thanks - that did the trick :-)
I was also able to whitelist whole domains using the parentheses/matching
technique.
Here's my final config, in case its useful for Randy or others:
/etc/postfix/virtual :
# 1. whitelisted individuals:
r...@hotmail.com r...@hotmail.com
# 2. whitelisted domains
/(.*)@foobar.com$/ ${1}@foobar.com
/etc/postfix/virtual.pcre :
/./ mails...@example.com
virtual_alias_maps = hash:/etc/postfix/virtual pcre:/etc/postfix/virtual.pcre
>Rather than an access map, you can use virtual_alias_maps as
>discussed in the parallel thread "Many to one address rewriting,
>exceptions exist."
