Hello all. So I moved my site from one hosting provider to another and the Newsletter function isn't working now. I changed the SMTP settings to reflect the new provider (3Essentials) and when I test the email, I do get the Test Configuration email back so that works. Now, when I create a newsletter to send out, I get an error report back saying it was unable to send to "X" number of recipients. This is what I get back... Any ideas to what could be wrong?

Michael,

I am sure there isa n issue with your SMTP server settings in Host Settings. please validate, that your changes have successfully been saved.

I had a similar problem on my dedicated server (placed at home !) as well.

Reason after some investigating: it was the standard setting of the running mcafee! Almost hidden is a setting "prevent mass mailings..."
