Good Afternoon, I have read around about the limits that have been put on servers for sending emails. Is a way to find out the max emails per hour on a server and what the current number that has been sent out per hour (or day) with php?
My service provider has an undocumented limit for new mailboxes. As I found the hard way when I created a new dedicated mailbox for a newsletter. A couple of weeks later with no spam reports the limit is removed.
My ISP has volume restrictions which means that I can't use my private account for newsletters. All the major webmail providers have very strict limits.
