Topic: Mail list problem external listAllowedUser not work for local SMTP
I have a mail list ALL@DOMAIN.COM which is sent to all and it's set to moderator. I added another virtual domain email USER@DOMAINB.COM into the listAllowedUser. If USER@DOMAINB.com using the same server to send email to ALL@DOMAIN.COM, it will reject the connection immediately. But if sending via external SMTP, it works as expected.
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ALL@DOMAIN. Subject 'test', Account: DOMAIN', Server: DOMAIN, Protocol: SMTP, Server Response: '450 4.1.2 <ALL@DOMAIN>: Recipient address rejected: Domain not found', Port: 25, Secure(SSL): No, Server Error: 450, Error Number: 0x800CCC79
