Retrieves POP3 email server capabilities.
POP3 capabilities are defined in RFC 2449. The CAPA command allows a client to
ask a server what commands it supports and possibly any site-specific policy.
Besides the list of supported commands, the IMPLEMENTATION string giving the
server version may be available.
