Not inside Postfix itself. Postfix code that knows about queue IDs
and other email-related context is 1-2 layers away from the code
that does the lookup; that code knows nothing about email at all.
However, Postfix does make information from multiple layers available
for policy decisions:
- The policy protocol (www.postfix.org/SMTPD_POLICY_README.html),
- The Milter prototool (www.postfix.org/MILTER_README.html). Milters
can be implemented in C, Python, Perl, PHP, and other languages.
- Other external content filters.
