while Pascal's answer certainly is where you would start looking, it
doesn't address the issue of how to temporarily change the value while
reading mail and leaving it for everything else. 

I would certainly give defadvice a go - its the quickest and easiest
way to change behavior which cannot be achieved through customize in
the way you want. 

However, sometimes defadvice may not quite give you what you want. For
example, what would be the behavior if your running under X and open
mail in one frame and then got to do some other work in another frame.
It is possible, since the defadvice may not have completed, the
temporary change you enabled for mail is still set. This probably
wouldn't be an issue in this case, but I cannot say for certain, so
mention it anyway. 

It should also be noted there are situations in which modifying a
setting via a non-customize means, such as a setq, may not have the
consistent affect you expect. in fact, you do sometimes see
documentation which says, "Do not modify this variable by hand - use
customize" or something similar. 

However, as defadvice is so easy to do, I'd just do it in *scratch*
and see if it works.
