... but no ETRN (i.e. Send No Signal) means no Collection at all!

Hi - Has anyone in the UK using Demon SMTP mail been able to get the SBS2000
ICW (Internet Connect Wiz)  to configure mail collection OK? Without
tinkering!!!

I've tried 3x install of SBS with test server (see earlier thread) and found
the requested 30-min mail collection was never initiated by SBS (though as
soon as a client went on to the internet to browse, mail was delivered and
sent fine).  With SBS4.5 (and following Mr Grieve's advice at
http://www.southdown.co.uk/users/jgrieve/faq/demonexchange.htm - thanks!)
it worked fine.

Could this be the answer?: with 4.5 No Signal was sent from ExSvr to collect
mail (as I've heard that Demon don't support ETRN?). I noticed with SBS2000
ICW that choosing 'No Signal' meant that the ominous words 'You have chosen
not to download mail' become part of the wizard confirmation script.

So... I reran the ICW, and chose 'Send ETRN'; immediately ExSvr sprang into
action and downloaded mail successfully...

I guess that some change has occurred to SBS/Exchange behind the scenes
following the dropping of the 4.5 IMC from SBS2000.  Or has some one just
decided that Not Sending A Signal automatically means User Never Wants to
Collect Mail... (and therefore mail is only collected when a queue of
outgoing mail is ready to depart). Any ideas?

The problem with the ETRN setting however is this: it does allow a regular
dial up and collection, but there also seems to be permanent data traffic
between here and Demon after connection. Hence the line is not dropped...
Any ideas what this data traffic could be?

I guess if all this fails, I shall have to rely on a scheduled PING to the
internet to act as a collection (and delivery) trigger.


Thanks
