Unlimited Mass Email through my own SMTP server

Unlimited Mass Email through my own SMTP server

I have read many requests for possibility to use unlimited mass emails through customer SMTP server.

Unfortunatelly - ZOHO CRM still does not have this option to send the mass emails through the customer SMTP server.

Here is last ZOHO answer (in another topic) from 21.Dec.2009:
"But we will analyze this in our future updates. Also, we are planning the update our email editor in our future updates."

But I have read simillar ZOHO answers from 2008 to 2009 year.

My question 1: WHEN it will be possible ?
My question 2: WHY is it such big problem ?
