Hi
I am having problems with sending/receiving mail since an upgrade to SME-server 7.2
No mails can be sent, and no mails is received

(I have changed my real domainname to mydomain.dk for the public domain and mydomain.net for my local domainname)
If I try to send a mail with Thunderbird I get an error: The message could not be sent, because connection to SMTP-server mail.mydomain.net failed. With webmail the error is: unable to connect to smtp server localhost:25
I use Fetchmail to fetch mail from a mailhotel. The maillog says:
