Is there a recipe for detecting messages in which the body is empty?
The following recipe doesn't work, because (according to the verbose
log) the "< 2" condition doesn't match.
:0
* ^From.*(root|backup)
* ^TOroot
{
# Delete all having no message, no subject
:0
* ! ^Subject:
{
:0B
* < 2
/dev/null
}
# Other stuff deleted
}
What version of procmail is this with? The HISTORY file mentions a
bug in the handling of '<' and '>' conditions when it was applied to
variables, but that may also effect it's handling of the B and H flags:
1995/10/29: v3.11pre4
Changes to procmail:
- varname ?? < nnn conditions didn't have the expected effect
Alternatively, the following should work:
{
:0
* B ?? ^^(..?)?^^
/dev/null
>
The '^^' token matches either the very beginning or the very end of the
string being matched, here, the body of the message.
