    I have thousands emails in my spam folder of xenforo's default email address that I never noticed until now. All of them are related to hotmail/live and a few are yahoo.

    Here are a few different types that I see.

    Code:

    In this case I think this was the same user that tried 2 different ip addresses.

    Here is different error.

    I also occasionally receive an email stating that a message could not be sent for the past 4 hours and that it will try for 5 days.

    Are there some settings I need to change that will limit or solve this problem?

    I had similar errors and returned mail because of a spam flag. What had happened was, on shared hosting, some other customer using the default PHP mail had been sending spam. The IP address was then blacklisted. If you follow the instructions in the returned email you can usually see which list you're on and request removal, but that is often only a temporary fix and it's worth contacting your host.

    In the end I changed from using the default sendmail to using a standalone mail account and this seems to have fixed it.
