Procmail is a local mailer. Once your MTA (such as Sendmail, QMail, 
PostFix) decides to deliver a message locally (to a local mailbox), it 
hands the mail over to a local mailer. This can be procmail, but also 
(for example) Cyrus.

Once fetchmail fetches your email, it'll send the mail to the host it is 
running on on port 25. The man page is clear on that:

        As each message is retrieved fetchmail normally delivers it via 
SMTP to port 25 on the machine it is  run-
        ning on (localhost), just as though it were being passed in over 
a normal TCP/IP link.  fetchmail provides
        the SMTP server with an envelope recipient derived in the manner 
described previously.  The mail will then
        be  delivered  locally via your systemâs MDA (Mail Delivery 
Agent, usually sendmail(8) but your system may
        use a different one such as smail, mmdf, exim, postfix, or 
qmail).  All  the  delivery-control  mechanisms
        (such  as .forward files) normally available through your system 
MDA and local delivery agents will there-
        fore work automatically.
