Nice service you got, IMHO a good idea is to support a non-url-click email addresses, smthng like myname.nc@..., where ".nc" means "I will handle the urls by myself"

WELL DONE!

Perhaps using sub-addressing and the '+' or '-' character like GMail or qmail.

I was going to say the same thing. Alias accounts would be awesome... blah+mymail@mailops.com blah2+mymail@mailops.com etc.. would all point to mymail@mailops.com This would be really useful if you could implement that.

edit: Also, having the mails (subject and body) display as a xml feed would be ++, some of these temp email sites offer this, but only show the subject and a link to the message which isn't part of the feed.

Actually the way existing mail servers work foo+bar@domain.com and foo+bar2@domain.com get delivered to foo@domain.com (if the server was configured for "+ addressing")
