Yes.  But it's not very nice for the servers.  NNTP and IMAP servers do
the access control stuff upon connection, which can be
resource-intensive.

The earliest version of the ... Mozilla? or whatever they were called at

connection-less method which made a news connection for every action it
made.  It DDoS-ed several NNTP servers.

Not that Gnus would have that effect.  >"?
