I too am having this problem and getting this error message when I try to send an email with an attached photo to myself from my cell phone.

smtp;552 5.2.2 This message is larger than the current system limit or the recipient's mailbox is full.
You say to "open windows mail on the computer"  then click on "tools"   Forgive my stupidity but I don't know how to do this!  Can you give more detailed instructions?
Thanks!
