Is it possible to create a single rule where the condition is:
No. but you can create two rules. One says “if mail contains XYZ in the senders address do THIS”. The other one says “if mail is from teh following people do THIS”
The result is the same.
Can a rule be created that checks outgoing mail and warns if a certain criteria have not been met? Example: mail addressed to joe.blow@address.com must be sent from group “networkops”.
