Notice the extra word 'level' just to the right of the less-than symbol.

Hi Jim
Using the github "blame" feature on file global/mail_params.h it was
easy to track down when this was introduced:
postfix-3.6-20210109
From the history file:
20210102
Infrastructure: support for the <=level, <level, and other
operators to compare compatibility levels. With the standard
<=, <, etc. operators, compatibility level 3.10 would be
less than 3.9 which is undesirable. Files: global/compat_level.[hc]
and test files.

Hi John, Thanks for the quick response and details. When I upgraded the
system to postfix v3.6 it complained with the following error, however
it has since resolved itself once I set compatibility_level=3.6.
postfix/smtpd[3751]: fatal: in parameter smtpd_relay_restrictions or
smtpd_recipient_restrictions, specify at least one working instance of:
reject_unauth_destination, defer_unauth_destination, reject, defer,
defer_if_permit or check_relay_domains

Jim
had you previously set a compatibility_level in version 3.5 or left it
at the default? Was the compatibility_level the same when you got the
above fatal message in version 3.6? Did you make changes to
smtpd_recipient_restrictions between version 3.5 and 3.6
The logic behind that fatal message is that you can have an empty
smtpd_relay_restrictions (like you would get if you left defaults for
smtpd_relay_restrictions and compatibility_level) but in that case you
have to have one of the required restrictions in
smtpd_recipient_restrictions.
I don't see changes in that logic between version 3.5 and 3.6.
John
