FetchYahoo is a Perl script that downloads mail from a Yahoo!
account to a local mail spool. It is meant to replace fetchmail
for people using Yahoo! mail since Yahoo!'s POP service is no
longer free. It downloads messages to a local mail spool,
including all parts and attachments. It then deletes messages
unless requested not to. It can also optionally forward
messages to a specified email address and repeat with a given
interval.
