    How to allow email in which the "To:" header contains the string "Undisclosed-recipients:;"   ?

    Arshad

      I want to edit M4 File of Sendmail for allowing Undisclosed recipents. Kindly guide the sequence. My current configuration on Sendmail is as follows :

       

      dnl Reject messages that use unqualified names in the From/To header lines

      HFrom:    $>LocalCheckUnqualifiedAddr

      HTo:    $>LocalCheckUnqualifiedAddr

       

      SLocalCheckUnqualifiedAddr

      R$* % $*    $#error $: 553 percent hack not allowed.

      R$* undisclosed-recipients:; $*    $@ OK

      R$* : $*    $#error $: 553 source routing not allowed.

      R$+ @ $+    $@ OK

      R$* postmaster $*    $@ OK

      R$* `MAILER-DAEMON' $*    $@ OK

      R$* Undisclosed $*    $@ OK

      R$* Admin $*    $@ OK

      R$+        $#error $: 553 Unqualified address: $1

       

      LOCAL_RULE_3

      dnl Reject messages that use source routed addresses

      R$* % $*    $#error $@ 5.1.2 $: "553 percent hack not allowed."

      R$* :include: $*    $@ OK

      R$* undisclosed-recipients:; $*    $@ OK

      R$* : $*    $#error $@ 5.1.2 $: "553 source routing not allowed."
