Hello,
For a specific use case,I need to rewrite emails intended for certain users (but not for the entire domain) to another mailbox hosted on another domain.
Example: john.doe@initial.com to john.doe@new.com
I need to do this for several users (but not all users) and would like to know if there are any 1-to-1 regexps or Cisco ESA built-in features or filters that would help. Or do I need to use a content filter for each recipient (lots of content filter to write :))
Except rewriting the rcpt-to is it mandatory to rewrite as well the "to" header?
Thank you
