How to Block External Recipient to Specific user in Domain Pure Message in Linux

Hi,

sounds like you are looking for a per user mapping, e.g. predefined blacklisted-senders-per-user, rather than a per recipient/sender policy modification (which is at least what I read from your description and steps).

So, given your example you might put john@contoso.com to the blacklists of user@domain.com.au and user1@domain.com.au, either using the web interface or by looking into using e.g. pmx-list add and have a sender/recipient dependent outcome in some test as:

address :all :memberof "From" "blacklisted-senders-per-user"
envelope :memberof "From" "blacklisted-senders-per-user"

Those tests wrapped up in if anyof (address,envelope) then reject 'blacklisted' at a proper spot in your policy should do the trick.

Best regards

Hello Zeljko, 

Not sure to have understand well your request however please find below my understanding.

You want to block every message come who from john@contoso.com.au to the following recipients user@domain.com / user1@dmain.com

If it's what you want to do, the best things could be a rule as follwo: 

If envelope from or header from is john@contoso.com.au

if recipient is user@domain.com

pmx_mark (add value into the log)
reject the message
stop

if recipient is user1@domain.com

pmx_mark (add value into the log)
reject the message
stop

Of course you can create a custom list to add both email addresses, then the rule could be similar : 

If envelope from or header from is john@contoso.com.au

if recipient is member of MyCustomList
pmx_mark (add value into the log)
reject the message
stop

Best regards,
