Hi,

For my application I send mails when an idea is submitted. The mails goes in most cases. Sometimes I get 2 errors

"Mailbox unavailable. The server response was: 5.7.1 Unable to relay for -"
"Unable to send to all recipients."

So I am not able to ensure that mail goes all the time correctly. The settings are all ok coz the mail goes sometime and fails sometime.... Could anyone help me out in this issue?
