We say ???might??? because further
try_tls rule set rules are allowed, and access database lookups are performed,
which, in turn, can subsequently disallow STARTTLS:
R $* $@ OK allow subsequent try_tls rule set rules
Your rules, if any, will be called first. That is, for example, if you add rules to try_
tls, those rules will be called before those that were already in the try_tls rule set.
You need not restore the workspace at the end of your rules, however, because that
restoration is taken care of for you.
5.3.9 Additional TLS Help
Getting TLS to work at your site can be a daunting task. In addition to this book you
may wish to investigate the following resource as well:
http://test.smtp.org/
As of this writing, mail sent to bit-bucket@test.smtp.org will be accepted, discarded,
and logged (with the logs visible via HTTP). Visit that site for details
about how to use that address to test and validate your TLS setup. But note the
warning on that site: ???Do not use this machine to monitor your SMTP connectivity.
It is for SMTP interpretability testing only!???
* Actually, $#anything will have the same effect, but you should use $#OK only to remain compatible with
future releases of sendmail.
