SMTP Service not available...

[Gaacnews]

I cannot remember the error number, maybe it was 554, but it said SMTP service not available. This is after sending 350 of 400 e-mails.

Could it mean that my ISP has restricted my access because of the number of e-mails being sent?

Very likely. Try to use a slower rate, less connections, a group and an interval. The best would be to know more about that delivery limit in order to set MaxBulk Mailer accordingly.
