Ok -- this is an error I get on the main masterrussian.com website when trying to send email. I am going to attach screenshots that show what it looks like BEFORE sending the email, after sending the email, my OUTBOX, and then what a message looks like when clicked on that is in my outbox. Please let me know if there is anything that I can do to help you troubleshoot this problem.
Also, you should know that masterrussian.com gives three contact email addresses on this website: http://www.masterrussian.com/blaboutus.shtml. NEITHER of the email addresses work.
Screenshot #1 -- before email is sent:
Screenshot #2 -- after email is sent (THIS IS WHERE THE ERROR MESSAGE IS SEEN)
Screenshot #3 -- my current outbox
Screenshot #4 -- clicking on a message that is in my outbox (notice that the body is empty...)
