Email Won't send

Ray Ingram

I used to send a group from my address book with 15 addresses in it.

Now I get this message "Sending of the message failed. An error occurred while sending mail. The mail server responded: mL0anej4od7RfmL0bnCIXh internal error. AUP#SMTP. Please check the message recipient "kissrockssoo@shaw.ca" and try again."

I broke the group into two groups one with 8 and one with seven. I can send to each group individually so I do not understand why the larger group won't go.

Were limits put on at your end?

As the error message is from the server, it's more like a limit is imposed by the server. You should talk to your email provider.
