For example. My domain is www.myuniquedomain.com.
I see people sending email as me and Im getting the returned mail. Is there any way to stop this. I dont have relaying enabled. Basically using sendmail, one can send email as anyone. So i can setup an email server and send an email out as firstname.lastname@example.org
2nd question. Is there any code to disallow attachments to certain users. For example I have a user called email@example.com
. He should never be getting an attachment whether it contain a virus or not. Is there a way to deny the email if there is an attachment?
I have done ample research on both of these topics. Just cannot find a solid solution.
Thanks in advance.
