User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030529 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030529 I have a situation where a message won't send because of its content. Reproducible: Always Steps to Reproduce: 1.Save attached html and load into composer 2.Press CTRL-A in the composer window to highlight it all 3.Press CTRL-C to copy everything there 4.Create a new mail message 5.Press CTRL-A in the new mail message text area so as to highlight it all 6.Press CTRL-V to paste in the content from composer 7.Give the message an e-mail address and a subject 8.Press send Actual Results: A window comes up saying: Sending of message failed. Please verify that your Mail & Newsgroups account settings are correct and try again. Expected Results: Sent the e-mail. I suppose this could be because of some interaction with the SMTP server, but other e-mails send just fine. If you cut the table out, the message sends ok.
Hmm, It seems this stems from the fact that when you copy a message from your sent messages folder into composer, composer can end up with mailbox: references in the file, like this: <img src="mailbox:///C%7C/david/Mail/Sent?number=23453816&part=1.1.2&filename=show_details.gif" width="11" height="11" border="0" onmouseover="flipImage('segment5', true)" onmouseout="flipImage('segment5', false)"> If you chop them out, then the message sends.
