[BlueOnyx:27029] postfix & pop-before-smtp

[Tomohiro Hosaka]

Hello.

I am preparing to upgrade from 5209R to 5210R.

While working on the admin panel, I found that postfix cannot be
combined with poprelayd.

HACK(popauth) in sendmail.mc does not log the operation even if
confLOG_LEVEL is raised, so it is difficult to know how much
POP-before-SMTP is used.

I considered sendmail for compatibility, but postfix SNI support is
also attractive.

In my environment, I found that POP-before-SMTP works with postfix by
making the changes below.
