No, it's not a problem, it's standard practice that email admins are
finally figuring out. Simple, in my domain if I can't do a reverse DNS
lookup on you, I'm blocking you.

This is crazy tho, and i have experienced it as well. Went back to ISP
and they say it is a Yahoo problem.
Apparently the work around was to allow Exchange use DNS to resolve and
send mails rather than an IP address. They say quite a few ISP's are
experiencing this problem.

John,
I had a similar experience with en axchange box (actually
exchange has nothing to do with it).
If your DNS provider does NOT have a reverse DNS, yahoo,hotmail,
gmail WILL NOT WORK.
Go to DNSSTuuf.com to check you domain settings

Can you send to any other, non-yahoo external accounts?
Do you have rDNS records set up for your mail server in the
outside world?

Importance: High
Help Listers,
You may recall I posted a question titled "Steps to install a
new Server". Well we put that server into production this weekend and
now I get to fight the fires. In recent testing I discovered that
emails going out to my yahoo.com email address are not being received,
but emails sent to my charter.net email address are!?! Any suggestions
on what I should look for? I looked in my DNS table and I see no
problems. I have an external webhosting company - acomhosting.com and
we did have email going through their site, in fact my users still have
the POP3 definition in their Outlook setup, but it is at the bottom
below our Mailbox.
Why one SMTP email client and not another?
