XF 2.2 Exceed Email frequency

[Sanmu]

Hello, a forum like xenforo.com is likely needed to send out more than 1 million emails per day and we have to send out more than 2 thousand emails per day.

Now is the problem:

• Swift_TransportException: Email to mlXXXa@gmail.com failed: Expected response code 250 but got code "550", with message "550 Connection frequency limited "
• src/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:459
  

How does xenforo solve this problem? Do you have the same problem?


Just saw some admins want to turn off this function: https://xenforo.com/community/threads/turn-off-emails.186628/
I would like to say it is a good way to keep in touch with our users.

There is any good and cheap email provider or adds-on that can provide email service?

What kind of forum is that with this kind of volume?! It sounds more like a spam operation.

I can't think of any forum with user activity high enough to generate that kind of email alert volume. You'd need a powerful, expensive server, too.
