Sunnie, maybe just like happened to me, i can now all of the sudden use my account without any activation message. Just try to login at
http://webmail.eq-sys.com/horde/index.php . Use the full e-mailadress as login (including
@msgplus.net. Or use it as a POP3 box in your own e-mail client using
mail.eq-sys.com as both SMTP (outgoing) and POP3 (incoming) server.
