[SECURITY] Fedora 34 Update: fetchmail-6.4.22-1.fc34

Fetchmail is a remote mail retrieval and forwarding utility intended for use over on-demand TCP/IP links, like SLIP or PPP connections. Fetchmail supports every remote-mail protocol currently in use on the Internet (POP2, POP3, RPOP, APOP, KPOP, all IMAPs, ESMTP ETRN, IPv6, and IPSEC) for retrieval. Then Fetchmail forwards the mail through SMTP so you can read it through your favorite mail client. Install fetchmail if you need to retrieve mail over SLIP or PPP connections.
