protect against xss attacks

I'm having my mailforms send as plain text mail without the use of htmlentities. As I mail reader I'm using either:

webmail (squirrelmail), which processes them with htmlentities itself anyway, so even if it is displayed as "plain text", it's actually shown as html but with html entities in the "source" so tags/scripts in the message are shown as their original characters without the danger of them being executed

 

or:

Thunderbird, which shows plain text always as plain text, not as html (that's true, isn't it?), so any tags/scripts aren't executed anyway.

 

Am I now protected enough against xss attacks?
