iCloud SMTP server timeout

Hi all

Using iCloud through Mail on OSX 10.7.4, I cannot send any emails

I receive them just fine, but it will always timeout when trying to send emails

The smtp server I seem to be on is p02-smtp.mail.me.com. I tried to ping it and it has 100% packet loss, although this might just mean they reject ICMP requests.

Sending from my iPhone or iCloud on the web works just fine

Any ideas?
