Re: [exim] DATA ACL - Domain substitute ?

Before the ACL Data I have:-

    warn set acl_m2 = $sender_address

In ACL Data I have:-

    warn add_header = X-crap: $acl_m2

and

    accept condition = ${if eq{$acl_m2}{alpha@???}}

but the test does not work. I am attempting to prematurely jump out of
the ACL Data if the sender's email address matches.

The rejection log shows:-

    X-crap: alpha@???

and the sender's mail address is:-

    Charlie Delta <alpha@???>

Please will someone tell me what I am doing wrong? I use Exim 4.63 with
Centos 5.6.

Thank you.

Paul.
