Hi Jim,

A "550" response is usually because the remailer's spam filter (or more specifically, the service the remailer contracts with to provide that filtering function) thinks your email is coming from a source known to be a provider of spam. My experience with these filters is that they are incredibly crude, often rejecting all email from a particular provider, legitimate or otherwise. Yes, they block spam, but there's a lot of non-spam that gets swept up with it too. Not their concern, apparently, as they did block the spam...

Often these lists get corrected without (additional) intervention, either because of the outcry from others, or an alert staff. If not, you will need to contact your provider and let them know that you are being blocked. They will need the email header information, where the specific spam filter contact information is usually located. I've not had much luck getting things cleared up with the filtering service on my own.

Good luck,

Greg KOO6TH
