ec_valid_binding_group is a Sieve test that checks whether the specified binding group binding_group exists.

The following example shows how you can check whether a binding or binding group exists before assigning a message to it. Note that the binding smtp-04 and binding group group-c do not exist.

Binding_Group "group-a" {
  Binding "smtp-01" {
    EHLO_Hostname = smtp-01.com
  }
}

Binding_Group "group-b" {
  Binding "smtp-02" {
    EHLO_Hostname = smtp-02.com
  }
  Binding "smtp-03" {
    EHLO_Hostname = smtp-03.com
  }
}

sieve "sieve1" {
  script "set_binding_phase1" {
    source = "/path/to/myscript.siv"
  }
}

and the contents of myscript.siv:

$to = envelope :domain "to";
if ec_test :is $to "foo.com" {
  if ec_valid_binding "smtp-04" {
    ec_set_binding "smtp-04";
  } elsif ec_valid_binding "smtp-01" {
    ec_set_binding "smtp-01";
  }
} elsif ec_test :is $to "bar.com" {
  if ec_valid_binding_group "group-c" {
    ec_set_binding_group "group-c";
  } elsif ec_valid_binding_group "group-b" {
    ec_set_binding_group "group-b";
  }
}
