Whenevr I try to send an email (using horde webmail) to a domain that is not hosted on my server, I get:
"There was an error sending your message: Failed to add recipient: [email protected] [SMTP: Invalid response code received from server (code: 553, response: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1))]"
I do have SMTP Authentication set in Mail, and I understand how to authenticate with an email client, but this using Horde webmail, shouldn't horde be able to authenticate on my server? Please help.
