Hi Diarmaid - Yes, I do have (and just confirmed it via the link below). We are discovering now, that it might be (ready?) a problem with Craig's List. The same user just tried to send via their Yahoo account and it bounced back too.

Please setup matching DNS and rDNS records: http://bind8nt.meiway.com/itsaDNSmess.cfm >>>>>>>>>>>>>>>> The only thing that I changed on our end in the last week, was moving our domain name to a new DNS host (we outsource it). I ran a DNS Report a few hours ago, and it didn't show any errors. The user is sending from a domain that is hosted virtually on our server. Any thoughts, or am I just missing the obvious? Thanks!
