Logical expressions

Logical expressions enable the evaluation of one or multiple conditions using boolean operations such as AND, OR, and NOT. The following logical comparators are available:

• all-of: Represents the AND operation and returns true only when all conditions return true.
• any-of: Represents the OR operation and returns true if any of the conditions return true.
• none-of: Represents the NOT operation and returns true if none of the conditions return true.

These logical comparators are represented as TOML arrays that contain the conditions to be evaluated, for example:

.. [ { any-of = [ { if = "authenticated-as", ne = "[email protected]" },
                  { if = "rcpt-domain", eq = "example.org" },
                  { if = "mx", starts-with = "mx.some" } ], then = .. 

.. [ { all-of = [ { any-of = [
                      { if = "authenticated-as", ne = "[email protected]" },
                      { if = "rcpt-domain", eq = "example.org" },
                      { if = "mx", starts-with = "mx.some" },
                  ] },
                  { all-of = [
                      { if = "rcpt-domain", eq = "example.org" },
                      { if = "listener", eq = "smtp" },
                      { if = "mx", starts-with = "mx.some" }
                  ] },
                  { none-of = [
                      { if = "rcpt-domain", eq = "example.org" },
                      { if = "listener", eq = "smtp" },
                      { if = "mx", starts-with = "mx.some" }
                  ] }
              ] }, then = ..
