Upon further testing, it seems that the issue below may only be a display bug in doveconf. In other words, the remote filter appears to work as configured, even though it is displayed with duplicate prefix length by doveconf.

Is this sufficient information to report a bug or is there some other protocol?

Dovecot --version: 2.2.9

I configured the following in local.conf:

remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes }

But, when I run doveconf -n, I see:

remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no }

Note the repeated network prefix length (/27/27 and /24/24).
