Sieve filter

Declare the extensions used by the script:

require ["fileinto", "reject"];

Messages bigger than 100K will be rejected with an error message:

if size :over 100K {
   reject "I'm sorry, I do not accept mail over 100kb in size. 
Please upload larger files to a server and send me a link.

Mails from a mailing list will be put into the folder “mailinglist” :

if address :is ["From", "To"] "mailinglist@blafasel.invalid" {
fileinto "INBOX.mailinglist";

Spam Rule: Message does not contain my address in To, CC or Bcc header, or subject is something with “money” or “Viagra”:

if anyof (not address :all :contains ["To", "Cc", "Bcc"] "me@blafasel.invalid", 
header :matches "Subject" ["*money*","*Viagra*"]) {
fileinto "INBOX.spam";

Keep the rest. This is not necessary because there is a “implicit keep” Rule

else {
