wow! it only took me 13 hours, but I figured it out:


virtual_aliases_local_and_com:
   driver = redirect
   condition = ${if and {\
                           {exists{/home/${lookup{$domain}lsearch* 
{/etc/userdomains}{$value}}/etc/$domain/shadow}}\
                           {\
                               !or {\
                                     {\
                                               match\
                                                   {\
                                                     ${\


lookup{$local_part}lsearch{/home/${lookup{$domain}lsearch* 
{/etc/userdomains}{$value}}/etc/$domain/shadow}\
                                                       }\
                                                   }\
                                                   {\N.*\d.*\N}\
                                     }\
                                     {\
                                               match\
                                                   {$local_part}\
                                                   {\N.*com$\N}\
                                     }\
                                 }\
                           }\
                     }\
               }
   allow_fail
   data = :fail: $local_part email address at this $domain was not found
   verify_only
