The new server seems to be running great.  However, because NotifyWire changed its IP address, some ISPs (ATT, Comcast, AOL, SBC) are blocking emails from NotifyWire.com  I've been working to get the SPF record right for the domain and working with these ISP to confirm NotifyWire's mail server is on the up and up, but it may take some time.

If you are with one of these providers and your email alerts are important to you, you might want to consider adding another email account from gmail or yahoo to your NotifyWire.com account and adding it to your searches.  I don't believe this will be a long term problem, but I'm not sure how long it will take with some ISPs.

Update: I haven't been getting as many bounce back emails lately.  I think that means the SPF record is right and has replicated across the Internet.

Update 2: AOL seems to be the only ISP still blocking NotifyWire alerts.
