Got email from vmobile.us today. It's listed on [WS] and [JP].
I checked the evidence and it's kind of flakey. The mail in question was mailing by wirelessdealernetwork.com.
WDN has 2 NANAS sightings to it, both dated 2004-09-19 and posted by the same guy. Registered on 2004-06-08, NS blacklisted, listed on SURBL [WS], [OB], [JP].
Whether the recipient opted-in or not is not quite clear, but he's telecom-related. It may be spam, it may be not.
In any case, vmobile.us was registered on 2004-05-12 and blacklisted by me on 2004-09-14. I shouldn't have blacklisted at that age without further evidence / checks. The NS is not blacklisted, no Google hits for spam other than my own listing. Oops! The domain of the owning company, usa-telecom.net, is two years old.
So I think [WS] should probably also unlist vmobile.us, as I will do.
My lesson: Just because the mailing list may be spammy and the TLD notorious doesn't mean a domain mentioned deserves listing on SURBL.
