You obviously missed the FAQ about the information needed :-)  I'd
point you at the online one, but currently the people that host the
fetchmail website are off the air.d

You're over complicating the solution, honestly.

Yeah, read the man page :)

Try the UIDL option (as specified in the description of the "keep"
keyword in the man page).

UIDL is the *ONLY* way forwards if you're using POP.  Without it then
the server tracks state, which isn't what you want.  Quoting the man
page:

| (Keyword: uidl) Force  UIDL  use  (effective  only  with  POP3).
| Force client-side tracking of 'newness' of messages (UIDL stands
| for "unique ID listing" and is described in RFC1939).  Use  with
| 'keep'  to  use  a  mailbox  as  a baby news drop for a group of
| users.

This is already a fetchmail default, there's no need to specify it.

For a (2 line) shorter .fetchmailrc you may as well specify pop3 as
the default protocol since all your remote servers use it.
