If you need correct per-recipient responses, the solution is
to use LMTP instead of SMTP to feed mail from Postfix to amavisd.
On the amavisd side there are no changes required. On the Postfix
side change the 'amavisfeed' entry (or whatever you call it in
a content_filter setting), replacing 'smtp' with 'lmtp' throughout,
e.g. in a service program name, as well as in all its options.
Btw, starting with amavisd-new-2.7.0-pre13 and Postfix 2.8.0,
it became even more comfortable to associate a Postfix queue ID
on each side of a content filter
RELEASE_NOTES:
- added a client-side and server-side support for the IDENT attribute of
a Postfix XFORWARD smtp command (available since Postfix version 2.8.0).
The attribute allows passing of a local message identifier (MTA queue id)
downstream from a front-end MTA to a post-queue content filter and back
to a back-end MTA. Amavisd makes this information available through an
existing macro %Q (which was previously non-empty only in milter setups),
and as such the information appears in the log when using a default amavisd
log template. This information is also passed back to a re-entry MTA if
it announces a support for this attribute (enabled on a back-end smtpd
service with an option smtpd_authorized_xforward_hosts), so the log entries
are now easier to correlate:
back-end MTA:
postfix/smtpd[72995]: 553261D1CB0: client=localhost[::1],
orig_queue_id=2F5971D1CA3, orig_client=...
post-queue content filter:
amavis[20341]: (20341-15) Passed CLEAN ...
Queue-ID: 2F5971D1CA3, queued_as: 553261D1CB0
front-end MTA:
postfix/lmtp[73130]: 2F5971D1CA3: ... relay=127.0.0.1[127.0.0.1]:10024,
status=sent (250 2.0.0 from MTA(smtp:[::1]:10025):
250 2.0.0 Ok: queued as 553261D1CB0)
