Which mail clients don't do SMTP auth?

Agreed. But it is a necessary workaround until all mail clients 
support SMTP Auth. Sorry Bob Minor, for using your name in vain. I 
was a Bob Minor when I first used PO. Fortunately for me, was not 
caught by the RBLs before I learned from this list about the dangers.

Bob, I had verizon dialup (when it used to be gte.net) for years and 
then they changed their smtp server to ONLY allow their users to use 
it IF their return address ends with @verizon.com. That made it 
impossible for me to use. PLUS, they will not let you use any OUTSIDE 
smtp server to send mail. So after talking to everyone I can in their 
support group, I had to cancel my account and switch to Earthlink, 
which will tolerate a return address not ending in @earthlink.net.

So, as long as the ISP world is in constant flux, the only solution 
for email providers like us to offer our users universal access to 
their email (send and receive) is to either switch from PO to a 
program like Kerio or CGP that offers integrated Webmail or learn to 
play games with SMTP auth or faking it.

Thanks to PO, my life is much improved and no users have complained 
about not being able to send mail from any kind of weird combination 
of email clients and connections.
