Limit IMAP/IMAPS listening IPs

Hello list.

I am running dovecot v2.2.13 on debian 8.8;

I tried to add a "address =" statement for only localhost and one
private IP, but then I got a complaint from system:

dovecot[20515]: Error: systemd listens on port 143, but it's not configured
in Dovecot. Closing.

What is the proper way to resolve this?

TIA & Regards,

Dudi

I suggest to use iptables for this.

$ mkdir -p /etc/systemd/system/dovecot.socket.d
$ vim /etc/systemd/system/dovecot.socket.d/ports.conf

content:

[Socket]
# unset all ports defined in the global file
ListenStream# add our new ports
ListenStream=[1.2.3.4]:143

$ systemctl daemon-reload
$ systemctl restart dovecot.socket dovecot.service

of course the [] are only needed for ipv6 IPs and not also IPv4

Thanks for the prompt reply!

How do I specify more than 1 IP? I'd like 127.0.0.1 and say 192.168.1.100
only.

Regards,

Dudi

This is why sane admins don't use the *EVIL* systemd

Thankfully there are still some modern distros that refuse to touch it.

Name sounds cute, the idea sounded OK, but the reality is, its a
_REDACTED_ useless pile of REDACTED REDACTED REDACTED

Full text search indexing behavior and testing?

Hi,

I'm confused about FTS. https://wiki.dovecot.org/Tools/Doveadm/Index
say's:

"Messages can also be added automatically to full text search index using:

plugin {
  ...
  fts_autoindex = yes
}"


So I added "fts_autoindex = yes" into dovecot.conf (I'm using
single
config file). That's it? How to test FTS? Or I still must use some
external indexing server?

Hi Mart,

I think it?s a bit more? you might want to refer to
https://wiki.dovecot.org/Plugins/FTS
<https://wiki.dovecot.org/Plugins/FTS>

You only mentioned the function to automatically start indexing. Nothing about
were this should actually happen. We are using Solr?

mail_plugins = $mail_plugins fts fts_solr

and:
plugin {
  fts = solr
  fts_solr = url=http://solr.example.org:8983/solr/
}

The autoindex does nothing more than automatically sending incoming mails to the
FTS index system. Solr is external while Lucene is library based and saved
inside the mailbox hierarchy. There even is an implementation for Elasticsearch.

For all options? you might want to observe the logs once it has been enabled.

   Hi! It's harmless event leak. This is a known issue to us.
