Comment 41 for bug 327773

I suggest that MSN be added to the summary, as it uses the HTTPMail protocol also.

MSN and Hotmail use different servers, but the same protocol. The 'incoming
server' in account settings would need to have the correct one depending on the
service.

Re: protocol that MSN Explorer uses:
I think MSN Explorer *does* use HTTPMail; HTTPMail support is only beta for
Outlook Express. Per the MSN Announcement email:
   "MSN Hotmail provides account access **to Outlook Express customers** as a
    beta service." (emphasis mine)

Re: IMAP-like functionality:
According to the OE Help, HTTPMail works like IMAP, except that you don't need
to subscribe to particular folders; they're all shown.

When you synchronize folders (make available for offline access), you can choose
to get (for each folder):
1) All Messages
2) All New Messages
3) Headers Only
4) Nothing

Re: POP3-like behavior and/or sent items being local automatically:
I do not suggest any POP3-like access; keep it similar to how OE does things.
If your Sent Items on the Hotmail/MSN servers starts getting too full, drag and
drop the messages to the local Sent Items folder. I may want some of my Sent
Itmes to be accessable through the web interface...
