Bug#933679: qpsmtpd: No Received header if received_hook configured

["Peter J. Holzer" <hjp-debian@hjp.at>]

Package: qpsmtpd
Version: 0.94-4
Severity: normal

Dear Maintainer,

the qpsmtpd included in Debian Buster doesn't handle the received hook
correctly. Instead of prepending the line to the headers it is returned
to the caller (which means that no Received header is added at all).

I will send a patch shortly.

(I think this was also present in Debian Stretch, and I will check
upstream next.)
