Problemer med email.

Hej,

Efter jeg har opgraderet min outlook til en nyrer version (2007), er den begyndt at sende halvdelen af sendte mails tilbage. Jeg får denne meddelelse efter ca. 5 dage:

This is the mail system at host cicero-fbr1.cybercity.dk.

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can delete your own text from the attached returned message.

                  The mail system

<"blabla"@hotmail.com>: delivery temporarily suspended: connect to
    mx2.hotmail.com[65.54.245.40]: Operation timed out



Andre som kender dette problem? Det er primært hotmail udbydere som ikke kan modtage mine mails.

Hvorfor?
