Looks like the Xastir list server uses Sorbs anti-spam RBLs, etc. and it
looks like that IP (belongs to Yahoo) has been listed as a spammer.
I've also been having issues with Spamcop listing Yahoo (specifically
pacbell.net) as a spammer and I don't entirely disagree with this
finding. Yahoo's systems have been allowing automated spamming for
sometime now and unless they get it under control, I think a lot of
people are going to abandon them.
In your case, it's probably useless to try to follow the links to get
delisted - http://www.sorbs.net/cgi-bin/support as you don't own that
IP. Other than Yahoo working on getting the IP de-listed (file a
troubleticket with them to let them know this has happened), you might
be able to get the Xastir admins to whitelist this (and other Yahoo IPs
or the entire domain).

About half the time I try to send an email to this group I get this failure

failure. My email address is with Yahoo so I have no control over spam that is
sent by others. Am I the only one having this problem?
