re: mail config
I thought I sent to the list, alas, only Albert, sorry. Here's
a resend.

Yeah, mixxx.org's mail is not configured right. Should be an
easy fix though. Here's an area I can contribute to mixxx :-)
DNS I know.
from splatter.wps.com's mail/err log, line breaks added by me
for readability:
Feb 21 10:00:00 splatter postfix/smtpd[21697]:
NOQUEUE: reject: RCPT from 208-78-101-139.slicehost.net[208.78.101.139]:
504 5.5.2 <stacktrace>: Helo command rejected: need fully-qualified hostname;

helo=<stacktrace>
My server says: your server claims to be mixxx.org, but is
really 208-78-101-139.slicehost.net, pants on fire, go away.
*** The very first line of defense against spoofed hosts is
consistent cross-checked DNS, since that's very hard to fake up.
My server is not logging alleged HELO names, so I can't
tell you what it says it's name is, but likely it's
saying "208-78-101-139.slicehost.net".
Your MTA is
208.78.101.139 which maps to
208-78-101-139.slicehost.net which maps to
208.78.101.139 so that's clean.
You can fix this one of two ways:
ONE:
You have an A record that says mixxx.org is 208.78.101.139,
but an in-addr lookup of 208.78.101.139 does NOT return
"mixxx.org". Add a resource record to zone file mixxx.org
that does
139.101.78.208.in-addr.arpa IN PTR mixxx.org.
(The receiving MTA will get a HELO from mixxx.org; will look
up mixxx.org and get 208.78.101.139; will lookup in-addr for
208.78.101.139 and get { 208-78-101-139.slicehost.net, mixxx.org }
and be happy.)
TWO:
REMOVE the A record for mixxx.org.
ADD a mail host, say "mail.mixxx.org", add add it to the mixxx.org zone
as a CNAME
mail.mixxx.org. in CNAME 208-78-101-139.slicehost.net.
(The receiving MTA will get a HELO from mixxx.org; the resolver
will lookup mixx.org and get CNAME 208-78-101-139.slicehost.net;
it will look up 208-78-101-139.slicehost.net and get
208.78.101.139; it will look up 208.78.101.139 and get {
208-78-101-139.slicehost.net } and be happy.)

You have a bunch of google names as MX hosts, I hope they don't
send mail for "mixxx.org", that would complicate things. Likely
it's just the forum/wiki though.
Last, I strongly suggest that you comply with the irritating
and kludgey SPF crap, used by public cesspools like AOL. It's
easy enough to do though.
In your mixxx.org zone file, add in the appropriate place:
mixxx.org. IN TXT "v=spf1 ip4:208.78.101.139 ~all"
AOL is a MAJOR PITA when it comes to accepting mail from
lists. You have to sign up, kiss their ass, swear allegience,
blah blah, then MAYBE tey will accept list mail... oh, and if ANY
ONE CUSTOMER complians or puts your mail in their SPAM folder,
then you are marked as unclean.
