You need to find out what the program is which in fact modifies your
mailbox to append new emails.  Is it procmail, dropmail or what?  This
information could be in the config file for fetchmail or getmail,
depending on which of the latter pair you use.  Or, these could be set
up to push messages over SMTP (or LMTP), and then you have to look at
the config for whatever is on the other side or the protocol - maybe a
MTA like sendmail, maybe something like dovecot.

Sorry - I didn't invent all this complexity :-P
