That's not a correct statement - your email does reach google as can be seen
from your qmail log

That is a good question - I "guess" that google's email system thinks you're
sending them spam. If you want your mail to be accepted you may need to have
implemented SPF and domainkeys. Also I think that if you are using a script
to generate the email then ensure that you are creating the required headers
and that your mail conforms to the rfc.

You can also try to send mail to your google address by hand i.e. telnet to
google's mail platform on port 25 and mimic the smtp conversation by hand to
see if you can get any further....

HTH
