When trying to send an email to a group (using Bravenet in Outlook) I am receiving a message from the System Administrator which reads...
Server error: '450 4.7.1 : Recipient address rejected: Policy rejection; Message count quota exceeded'
I am having the same problem. I have been having it for about 2 weeks, first noticed it on Valentine's Day. I have an email recipient list of 200 that I send a weekly email to. I just tried reducing the recipients by dozens at a time, each time trying to send. I can only send a message if I have ONE recipient. How am I supposed to run an email list like that? These are people that signed up for the weekly email and expect to get it.
Using Bravenet's mailing list product or your own email?
Blocked by your own email provider or by the recipients'?
For outgoing emails contact the provider directly. If Bravenet you can raise a support ticket.
If it is the receiving email provider then it varies.
AOL have always had a bad reputation for having a low tolerance over inbound mailings targetting multiple customers. BTConnect have tightened up their spam filters and I had a lot of bounces earlier this month from a mailing list that has been running for nearly 7 years.
