For saftey reasons Postfix programs will log only a limited amount
of mesasage content, to avoid logfile spamming.

The cleanup_act_log() function logs logs up to 200 characters. The
SMTP client's smtp_hbc_logger() function was added 10 years later,
and it logs only 60.
It does not matter what the number is, you just cannot asume that
Postfix will log all headers in their full glory. It just is NOT
SAFE.

There is no such feature. Fortunately, computers can do the work
for you and combine different logfile records from the same mail
transaction. In Postfiox source code there is a collate tool that
can serve as a starting point.
