Good day support team, I had this sending message error show on my Thunderbird desktop when I try to send Annual Report to my members. I had tested to send through Bcc to 50 recipients and not sure how many is going through or not even one is going through. This is due to the over limit of the recipients I send through Bcc or recipient "bcl5157@gmail.com" account as show on the attached screenshot picture had problem? For this scenario, is it better to create a Mailing list instead? Thank you in advance. Regards Jim
