I am the host and I own my own servers which are located at the Softlayer Data Center in Houston. I have hundreds of sites on line and I have lots of your forms working on many sites now and they are on the same server as this issue. This server is about 1 year old now an running Centos v6 64bit o/s, linux w/Plesk 11.5 I also have 24/7 live engineers monitoring my network operations. If this is a server issue I would think the other forms listed below would not work? My daily morning server report shows no issues.
Here are a few of your forms on the same server that work just fine for reference.
Everything was working just fine till the date of this post. For reasons unknown your software just stopped working properly. In this case I have my operations@ mail box as a cc. Nothing is coming in. Not in spam, not in the mail q
