Sorry, Alexey, I neglected to answer this in my previous reply.

RFC 1734 doesn't specify an optional second parameter.  RFC 2222 does
mention it, but does not say it should be base64 encoded; it talks
about binary tokens.  Because POP is not a binary protocol, it makes
sense to specify that the parameter (initial response) be base64
encoded.
