Hi Brian. I'm glad you were able to go. It's always nice to have 
someone around who's been on the list since the beginning. I like 
learning about the history of the list.

I checked out the Murphy colorscheme in vim, and it's actually 
better than I remembered it. I've been using moria [1] in gvim 
and xoria256 [2] in vim.

Whew! I was worried that I might have missed something obvious. 
I'll implement this over the weekend and post back here how it 
all turns out.

So the first line in this one specifies that the given username 
and password will be used for smtp1.example.com because that is 
domain specified in the relayhost map, right?

*Thanks* again, *that* was *very* *helpful*. ;-)
