configured solr - question 1
by Wojciech Puchar 11 Dec '19

11 Dec '19

tested dovecot with solr. Works well. But it uses TCP connection between solr server and dovecot. Can it be password protected? I have other things than IMAP on the same server including remote users. i don't want them to be able to do mess.

Solr for Dovecot on Debian 9, package has correct binary?
by John Gateley 11 Dec '19

Hello, I am trying to get Solr full text searching working on Debian 9 with Dovecot, and I suspect the binary for dovecot does not have solr enabled (--with-solr). root@elephant:/etc/dovecot/conf.d# /usr/sbin/dovecot --build-options Build options: ioloop=epoll notify=inotify ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw fail SQL driver plugins: mysql postgresql sqlite Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap(plugin) nss passwd prefetch passwd-file sql root@elephant:/etc/dovecot/conf.d# If I want to use solr, do I have to build dovecot myself? I'd prefer to use the debian package (Debian 9 for now). Thanks! John

Learning ham/spam with IMAPSieve: sa-learn-ham.sh terminated abnormally, signal 11

Hello, I am trying to get rspam to learn what is spam and what is ham. After following the IMAPSieve guide in the dovecot wiki (https://wiki2.dovecot.org/HowTo/AntispamWithSieve) the mail.log shows the following, whenever I move a mail from the Spam folder to my inbox and vice versa: sieve: Opening script 1 of 1 from `/usr/lib/dovecot/sieve/report-ham.sieve' sieve: Loading script /usr/lib/dovecot/sieve/report-ham.sieve sieve: Script binary /usr/lib/dovecot/sieve/report-ham.svbin successfully loaded sieve: binary save: not saving binary /usr/lib/dovecot/sieve/report-ham.svbin, because it is already stored sieve: Executing script from `/usr/lib/dovecot/sieve/report-ham.svbin' sieve: action pipe: running program: sa-learn-ham.sh Mailbox INBOX: Opened mail UID=2996 because: mail stream Debug: waiting for program `/usr/lib/dovecot/sieve/sa-learn-ham.sh' to finish after 0 msecs Error: program `/usr/lib/dovecot/sieve/sa-learn-ham.sh' terminated abnormally, signal 11 Error: sieve: pipe action: failed to pipe message to program `sa-learn-ham.sh': refer to server log for more information.

What we could provide now would be the XML-Response from Solr. The corresponding search query sometimes causes this error. But Solr's answer seems to always remain the same - in my opinion this already indicates a bug of Dovecot? The XML response can be downloaded here: https://owncloud.eideo.de/index.php/s/8oyJaf5HBK6zdbr Kind regards, Fabian

I can confirming using commands 'openssl s_client -connect <keycloak_server>:443' or 'curl -v https://<keycloak_server/' all returns normal and no errors. Altering some of the SSL options in dovecot such as 'ssl_ca = </etc/pki/CA/certs/root_ca.pem' or 'ssl_client_ca_file = </etc/pki/CA/certs/root_ca.pem' does not help either.
