Not any more than others have done years ago.
Getting to >99.9% delivery for a mailinglist is not difficult. Unless you
use it to manage your newsletter distribution.

The trick is: Do not force people onto your mailinglist. Make it a list
were most people are tech-savy (helps a lot to keep problems down and
if there are any, you get usefull reports) and make sure nobody is using yahoo.
Oh and weed out dead addresses early... For any mailinglist that runs more
than a couple of weeks, you'll have somewhere between 0.1% and 1% dead
addresses per month.

The rest is really just configuring your MTA correctly and keeping an
eye on it.

The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
