Why not use the smtp *submission* port (and leave 25 disabled)? Also, SMTP auth is a good thing. Much better than the old cowboy
days of just trusting some networks..Well, one intention for mail via IMAP is that most people keep a
copy in their Sent folder, which is located remotely as well - in
contrast to POP3. So, you have only one transmission of the (same)
contents.
There are already some other SMTP/IMAP extensions created for that
purpose by Lemonade IETF group, which I think is a better way to do
this.
There is another one: Some mail clients have a really bad SMTP
AUTH / TLS implementation, in opposite to IMAP.
And how many such clients support sending mail via IMAP? :)
I guess it would already work with most clients if you specifically
save the message to a specific mailbox, instead of just clicking the
normal send-button. But I doubt anyone would actually want to use
that way.
