Sorry about the last mail, my spam filter declared my outgoing mail as spam as well.
This is what my mailserver detected when it analyzed your mail:
8.5 URIBL_SBL Contains an URL's NS IP listed in the Spamhaus SBL blocklist [URIs: m ail.f ink.o rg]
Maybe Swisscom/Bluewin does kind of the same, just call it differently?
Note I added some whitespaces into the domain.
