If you are doing this in the postbit, I think you may be able to just use the variable $forumid. And you should combine your conditions:

<if condition="!in_array($forumid, array(103))">
 do something
<else />
 else do something else
</if>

And, if it is just one single forum, you may want to just go:

<if condition="$forumid != 103">
 do something
<else />
 else do something else
</if>
