DOTS. (Depends On The Situation).
We have the "luxury" of not having to cater to WinWoes or Apple 'native'
alleged-MUA's, and use different SSL arrival ports for:
- faster setup than STARTTLS
- helping 'ban' MUA's we don't want to support anyway
- selecting different acl routing rules for different user groups
Admittedly non-standard, I will agree, but derned handy... ;-)
