I mean virtual mailbox domain listed in $virtual_mailbox_domains.
We have a multiple domains setup which is consist of "ankara.edu.tr" and
its subdomains.
For example when I tried to send an email from an
existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.} to a
non-existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.} then it redirects the
mail to postmaster@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.}

We are using MySQL for mapping and authentication purposes.

It bounces even when I commented it out.

Yes it is. We have messaging gateways and our MX records point to them.

Yes. I've tried "ankara.edu.tr" for $mydomain then i got "unknown user"
for all emails from existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.} to
existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.}.

transport_maps contains our other mail server's address for different
domain that are not listed in $virtual_mailbox_domains:
ogrenci.ankara.edu.tr smtp:[ip-address]:25
"postmap -q existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.}
proxy:mysql:$config_directory/maps/sql-valiases.cf" yields some return
value and non-existent-address@{ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.} does not.

Yes. All of our domains (ankara.edu.tr,
agri.ankara.edu.tr,politics.ankara.edu.tr etc.) and "postmap -q
existent-domain proxy:mysql:$config_directory/maps/sql-vdomains.cf"
yields return value "virtual:" for the existent-domains and nothing for
the non-existent-domains.

No, it doesn't. Only for existent-addresses.
And thank you for other suggestions.
