Fix my exim communication problem?
I have an old program from years ago. It's trying to deliver mail to a new cPanel server with the latest exim. But the sending always fails with the following. Is there anything I can change that allows this to work? Is the problem the client because its improperly using AUTH LOGIN without seeing the advertisement? Or is it my server because AUTH login is not enabled?

Hey there! The issue would be the script sending that AUTH and then not authenticating properly.
In general, with any type of mailing script, it's best to authenticate using a full email address and password to a local account.

I just whitelisted the sending server so AUTH is not needed now. thanks.
