I haven't looked at the details of this particular error, but are you
using an alias'd address? For example, my return address here is
@users.sourceforge.net. However, they only resend mail to that address
to my real address @frontier.com. I have validated to frontier.com
that I really do own the address @sourcegforge.net. So I send through
the frontier server with a From: address of sourceforge.
I find this excerpt from cygwin-help a bit confusing. Notice the
"yahoo.com" in the "Remote host said:" message. What's really going
here? Why is yahoo.com doing the authentication for a gmail.com

Hi. This is the qmail-send program at sourceware.org.
I'm afraid I wasn't able to deliver your message to the following
This is a permanent error; I've given up. Sorry it didn't work out.
User and password not set, continuing without authentication.

In my case, with a KDE mailing list, when KDE gets a message, they ask
the domain of the message (sourceforge) about their policy. Recently,
they upped the level, and so told KDE to reject any mail appearing to
be from sourceforge if it didn't actually come from their. Thus I got
lots of this type of error. Someone finally convinced sourceforge that
didn't make sense, since one of their offerings is aliased email
addresses, which were then all bouncing.
So, your From: is gmail. Are you actually sending through a gmail
server, or through a yahoo server? (Note yahoo servers handle all
sorts of other domains, not lease most of the domains used by AT&T as
