Applications :: Links Not Correctly Working And Images In Replied Email?

I am having two problems with the Mail app that perhaps you all could help me with.

First, when I send out emails with links in them, 50% of the time the link is cut in half; the text is there, but the clickable part of the link is only for half of the test.

For example it would show up like this:

[URL]

I know the recipients can just copy and paste the whole email, but I send these emails to a lot of family friend members who aren't computer literate. Plus it's just a hassle for the reader.

My second question is that whenever I reply to an email, my emails don't display the image that was in the original email. It just says "attachmentXXXX" at the bottom. Is there anyway to fix this?
