Trying to send a message to multiple Email addresses the Optus Server sends a reply "try again later".
When sending an Email to multiple addresses my Mail Server returns a message that the Email will not be sent and to try again later. After deleting all of the Email messages saved up to that point the Server still refuses after many tries to send the multiple addressed Email. I have explained all of this to the Web provider and have tested the multiple addressed Email using the Severs Webmail service. They finally advised me to check with your support service to see if the problem could be resolved. I have used Thunderbird for many years and I like the software. Can you help me as the problem is driving me mad. Thankyou, Michael Brinsden
