For over a week now, we face the "Message size exceeds fixed limit" error. As an admin, I have no chance to find out, who's responsible. The username is not included in the log. The user himself likely hasn't noticed at sending time, that his E-Mail wasn't send. Otherwise he would have take action. If he recognizes afterwards, that his email wasn't send, he will blame the mail-app being unreliable. Because I don't know the username, I can't give a hint to the user in question. Now the situation is: an unsure user and a log filled with errors. Perhaps it is a good idea to include the username in the error log until this issue is closed.
