Jesper Dybdal:
You're right: I had somehow overlooked"timeout talking to proxy
127.0.0.1:10024", which undoubtedly is the problem.? Port 10024 is the
pre-queue amavisd-new.

Now I just need to figure out why amavis times out.

Perhaps amavisd-new is doing slow DNS lookups?

usually much more than that.  unpacking archives, AV scanning them, checking
BAYES database...

The Postfix-side time limit is covered by smtpd_proxy_timeout which
has a generous default of 100s. Increasing this may result in remote
SMTP client timeouts and duplicate deliveries as the client retries.

another option is to use amavisd-milter instead of SMTP proxy.
It also allows using other milters, while you can't use multiple proxies.
