Plusnet on block list

[#1]

Hi trying to send a email from  Aol email account to a old established hotmail account and I get -
"Unfortunately, messages from 64.12.237.  weren't sent. Please contact your Internet service provider since part of their network
is on our block list."
Is this normal plusnet behavior? its fine using the same accounts at work.
Thanks

It could be that your IP address that you're using at the moment has been listed?
If you go to http://whatismyip.com does the IP address match up with the one in the rejection?

A quick check shows that you aren't sending via the Plusnet servers but the AOL servers so you had better have a go at them

HMMM interesting the returned mail messages always referred to my "internet provider" (plusnet) so them i always blamed. I cannot see AOL been very motivated in fixing my free email account So i guess i will have to set another up elsewhere.

You don't need to use the AOL server for sending - change it to relay.plus.net
