That was my point. My mail IS filtered outbound. So I should have to pay
double for the privilege of controlling my own email? How about this...I
send an email to a client via my isp's mta. There's a problem, but I don't
find out about it for 5 days. I lose business. On the other hand, I send
the email direct, I've got my installation set to notify me of problems after
minutes, not days. I can do that because I'm my only customer. I know
nearly every email that gets sent out and can be very responsive to problems.
I should double my fee for that single advantage? Not sure I buy that.
That's a microsoft-type business plan.
