Smtp Tweak Question
I checked the option in WHM tweak settings
"Prevent the user 'nobody' from sending out mail to remote addresses "
From what I understand, this will disable "nobody" to send emails using my smtp.
There is another option in the WHM tweak settings which says this:
Include a list of Pop before SMTP senders in the X-PopBeforeSMTP header when relaying mail. (exim 4.34-30+ required)
What does this mean?
What I really want is my smtp (exim) only allow the emails in my domains that I host -- are authenticated to send email using my smtp. No email sender can be from any domains that are not in my server. How Can I acheive that? ( I have one server that hosts 4 domains that I run -- I dont sell webspace or account)
Please someone help. I disabled nobody but did not turn on the SMTP TWEAK SETTINGS ON. What I understand is this causes the smtp to be used by anyone without being authorized to send emails using my smtp.
Please help.
