This problem might be caused by some content restrictions on your site. If your site is part of a Multisite network, could you check your network settings and make sure that your images are not too large compare to the maximum upload size allowed in the network?
If your site is a single WordPress installation, you will want to check your upload_max_filesize value in php.ini. If you do not have access to that file, your hosting provider should be able to help.
Let me know if it helps.
I also have a problem with attachments.
When I enable Post By Email on the user area, a new email address was created.
If I send a email at that address with text and pictures everything is ok, but if i send a second email the pictures fail an I receive a email from wordpress where is saying that the file could not be moved to wp-content.
If I regenerate a new email address, the same problem, the first goes ok, the second not.
Any sugestion?
All the best.
