Hi folks,

i have a very specific problem, and need some help.
I could not find a solution to block or reject a specific combination of a sender and receiption domain.
Our configuration, 4 linux server which using a mail host as smart relay.

Currently, one of the gobal mail players limited us and i have to internally reject a specific combination.
Here a example:

mails from noreply@somedomain.com AND receiption domain domain1.com, domain2.com, domain3.com has to be rejected without notice. All other mails has to be sent

Otherwise mails from xyz@somedomain.com AND receiption domain domain1.com, domain2.com, domain3.com should be sent out.
Same mails from noreply@somedomain AND receiption domain domainXYZ.com should be sent
Thanks for your help

you may need to define trusted domains.. i dont remember the whole thing right now but google would have answers, try searching for allowing trusted domains.
