localhost provides no benefit, how much is the gain from turning it
off? On the Dovecot side it's simpler because Dovecot considers
loopback secure (and it probably offers more actual benefit because
IMAP connections are persistent.)
Anyway, if you do choose to pursue this, there are many options. I
think the easiest would be to make a separate smtpd instance with
overrides as needed:
[ master.cf ]
127.0.0.1:10587 inet n - n - smtpd
[ with other overrides from your submission service ]
Then configure Roundcube to connect to 127.0.0.1:10587 for sending.
