I'm using
java to send mail from a website ("contact us" forms, order updates, etc.). It worked fine for several months on our development servers, but we began having problems when we moved to a hosting service.
The mail is sent properly for a while...hours or sometimes days. Then we start throwing the following:
(no, I'm not using the e-mail address "user@host.com", I just took out the real address to protect the client)
When I restart Jrun, the mail works again...for a while. Then it stops working again until I do another restart.
The hosting service swears up and down that we don't need any authentication or anything like that. They claim there's nothing strange going on with their mail server. Why would it work temporarily and then stop until the next jrun restart? We're all stumped.
Thanks,
Mike
