Hi, someone knows what this error means?

"javax.mail.MessagingException: Can't send command to SMTP host;  
nested exception is:  
java.net.SocketException: Connection or outbound has closed"

This is when I do a test to send an email.

The mail configuration is ok, and I did the Alarm Notification module's restart.

Why do you think the configuration is OK when you are failing the Send Email Test?

It was working a few weeks ago, but it stopped sending mails. Then, I did a new email configuration and ran a couple of tests, it was working, but again, it has stopped.

It sounds as though the configuration is _not_ OK or you have intermittent IT problems.

You're going to have to provide a lot more information.

Thanks for your advice. Yes, it is an intermitent problem on the email server.  
I've done a test with another mail server and it is working again.

Thanks a lot.
