We have a new one.
I've been working with Bluehost support on this and they're stumped.
Around 20 e-mails go out and then the thing stops.
They're seeing no error messages on their side. There are none of those Network Solution mis-cues that something bad is happening to the server.
The tech thinks it's a PHP issue be he wouldn't know where to start. Have you seen this before?
I'm currently press the stop button and restarting every 20 or so out going messages. This is going to be my day long job.
