I have an email alias staff@??? that contains all the staff member
email addresses of the company. However, only the company bosses
eric@??? and john@??? are allowed to send email to
staff@???.
I've setup a message filter in system wide filter (system_filter.exim) like
this:
## staff@??? restriction:
if $h_to:,$h_Cc: matches "staff@???" and ($h_from does not match
"eric|john@???") then
fail text "You are not allowed to send mail to this address"
endif
It works fine for rejecting normal staff members from sending messages to
staff@??? using TO or CC. However if a normal staff sends email to
staff@??? using BCC, my filter failed to work.
Is there a way to stop people sending to staff@??? using BCC?
