BTW, please do not use real domain names as examples. We have
example.com and example in all gTLDs as well as many other TLDs,
which has been set aside for examples. Or better yet, when seeking
help on mail routing issues, use the real names!
Wildcard forwarding is a very bad idea. You WILL be abused by
spammers into becoming a backscatter source.

Same-envelope forwarding to external sites is also quite likely to
become a source of problems for you. When you receive and forward
spam to this address, gmail content filtering will identify it as
such, and will regard you as the spammer.

Did you note in the documentation that virtual_maps was deprecated
with Postfix 2.0?

I do not know what you read. You can indeed use virtual_alias_maps
with any and all address classes. See:
http://www.postfix.org/ADDRESS_CLASS_README.html
http://www.postfix.org/postconf.5.html#virtual_alias_maps
http://www.postfix.org/VIRTUAL_README.html (might also help)

Good. Sounds right to me. No catchall in relay_recipient_maps means
that my backscatter warning above is moot in your case.

virtual_alias_maps = hash:/path/to/your/virtual_alias_maps
/path/to/your/virtual_alias_maps contains:
f...@bar.com foo...@gmail.com
Note the problem as mentioned above, but otherwise, it works.
