Thank you for clarifying it, I wasn't aware that amavsid-new can do
that. However, at http://www.amavis.org/#faq-mta I read:

The Postfix Before-Queue Content Filter setup, also known as
smtpd_proxy setup, is not a supported or recommended setup with
amavisd-new, which is not a transparent SMTP proxy by design. See
caveats in README_FILES/SMTPD_PROXY_README

Unfortunately, I couldn't find the referenced README in the sources.
Can you tell us more in this regard?

Thanks,
