[Dovecot] Requiring STARTTLS only on some networks

Hello Timo,

is there a way, either in 1.2.x or in 2.x to activate

disable_plaintext_auth=yes

only for some address or network ?

The idea would be to enable clients from the internal networks to keep making clear text connections while forbidding it to the rest of the world.

Thanks.
