Can your smart host's configuration be modified? or is it your ISP's server?

The smart host is thus delaying delivery of those message by up to 15 minutes as it thinks it's bulk mail (for info, it rejects mail after 10 messages in any single connection). On Exchange 2003, there was a nice setting called "Maximum messages per connection" on the SMTP virtual server tab which now, unfortunately, seems to be absent. Does anyone know a) How many messages per connection Exchange 2007 can submit, and if that value can be changed; b) If not, a creative solution of how to get around this, bar accepting the 15 minute delay, or making unwanted changes elsewhere? Cheers Richard
