I am using a template for my HTML newsletter. Here's how it looks like: http://inovacijuspektras.lt/naujienl...istaigoms.html
For some strange reason, I experience troubles with font size. On gmail, outlook everything works fine, but for example, on squirrel mail: http://www.part.lt/img/a5376aee82be6...6a075b4935.png

As You can see, the size of a text in 2 places somehow gets bigger.

How can I fix this?
