just want to inquire about smtp relaying. we dont have any mail server we
are just acquiring it from a company that host email and web. any way my
question is about this relay. Each email has a limit of 250relays per
day.
When this is reached we can't send out any email. How does this relay
works. Any information about this would be a great help.


You'd be better off posting this to one of the Exchange groups - see
http://www.microsoft.com/exchange/co...y/default.mspx.

Well, that's assuming the mail host is running Exchange, isn't it? Not an
assumption I'd make on the original post. That said, I'd say it's done just
by saying 'This email address sent a message, add one to the counter' and
then, at midnight, the counters are all reset.

And *that said* if the reason you're trying to figure out how it works is to
game the system so you don't have to worry about such limits, I'd say 'Start
hosting your own mail.'
