Email relay question
I can receive email in and send email via an email account hosted on the server but cannot send email out via an application on my server. The message is
reject: RCPT from Mynewserver.com [xxx.xxx.xxx.xxx]: 454 4.7.1 <
I want to be able to send emails out from applications running on my server. What typically causes the relay to not happen. Is it on my server or the receiving server?
Thanks in advance for the help.
