I have to reject office files for a certain domain plus notifying the
original recipient about the rejection too.
require ["fileinto","reject","body","enotify","variables"];
if allof (address :contains ["To","TO","Cc","CC"] "@example.org", body
:content  "application/msword" :contains "") {
set "to" "${1}";
The set does not work in allof with an other condition, so I use now:
if address :contains ["To","TO","Cc","CC"] "@example.org" {
set "to" "${1}";
}
...
        # :matches is used to get the value of the Subject header
if header :matches "Subject" "*" {
set "subject" "${1}";
}
# :matches is used to get the value of the From header
if header :matches "From" "*" {
set "from" "${1}";
}
notify :message "Rejected Office Datei ${from}: ${subject}" "${to}";
The notify needs as argument "mailto:${to}".
...
        reject text:
Aus Sicherheitsgründen nehmen wir keine Office Dateien mehr an. Bitte
senden Sie uns ein PDF.
.
;
}
A manual sievec call gives not error and if I remove everything but the
reject line it works.
Any ideas?
I used the sieve-test binary to figure out why it was not working.
My full script for checking mime-types as well as extensions and also
notifying the orginal recipient is now the following:
require [ "foreverypart", "mime",
"fileinto","reject","body","enotify","variables"];
if address :contains ["To","TO","Cc","CC"] "@example.org" {
# :matches is used to get value of to, subject and from
if address :matches ["To","TO","Cc","CC"] "*" {
set "to" "${1}";
}
if header :matches "Subject" "*" {
set "subject" "${1}";
}
if header :matches "From" "*" {
set "from" "${1}";
}
        # reject based on mime-type
if allof(body :content  "application/msword" :contains "",
body :content  "application/msexcel" :contains "") {
# send notification to original recipient
notify :message "Rejected Office Datei von ${from}:
${subject}" "mailto:${to}";
# send rejection message to sender
reject text:
