The example under the "Action append" definition was incorrect; here is the
correct
example.
if allof( header ["To"] :contains "ietf-mta-filters",
not header ["X-Filed"] :contains "ietf")
{
append :new :header "X-Filed" "ietf"
fileinto "Lists/IETF"
keep
}
The example under the "Action replace" definition was also incorrect; it
should read:
if allof( header ["To"] :contains "ietf-mta-filters",
not header ["X-Filed"] :contains "ietf")
{
if not header ["Subject"] :contains "[IETF]" {
replace :header "Subject" "[IETF] $SUBJECT"
}
append :header "X-Filed" "ietf"
resend "Local-IETF-List"
}
The above example modifies the original Subject header by inserting a
list
identifier into the subject.
