marker for unique emails?
is there something in the email-header which is guaranted to be unique.
i want to avoid double emails,
like when i download my mails multiple times while
testing, without removing them from the server.
now i look for a way to identify the doubles without much overhead,
so i want to cache a reliable "checksum" in a file.
currently i use checksum , skipping first two lines
(they change, "received" with changing date).
after that i double-check with my archive if equal.
which may work only with my provider?
