We have a requirement to implement email2case process in which we are adding to-address from Email Message object to Case object field.
For example if email@example.com send an email to our email(email2case) address then email message process builder will update to address value in case object email. This is working fine.
Now the problem is we need to have case auto response rule on the same field which we got from email message object to case object but that is not matching the criteria.
Is there some solution for this to achieve it? I already tried apex trigger but no success yet.
