Re: [Exim] ACL Spam Rejection Tricks

Thanks for the help. Here's what I ended up doing to require a subject
exist. It gets rid of a lot of junk.

deny    condition     = ${if def:h_subject: {no}{yes}}
    message       = Message Rejected - Subject Header Missing

deny    condition     = ${if match{$h_subject:}{.+}{no}{yes}}
    message       = Message Rejected - Subject Required
