emails from @pbfa.org are returned to the sender with a message sending they were timed out. I spoke to a plusnet tech person last week who said it was firewall/filters at the senders end. Their tech people say exactly the opposite - it is a filter at the plusnet end. They woud like plusnet to check their server IP but I can't get through to plusnet on the phone. Any suggestions for a non-tech person stuck in the middle?
