Hi Andreas,
From my side it looks like bluewin mailserver is not accepting any email at the moment.
We had some funky problems with our loadbalancers this morning.
(delivery temporarily suspended: connect to mx49.bluewin.ch[195.186.18.99]: Connection timed out)
hehe.. mx49 is just a tarpit server ;-)
telnet 0 25 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. 220 mx49.bluewin.ch not so ready
Regards, Adrian
