it's wonderful how this free (as in libre) system so many people have created 
has been turned into walled gardens to make money for someone else.

well it's resulting in earthlink rejecting e-mails from pilot. It not like we're 
going to convince earthlink to use someone else.

Is there a solution to this for TriLUG or do I have to start using gmail?

So far I have 3 people I can't send to from trilug

o 554 208.79.82.66 has a poor reputation on Cloudmark Sender Intelligence 
(CSI) http://csi.cloudmark.com/reset-request/?ip=208.79.82.66

o 550 IP 208.79.82.66 is blocked by EarthLink. Go to earthlink.net/block for 
details.

o 550 csi.mimecast.org Poor Reputation Sender. - https://community.mimecast.com/docs/DOC-1369#550

It's a bit of a maze of mirrors at the moment. I don't know if the information 
to block us is coming from one place or if these three systems have decided 
independantly to block us.

thanks

Joe
