Relay access denied , user unknown in virtual alias table

When I send from a local mailserver with following virtual.table (i use
mysql) I get the mails for asperl@i-cons.at and xy@i-cons.at correct.

@i-cons.at office@i-cons.at

asperl@i-cons.at asperl@i-cons.at

with virtual table

i-cons.at anything

@i-cons.at office@i-cons.at

asperl@i-cons.at asperl@i-cons.at



I get mails to asperl@i-cons.at coorect, mails to xy@i-cons.at produces
followibg error:

Jul 27 13:21:59 ireds postfix/error[11303]: 7B8F9193B7:
to=<office@i-cons.at>, orig_to=<xy@i-cons.at>, relay=none, delay=0,
status=bounced (user unknown in virtual alias table)

When I sen from a mailserver out of my local network I get for both
mailadresses an with virtual table version 1 following error:

Jul 27 13:27:13 ireds postfix/smtpd[11329]: 5908B193B7: reject: RCPT from

helo=<mcwebi.han-solo.net>



with virtual table version 2 this:

Jul 27 13:29:58 ireds postfix/error[11346]: DD886193B7:

virtual alias table)
