No free disk space. ??

When deleting mail I get this message: No free disk space. Use SHIFT+DEL to delete a message.
I also cannot receive any emails if someone sends me photos. What can I do to fix this?

Try using Shift+DEL as described to delete some of your mail posts which contain many attatchements.
