kernel upgrade probably not very important. As others have pointed out, 
there is little reason not to upgrade MS and SA. Stick as much memory in 
the box as it can handle.

if you are "inundated" then the best start you can make is to reject as 
much as possible at the MTA. As this is Debian, your MTA is probably 
(but not necessarily) exim. Look at putting in a single well regarded 
block list at the MTA, something like but do your 
research and find one that /you/ like the look of (block list 
preferences can start flame wars!). Make sure you are rejecting mail at 
the MTA for all unknown recipients and not accepting then bouncing. Set 
up your MTA to throttle incoming mail so it doesnt get overwhelmed or 
let your incoming queue build up uncontrollably.

Visit the MS wiki for tips on how to do this - dig deep, it can be a bit 
tricky to find what you are looking for. Search the archives for good 
links into the wiki.
