At the risk of resurrecting a somewhat old thread, is this still expected to work? I am looking at the same warning, and it has the same IP address as reported above (188.8.131.52) but I can't see this (now) being associated with madasafish.com:
$ dig madasafish.com
madasafish.com. 20317 IN A 184.108.40.206
madasafish.com. 20317 IN A 220.127.116.11
The IP now appears to match something else:
$ host 18.104.22.168
22.214.171.124.in-addr.arpa domain name pointer avasout04.plus.net.
So do you think I should include madasafish.com, avasout04.plus.net (or maybe even lots of avasout*.plus.net? I stopped counting how many there were at 6 ...)
My inclination is to use that 04 one, but my email I guess might come out of more than one point depending upon PN's routing.
