DeleGate does not initiate polling to any server.  It gateways a
request from a (HTTP) client to a (POP) server, when a client send
a request to DeleGate.  Thus the only way to poll a new email message
is doing "Reload" on a HTTP client (browser).

In a usual HTTP proxy with cache, reloading might be ignored if without
"Pragma", "Cache-control" or "If-Modified-Since" header.  But in the
case of POP over HTTP gateway, no cache is applied thus any reloading
by a client makes a poll to new message.

So the question could be "how often a user of browser pushes the reload
button".  If so, you can automatically do it adding "Refresh" header in
HTTP response message to let the browser do refresh automatically and
