When I try to access my mail account on the fgd.exofire.net:2095 address, I don't get any problem and can see my inbox and everything else.
But, when I click on the "New Message" button and try to send an e-mail to a yahoo mail account, it tells me that "There was an error sending your message: Failed to send data [SMTP: Invalid response code received from server (code: 503, response: All RCPT commands were rejected with this error: Temporary local problem - please try later Valid RCPT command must precede DATA)]".
According to previous posts on the forum, I've understood that the problem was due to an inconstency in the file that tells the server which mail SMTP accounts are available.
I hope this little explanation will help you to solve my problem,
Thanks a lot
