this is rare but does occur from time to time. I do not know how to reproduce

i use a simple script sieve
of this style
~]$ cat  .dovecot.sieve
require 
["fileinto", "mailbox" ,"reject", "regex", "variables","envelope", "subaddress"];
# rule:[perl]
if anyof (header :contains "Return-Path" "perl.apache.org",

{

        stop;
}
