Added support for STARTTLS, similar to the way SMTP AUTH is implemented -- if
a server certificate is available, spamdyke takes care of the TLS. If not
but qmail supports TLS, spamdyke passes it through.
Changed the read() and write() calls to the network to use macros named
NETWORK_READ() and NETWORK_WRITE() that are replaced by TLS routines when
TLS support has been compiled in.
Changed the smtp_filter() return codes to use a mask/flag system because the
possible permutations of PASS/INTERCEPT/QUIT with ADD/REMOVE/CAPTURE AUTH
and ADD/REMOVE/CAPTURE TLS and CHILD QUIT/CONTINUE were getting too complex.
Fixed search_file() to match a file entry where the search text matches the
entry completely but the entry has wildcard markers at the start and/or end.
Added TLS support to tests/sendrecv so TLS can be tested from scripts.
Fixed numerous small bugs in tests/sendrecv that were causing inaccurate test
results (false positives and false negatives).
Updated all of the test scripts to make renumbering them easier.
Added a new test script to exercise a small whitelist wildcard bug I found.
Added 10 new test scripts to exercise the new TLS features.
Changed process_command_line() and usage() to print a brief usage message if
no parameters are given.
Changed process_command_line() and usage() to print a brief error message if
a bad parameter is given.
Changed process_command_line() and usage() to print the full usage message if
-h or --help is given.
Changed process_command_line() and usage() to print the version header if -v
or --version is given.
Renamed test_smtpauth_crammd5, test_smtpauth_login and test_smtpauth_plain to
smtpauth_crammd5, smtpauth_login and smtpauth_plain, respectively.
Moved smtpauth_crammd5, smtpauth_login and smtpauth_plain from the utils
folder to tests/smtpauth, since they're only used by the test scripts
anyway.
Added alternate command line options for people who spell "gray" with an "e".
They do the same thing.
Updated the documentation.
