I've temporarily turned it off anyway ... need to figure out a better way 
of doing it ... 'submissions' aren't a big issue, as the delay for 
greylisting is minimal ... the problem is that majordomo has feature in it 
that auto-unsubscribes ppl from the list if their email bounces over N 
times ... so, if we send out an email through pgsql-general to 1000 
subscribers, and 100 bounce back (reasonably normal), those 100 are all 
"new" to the greylisting system, since the return addresses are all 
*individual* (<listname>+<unique identifier>@postgresql.org) ... server 
load wasn't being affected, but the mail queue on the MX servers were 
being bogged down fast, since they were trying to resend *through* the MXs 
...

Need to get all the MXs setup first, *then* the main server, so that the 
MXs see it as the 'second attempt' and bounce it straight through better 
...

Will let y'all know once I have this setup a *wee* bit better to deal with 
majordomo's "ACKs" ...
