Re: smtp authentication for sending to external domain only

With default iRedMail setting, it requires smtp authentication to send email to both external and internal domains.
So why bother? Why turn on authentication for external domains but turn off for internal domains? Why not just force smtp authentication? It's easier to maintain.

Re: smtp authentication for sending to external domain only

hi Zhang,

Thanks for reply. I need this because I am in process of migrating from other mail server to iredmail.
I set to forward email from other server to iredmail so I can migrate gradually, but the user from other mail server is not using authentication, so when he try to send email to internal domains that exist in iredmail, it will be reject, user not login.
If I add the external ip to mynetwork, then it will be hole, right ?
That's why I need to set like that for migrating, if migrating process finish, I set back to original setting again.
Any idea ?
