Telus mail certificate expired?

[wireless]

When I go to create my Telus email account in Apple Mail, I get an error saying "Mail can't verify the identity of the server "imap.telus.net"." When I click the "Details" button to look at what's going on, it shows that the "Go Daddy Secure Certificate Authority - G2" certificate expired at the end of August. Did Telus mess up here, or is this normal...?
