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 (18.104.22.168) but I can't see this (now) being associated with madasafish.com:
$ dig madasafish.com
madasafish.com. 20317 IN A 22.214.171.124
madasafish.com. 20317 IN A 126.96.36.199
The IP now appears to match something else:
$ host 188.8.131.52
184.108.40.206.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.
