Your virtual(5) alias table rewrote the recipient address. You had
addres mappings disable in the first two passes through the queue,
but the final pass applied virtual aliases.
Presumably you have something equivalent to:
u...@domain1.com u...@domain2.com
in your virtual alias table. Don't do that. Users in virtual mailbox
domains don't need virtual(5) rewrites. Only virtual alias domains
need recipients to be rewritten into a "real" domain.
