Unresponsive email address

[AnthonyB]

I have a contact with an 'aol' email address. He is able to and does receive emails that I send to him from my btinternet address but is unable to reply or to initiate a post to me which I can receive. I have checked blocking settings etc.  My other contacts all seem to be able to function normally.

When you checked your "Blocked Senders" in the settings did you check that the AOL domain was not there?

Have you tried adding your friends email address to your "Safe Senders" list?
