The voice of "Jim Thompson" drifted in on the cyber-winds, from the sea of virtual chaos...
I went the same route over 2 years ago. One of the things I like about my domain host is the ability to set several email aliases per account and still having a proper "name not found" sent to any aliases I've "decommissioned" or haven't created yet. In total I only have three accounts, but few dozen aliases spread across them.
As for a DLA account, there's no real reason to bother with one. The only thing mine collected was an ever-increasing amount of spam, so after the fall out of Swen I ditched it in favor of a monthly "viral-ignored" address for my Usenet posts.
