Step 1:
Bluewin does a reverse DNS lookup on your IP (195.141.232.78), which returns the following:
# nslookup
195.141.232.78
;; Truncated, retrying in TCP mode. Server: www.multipop.ch. Address: 195.141.232.253#53
78.232.141.195.in-addr.arpa name = mailhost.aa795.ch. 78.232.141.195.in-addr.arpa name = mailhost.aerni.net.
plus another 20 hosts
This is a silly reverse setup. A reverse lookup should only return one hostname, not 20.
