Does anyone know what this means?

SORBS is a database of IP addresses known or suspected of sending SPAM.
It would seem that your ISP has managed to get listed as a SPAM sender. If another ISP (the one you friend is with) uses to SORBS database to black/whitelist email addresses then mail from your ISP will be blocked.

The problem with these sorts of lists/databases is that you can easily get on them due to some minor issue but it takes a lot longer to get off them. Of course it could be that your ISP is not in the SORBS list and that your friends ISP has been compromised.
CHeck the SORBS site listed and you can check IP addresses to see if you're blocked.

Thanks Geoff, I tried to send an email this morning and it went through O.K., go figure

I'm with Optusnet and I receive frequent emails from a N. American ISP, Comcast. Unfortunately, Optusnet have been on Comcast's blacklist for five or six years and nothing I, or seemingly, Optus can do will change that. The result is that I can't reply to those comcast.net emails.

Thats ok, optus do exactly the same thing to other domains. They dont even know which ones and can't edit their blocked list. So if you really need to receive emails, I wouldnt use the optus servers. Even getting them to admit that it is their server software that is the problem is hard work.
