Say I have an account that I can login to as
foo@bar.com, but can receive email to
foo@bar.com and
foobar@bar.com, I'd like to be able to send email using the aliases that are enabled for my account (administrator settable of course, I can see plenty of admins NOT wanting this). Does that help a little? I'm thinking something along the lines of a "From:" drop down with the default being the login (or account) name (btw, I discovered I could log in to the webmail account via aliases too!) allowing the user to select his alternate email aliases as the sender. In my personal case, I'd like to subscribe to mailing lists using an address of account-mailinglist@domain and reply using that so my actual _personal_ email account isn't posted all over the 'net. But I can see this being useful outside of my personal case though, else I wouldn't be asking for it.
