Plesk Mail and WHMCS issue.
I have just installed Plesk on a server I have.
All is working within Plesk.
I setup a test user and created an email account.
Everything looks like it is working until you send an email.
I get this error - Server error: '554 5.7.1 ***@gmail.com: Relay access denied'
I also have an issue with WHMCS, it connects fine from what I can see but when it goes to create a service it times out and gives me this error:
Module Command Error
CURL Error: 7 - couldn't connect to host
I am running the latest WHMCS and Plesk 11
