Hello,
Frankly, I'd ask you to justify having to meet both conditions.
If they can use Webmail, why not let them use a "real" client?
That's what we do here at NCSU.
That said, since you say you can meet condition 1, You might
create a proxy user who does all logins from the Webmail service.
Users would/should still have to authenticate to Webmail. After they
do that the proxy user actually logs in to the IMAP server. This would
probably take some work writing code on the webmail side of things
though in order to make sure users don't do things to other users.
Unless of course a webmail client already supports doing this.
Regards,
Earl Shannon
