Hi everyone,
I'm having a problem with sending mail after installing 5.6 and performing a 'restoring from desktop '. This is the error message: An unknown error has occurred. Subject 'testmail', Account: 'mail', Server: 'murdock', Protocol: SMTP, Server Response: '451 Temporary qmail-queue failure.', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC6A.
On the previous version of SME, CLAMAV was installed but even after installing it on 5.6 the error remains the same. Can anyone plese help me???
Greets, Arno
