It seems obvious to filter out the spam. To be honest, I thing Google is
doing the right thing here, because you are a source of spam.
I'm not blaming Google.

But, on the other hand, is it really 'spam' we're sending, or just messages which are spammy? It's a subtle difference, but the recipient 'wants' to receive the messages (for some definition of 'want') because they are deliberately sending them to themselves. Is it spam if I send *myself* messages about viagra?

It depends on your definition of 'spam'.

You should
take appropriate measures. Maybe you have to accept a few false
positives. You could also modify your spam filter so that positives are
sent back to the sender, with a warning.


I think filtering them, and marking them (not blocking) and sending them onto 
Google may be the best answer.

Please note that this mailing list is not intended to help with setting
up mail servers. The (design of) the SMTP protocol is the main topic here.

Yes, sorry. I am a regular member of this list, and it just came up as the most likely place to ask. I am suitably ashamed.

(Maybe there SHOULD be an SMTP feature to indicate MTA forwarding is taking place, because it certainly doesn't seem as if we're the only people who will have this problem - domain hosts often do general email forwarding, often without any spam filtering)
