xnntpreply()

static int xnntpreply ( const struct server *  current_server, int  may_auth  )

static

decode an NNTP reply number reads a line from the server and returns an integer

498 is used to mean "protocol error", like smail, and includes timeout and "server disconnect" (EOF) conditions

the text returned is stored in lllen/llstr for later retrieval by lastreply()

from Tim Sweeney: retry in case of AUTHINFO failure.

Parameters

may_auth

set this to true to enable authentication after 480 reply
