Hi again,

I am using the Indy SMTP classes, and now I am getting this error on the
mail server (SATA - 502).  I should also note that I was getting the same
error on when I used the CDO wrapper in the .NET Framework (SmtpMail class).
Here is the server log:

Any idea what in the world might be causing this?

Thanks,
Jeremy
