Hi all,
I've been setting up a fresh postfix server, and I've really appreciated
how great the docs are. In the spirit of making them even better, I'd
like to share a comment/suggestion.
If I correctly understand the messy history of port 465 vs 587, for
submission port 587 with StartTLS was preferred, but now port 465 with
implicit TLS is preferred (because it eliminates the possibility of
downgrade attacks). And port 465 is now named `submissions` instead of
`smtps`.
I suggest therefore that the string `submissions` should appear
somewhere in:
http://www.postfix.org/TLS_README.html
Similarly, though the string `465` appears, it's only in the context of
the older obsolete `smtps` sense, for MTA to MTA communication.
Cheers,
Sean
