"Greetings" -- sendmail block

[Julian Field]

In case you want to block this with sendmail, so that it never gets in to
your site in the first place, this will do the job in your sendmail.cf file:

HSubject: $>Check_Subject
D{FriendPat}you have an E-Card from
D{FriendMsg}This message is probably a nasty E-Card.
SCheck_Subject
R$* ${FriendPat} $*             $#error $@ 5.7.1 $: ${FriendMsg}

Remember that the whitespace before "$#error" has to be tabs and not spaces.

If you want to expand the list of subjects, just make more pairs of "D"
lines to set the patterns and messages, and add a new R line for each one.
