Lmtp redirection to other backend server
by Marc Roos 11 Dec '19

11 Dec '19

I have currently a working local delivery working ok on 2 backend servers. The backend servers use slapd/nslcd/nscd for local accounts. If I enable proxy=yes in the lmtp config section, I am getting this error 'auth: Debug: passdb out: FAIL#0111#011reason=Configured passdbs don't support credentials lookups' which is obvious because I do not have a passdb. I am not sure if it is possible to get this value from the system environment eg. nslcd/nscd, without the need to configure some separate ldap lookup in dovecot? Or do I really need to configure a ldap lmtp lookup just for this host attribute? What would be an efficient solution?

Can a mail admin ban atomia.com from posting? I mean, I like the idea that every post is clogging up their support queue, but really, not that much. Sent from my iPhone

configured solr - question 1
by Wojciech Puchar 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

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
