This is strange - because i see somone else posted a similar issues just today. My 1.3.8a shop has been operating just fine since it was deployed late last November. I've received orders and utilized the "update Invoice" function to append messages to the orders and to thus notify the customer of the update message. Well, as of today, it no longer seems to work. As soon as i click "update" to the append the message and send to email, I receive a blank screen stating:
"Email Error: SMTP Error: Data not accepted."
Any clue what could do this ...especially since it was working just fine as of last week (when i used it last).
Thanks for any assistance....
