1 This list does not really follow priority.
3 * Code cleanup: split smtp_session.c into generic SMTP, legacy TLS,
4 and current TLS. The amount of TLS code now dominates the file.
5 Do this after all other code revisions stabilize, to avoid
6 complicating code reviews.
8 * Code cleanup: TLS_LEV_NOTFOUND no longer belongs in the TLS
9 library. It is an SMTP-client only feature. To fix, change the
10 policy lookup API and use a different method to indicate if a
11 policy was found. At the same time, fix policy lookup to initialize
14 * Code cleanup: see if multiple consecutive switches can be aggregated
15 (set_cipher_grade() and session_tls_init()).
17 * Implement support of CRL checking. OpenSSL 0.9.7 finally supports CRLs,
18 so Postfix/TLS should support loading CRLs.
20 * Cleanup the "pfixtls" special logging, so that it fits Wietses original
21 "per site" decision to make debugging easier.
23 * Move TLS based information from separate lines into Postfix's smtpd
24 logging lines to make logfile analysis easier.
26 * Check the "info_callback" for sensitive use. I already had to remove the
27 "warning alert" issued on normal shutdown. Why is a warning issued for
30 * Introduce new tls_per_client table to achieve the same selective behaviour
31 for incoming connections.
33 * Introduce better support for "opportunistic" encryption: collect information
34 about peers connecting; log warnings when the key changed etc.
35 [I am not sure that I already have the best answers available.]
37 * Find a way to use the certificates themselves instead of the fingerprints
38 to allow certificate based relaying. The maintenance of the fingerprints
