Hi. This is the qmail-send program at tib.gov.tr.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<uyari@tib.gov.tr>:
Sorry, no mailbox here by that name. (#5.1.1)

--- Enclosed are the original headers of the message.
