Microsoft’s broken mail services

Today I was trying to send email to a person at and the email was bounced back. The reason? Fox uses Frontbridge, a service Microsoft provides that hosts and manages Exchange servers for email.

As part of this service, they have a black list (RBL) called 88.blacklist.zap created by Terry Zink ( which simply does not work. Judging by the number of complaints about this list I’m surprised they even use it.

I haven’t sent email to anyone at Fox in several months, our severs do not handle massive amounts of email and there is no reason we would be listed on this or any other RBL. In fact, this is the first time that I have come across an RBL that blacklisted our SMTP server.

In the header of the message they include a reference to send email to, yet how many non-technical users even notice this little bit of information in the bounced email?

Worse, it took several tries before I finally received a reply from Microsoft.

But what really takes the cake is that sending a reply to the message Microsoft sent me results in the same stupid list blocking the reply!
