mail.app: email send and receive doesnt work anymore

[MacPeach]

I installed and updated all mobileme setups and now, my smtp server list shows "disconneced" for every email address... No email in - no out!
Even on the webmail, I dont get any emails anymore from my friends... since 36 hours. Anybody else having such a problem?

What a mess. I'm having all kind of problems as a .Mac prat -- smtp disconnected and the lot!

Same, I can't send an email to a friend and I'm not getting any new ones.
