You'd have to trim the message header to drop some of the "Received" headers.
One way to do that is to add header checks to match just the headers added
during the loop, and to raise the maximum hopcount temporarily so that
cleanup will accept the messages, but drop the excess headers to prevent
triggering similar limits downstream.
First test the header checks with:
# postcat -h -q <queue-id> |
postmap -h -q - pcre:/path/to/header_checks
Just the unwanted headers should trigger an "IGNORE" action.
This needs to run as "root" or "postfix" to read the queue files. If you
don't have or use PCRE, use "regexp".
