How to receive e-mails in a silverlight application?

I'm wondering whether anyone can help me with how to set up mailboxes for my silverlight application users.

Sending e-mails was simple enough, but now it seems to get tricky.

How do I implement an IMAP or POP3 service? I've followed a couple 开发者_如何学Goof questions here on SO, but the answer is still eluding me...

Can anyone maybe send me a in general direction? Any useful answers would be very much appreciated.

You can use the MailSystem.Net (LGPL). It provides full support for SMTP, POP3, IMAP4, NNTP, MIME, S/MIME, OpenPGP, DNS, vCard, vCalendar, Anti-Spam (Bayesian , RBL, DomainKeys), Queueing, Mail Merge and WhoIs.

Never tried this but heard of it one time: http://www.emailyak.com/
