If you Google phx.gbl, you'll find a similar question at the top of the search results but the answer requires subscribing to a paid service. In my own case, the domain turned up in an email to a listserv from someone with an msn.com email address. The individual had aroused the suspicion of someone on the list and I surmised that the phx.gbl was part of the cause and so tried to chase it down. I tried tracert and whois to no avail and, like the person who posed the similar question on the paid service, I also noticed lots of newslist posts with the domain in the Ggoogle search results.
What is the phx.gbl domain and is there any reason to be particularly suspicious of it?
Thanks & best -- Jim
