This is exactly the same change your network people will have to make to support mail from every other system they have. Exchange, Unix boxes, etc all have to do this.
Using DNS is a part of the use of electronic mail in today's world - similar checks are in the standard configuration for sendmail, exim , Exchange, etc and you're asking IBM to make everyone implement an exception to best practices and a documented RFC for convenience sake. It'll be harder to convince your network people to allow this than to do it right in the first place. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
