I have had a postfix mail server running for some time mostly just taking mail for a couple of personal domains for me. I was recently asked if I could email services for a family member, and I'm having a bit of trouble setting everything up.
If I send a test email to dave@domaintwo.tld, it gets rewritten as david@domainone.tld. The dave->david conversion is done in the virtual map. However the domain name changes, too.
This changed second domain then gets caught in my catchall for domainone, resulting in the email going to the wrong place.
I'm sure this is something simple to do with how I've set up the virtual domains, but I think I've tried every possible combination, and can't get it to work correctly!
Any help greatly appreciated.
The error:

@domainfour.tld aaron

What I think happens:
- Email comes in to dave@domaintwo.tld from an external server
- virtual map matches dave@domaintwo.tld (I want server to delivery to mailbox for used david.)
- Server redirects to david@domainone.tld (domainone.tld is the server's domain)
- david@domainone.tld is then matched by @domainone.tld and delivered to user george.
This happens to any address other than george@domainone.tld.
Server details:
- postfix: mail_version = 3.1.15
- procmail: procmail v3.23pre
