Use canonical_maps to rewrite all instances of the address
(header, envelope, sender, recipient).
Use virtual_alias_maps (not virtual_aias_domains) to rewrite
the envelope recipient only.
In both maps,
@alaska.com @alaskan.com
would do the domain translation.
Caution: with this, Postfix will accept email for any addr...@alaska.com
including addresses that are later found to be undeliverable. If
someone starts to send lots of mail to random addresses at alaska.com,
then your mail queue will fill up with bounce messages.
