Hello,
The Optimum SMTP is recently rejecting emails I am sending from one of three Optimum email accounts that I have. When using the one account I get the following rejection notice:
Sending of the message failed.
An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 6661A65F0037E564). Please check the message and try again.
This only occurs when I use Thunderbird to send messages. If I use Outlook on the same computer, I do not get the error. Previously, I was getting the error on all three accounts, but when I upgraded to 64-bit Thunderbird, the problem went away. Of course, I called Optimum and they said that the problem was on my side and were not helpful. They also don't take any responsibility if you don't use their web interface.
I would appreciate any ideas that anyone has on what I could try to eliminate this problem. Thank you.
