[Dovecot] Dovecot.conf

[Clovis Tristão]

Hi,

I am mounting a server of email with the Dovecot as MUA,  i would like
to restrict the access to imap and ipop to one determined range of IP.
As I configure this in dovecot.conf, I did not understand the
functioning of listen = * or [: ]
Thanks a lot,
Clovis
