Postfix can log SMTP commands and responses, but not the message
content because that would consume huge amounts of resources.
If you need the entire SMTP session, your options are
- A network-level sniffer (tcpdump -s 0 -w /file/name ...).
- An SMTP-level splitter (configured using Postfix's smtpd_proxy_filter)
that sends one copy of the SMTP stream to an archival server, and
one copy to Postfix itself.
Either way, no turn-key solution.
