/TLS protocol versions on Dovecot 2.2.22
by J Doe 30 Jul '18

30 Jul '18

Hello, I have a question regarding SSL/TLS settings for Dovecot version 2.2.22. In: 10-ssl.conf there are two parameters: ssl_protocols ssl_cipher_list ssl_protocols is commented with “SSL protocol to use” and ssl_cipher_list is commented with “SSL ciphers to use”. If I want to disable SSLv3, for example, do I need to use both parameters or will disabling SSLv3 ciphers in ssl_cipher_list do the same thing ? So is: ssl_cipher_list = !SSLv3 …equivalent to: ssl_protocols = !SSLv3 ssl_cipher_list = !SSLv3 Thanks, - J

[Dovecot] quota-status not working in distributed environment
by Benoit Panizzon 30 Jul '18

30 Jul '18

Hello List Quick overview of our set-up: Postfix / Dovecot (2.2.2.1) / MySQL Cluster on (at the moment) three Servers to create a HA environment where you could easily add additional servers as the demand or load grows. Circular dovecot replication is used so each server uses another one as replication partner and allowing one server to fail. Dovecot Proxy Feature being used, so we can use round-robin DNS and each server can forward the connecting user to the correct 'master' for his mailbox. So far, everything works as expected. Now we want to reject emails to 'full' mailboxes during SMTP to prevent backscatter and use the quota-status policy service from within postfix. That works fine, if the mailbox or it's replica is present on the machine where quota-status is called, but it fails if it's run on a machine where neither the mailbox or the replica is present. In our case, we get a correct SMTP 550 'Mailbox Full' Reject in two cases and a LMTP generated bounce in the later case. Also `doveadm quota get -u user(a)example.com` return the correct quota if run on the two machines which have the mailbox and it's copy locale, but return 0% used if run on the other machine. Is there a way to get quota-status to also use the proxy feature to request the quota information from the correct machine? Or is the postfix policy daemon call to the quota-status socket documented somewhere (it must be, but where?) so we could implement it from within the Milter? (we use the sendmail Milter API from postfix to filter spam and viruses, do sender/recipient rewriting, forward bounce matching, rate limmiting, login/IP statistics to block botnets abusing phished addresses and legal intercept stuff anyway) Kind regards Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

[SOLR] Where is solr-schema.xml?
by Peter Nabbefeld 27 Jul '18

27 Jul '18

Hello, running dovecot 2.3.2.1 on Arch Linux, and installed solr 7.4.0. According to the wiki, there should be doc/solr-schema.xml, but I cannot find it. Tried "whereis dovecot": dovecot: /usr/bin/dovecot /usr/lib/dovecot /etc/dovecot /usr/include/dovecot /usr/share/dovecot /usr/share/man/man1/dovecot.1.gz But I cannot find any xml files using find /usr/{lib,share}/dovecot -name "*.xml" Kind regards Peter

Imap post-login script

Dovecot v.2.2.32 and I have configured two imap post-login scripts and it seems like after successfully login scripts are not closed (dovecot_node/imap imap-postlogin : multiple processes are running still) and after some times there are too many processes and the limit is reached (imap proces_limit 1500): 1) #!/bin/sh case $IP in 10.10.1[1-2][0-7].*) exec "$@" ;; 10.11.2.4[0-9]) exec "$@" ;; esac CHECK_USER=`PGPASSWORD="password" /usr/local/pg952/bin/psql -h 10.11.1.3 -q -t -U postfixuser -d mail -c "select imap_allowed from users where name = '$USER' LIMIT 1"` if [ $CHECK_USER == "t" ] ; then exec "$@" fi if [ $CHECK_USER == "f" ] ; then exit 0 fi 2) PGPASSWORD="password" /usr/local/pg952/bin/psql -U postfixuser -d mail2 -h 10.11.1.3 -c "select last_auth('$USER','$RIP2','1')" > /dev/null exec "$@" Regards, Jack
