Be specific, what type of domain is "mydomain":
* Local domain listed in $mydestination?
* Relay domain listed in $relay_domains?
* Virtual mailbox domain listed in $virtual_mailbox_domains?
* Virtual alias domain listed in $virtual_alias_domains?
* Other, please explain.
Please be very clear whether you're trying to reject mail *to*
non-existent recipients, or *from* non-existent senders. I am
assuming "recipients" for now based on the above.

What database?

The recipient domain is "ankara.edu.tr"...

Your connection is authenticated, so mail to "remote" domains will
be permitted. (Remote means not any of "local", "relay", "virtual alias"
or "virtual mailbox").

Message bounced to postmaster.

As configured.

This is not recommended.

This is wrong for an Internet connected machine unless all outbound
email is via a "relayhost".

Perhaps too short.

The domain "ankara.edu.tr" is not any of the above.

Very few users set these parameters, you probably shouldn't either.

So you may get away without "dns lookups", but there's no need to
disable DNS explicitly, that's just a source of potential future errors.

No point, empty does the same thing cheaper/faster.

Any domains listed there? Does the non-existent recipient lookup
key yield some return value in this table with "postmap -q"?
