I have problems applying filters to emails forwarded from an external server (such as Gmail).
Let's say I have 2 "forward-only" emails set up in DreamHost:
firstname.lastname@example.org -> email@example.com
firstname.lastname@example.org -> email@example.com
I can successfully apply filters on these, so that any emails coming in through "firstname.lastname@example.org" will go to a folder named "A", and any emails through "email@example.com" will go to a folder named "B".
However, I have another "forward-only" email set up:
firstname.lastname@example.org -> email@example.com
Now, I don't directly receive emails to this address, but I've set it up to catch forwardings from Gmail. So, it's like this:
firstname.lastname@example.org -> email@example.com -> firstname.lastname@example.org
The problem is that I can't find a way to filter these emails, so that they will be moved to a folder "C".
I have tried setting up a "To" filter for both "email@example.com" and "firstname.lastname@example.org", but to no effect.
Could someone give me some tips on how to set this up?
