Server error 452

[#1]

Server error: '452 [email address] too many recipients in last hour'  I am given to understand that there is a plusnet restriction imposed on the number of e-mails I can send in an hour? If this is the case - what is that number?

[#2]

It was originally 150 but I believe it is 250 now. This changed when Plusnet started using cloundmark on their email servers.

I think it's actually 250 per email and 1000 an hour. Both of those values are subject to change though and aren't written in stone.

Thanks for that. I definitely sent a lot.
