I've read any referrences about email relay and doing some experiences with disabling TLS Auth and so on. But, there's no clue about my problems
I have a mail server on 118.97.xx.yy networks, and I want to use mail client outside that networks. But I have receive error message that inform me the email server deny mail relay.
I try to add one by one the IP Address', but the MTA Settings have limitation only 10240 chars limit And how to resolve this issue ? So I can send email from outside network and using mail client.
