Certainly.


Over the past few years Yahoo has instituted a policy that says, in
effect, if our server did not originate this message, and it has a
yahoo.com sender ( From address ), do NOT deliver this message.

Because some of our users have yahoo.com e-mail addresses, and they send
e-mail from our server, if they encounter a yahoo.com server, the mail
stops and is dropped on the floor.

Most of the e-mail that I am concerned with is Customer Service e-mail,
which becomes an issue if it isn't delivered to Customer Service!

To get around this, I moved their address from the From field to the
ReplyTo field, so that Customer Service can still get back to them, but
Yahoo doesn't seem to complain. ( this week! )
