APPEND a regular expression map to your virtual_alias_maps
definition.
/etc/postfix/main.cf:
virtual_alias_maps =
...stuff you perhaps already have...
pcre:/etc/postfix/virtual_alias.pcre
/etc/postfix/virtual_alias.pcre:
# Send b...@whatever.example.com to b...@example.com.
/^bob@([^.]+\.)+example\.com$/ b...@example.com
