[lug] MTA poor reputation issue

[Chip Atkinson]

Hi everyone,

Recently I moved a server to a cloud provider to reduce electricity usage 
and noise at home.  I still have my comcast static IP and could keep that 
if necessary.  I'd like to move most everything to the cloud but at a 
minimum want to turn off the server.

My latest problem is that when I try to email some people 
from it, I get errors like this:

(host as-av.iinet.net.au[203.0.178.180] refused to talk to me: 
554-icp-osb-irony-in8.iinet.net.au 554 Your access to this mail system 
from 167.88.120.115 has been rejected due to the sending MTA's poor 
reputation. If y
ou believe that this failure is in error, please contact the intended 
recipient via alternate means.)

If I telnet to port 25, I'm just disconnected with that message, so it's 
not a configuration issue.

Anyone have any suggestions around this?

thanks in advance.

Chip
