Add sending limits per hour/day/month for smtp servers

[infabls]

Many hosting providers and SMTP servers limit the number of emails to be sent per hour, day. Can you add a setting for SMTP servers so as not to exceed the limit?

Thank you for your hard work on this product

This is difficult for us to implement as we have no way of determining how much of the quota remains available. We need to be conscious of the fact that SendPortal may not be the only service sending messages, so it's not enough for us to just define a quota and prevent sending more than that number.
We are also making adjustments to how we handle the SES quota - pushing messages back on to the queue rather than just rejecting the campaign, a change that makes this even harder to implement for SMTP.

We recommend using a proper API email service instead of SMTP.

If, for example, I select an email address that will definitely be used only in the sendportal, can I just check how many letters are sent per hour? I've seen a similar implementation in Windows mailing list programs, but the beauty of the sendportal is that it runs on the server while I sleep.

non-profit projects in developing countries cannot afford to pay dollar bills for using api services. which is a small payment for developed countries, in my country is the average monthly salary
