I am using Imail Server 9.21
I have multiple domain hosted
My email address is email1@domain.com
when i send email to email@yahoo.com then ask email authentication (Email Authentication working successfully)
When i send email to same domain from email1@domain.com to email2@domain.com then email authentication not working
Thanks
Wrong question you are asking him, he needs to concentrate on getting authentication settings correct.
"Life is a succession of lessons which must be lived to be understood." Ralph Waldo Emerson (1802-1882)
Your email client should be configured to send all outgoing email via authenticated.
