Hello,
I use MailEnable Professional in our building, but there is a problem like this

After Providing SMTP Authendication with the system@posta.com Account
It has been observed that e-mail can be sent to test2@mail.com by using the address test1@mail.com,

I Analyzed The Situation By Disabling The "Delivery Using Mail Address" Option On A Different Platform,

But How Can I Do This Operation On MailEnable?
I expect information from you, good work ...
