SSL and IMAP

I'm using Mail::IMAPClient to write a mail filter via IMAP.
I'd like to connect to the server using SSL.
The instructions in the man page don't help me:

$imap=Mail::IMAPClient->new(User => $user, Password => $pass, Server =>
$host);
# blah blah blah (doc's blah blah blah, not mine!)
$imap->Socket($ssl);

Can someone give me a pointer in the right direction? I assume I need to
also use an SSL module (IO-Socket-SSL?), but some pointers to fill in
that # blah blah blah would be terrific.

Also, if there's a better module than Mail::IMAPClient to do IMAP and
SSL, that would be great, too.
