Hi,

The 'address' setting in the “Service configuration” of the Configuration Manual 1 says:

Space separated list of IP addresses / host names to listen on. […] Defaults to listen setting.

I'm finding this part confusing as it seems that by “listen setting” it is referring to the 'listen' setting in the “Dovecot Core Manual” 2 which is described as:

A comma-separated list of IP addresses or […]

which leads me to suspect that either “listen setting” refers to something else (what?) or there's some inconsistency with the documentation or perhaps a bug/foot-gun here.

Regards,
