The question is quick, but there's not enough information to give a good answer. It all depends. Sure, it's cleaner if you have just one module to do the task, but is it worth the trouble to modify your existing situation? Do you often have to change 2 or more of those 6 scripts with the same modification? If so, you might be better off putting it all together. But then, if it's simple sending out mail, how often is that going to change? It's not that one is replacing MTA's with MTA's with a different interface every other week.
