It's typical of Nightmare er..

DreamHost should be DKIM signing outgoing mail from your domain. The mail being from a 'discussion list' has nothing to do with it. There's no reason why they can't do this other than they just don't want to. ... > Sep 13 13:34:01 pdx1-mailman02 postfix/smtp[19918]: A5E3A4C585D: > to=<veronica.m.p...@gmail.com>, > relay=alt1.gmail-smtp-in.l.google.com[173.194.192.26]:25, delay=2380, > delays=2377/2/0.67/0.43, dsn=4.7.0, status=deferred (host > alt1.gmail-smtp-in.l.google.com[173.194.192.26] said: 421-4.7.0 This > message does not have authentication information or fails to pass > 421-4.7.0 authentication checks.

The SPF may help, but the mail should also be DKIM signed. Also, without seeing the complete raw message headers as received from the list (when viewing a message in the Gmail web UI, click the 'more' icon - 3 vertical dots - and 'show original') I can't be sure, but there may be DNS issues. I.e., the IP address for list.psychdogpartners.org is 64.90.62.213, but a reverse lookup of that IP points to listserver-moon.dreamhost.com. DreamHost should be doing all the right things by default, but it appears they may not be. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
