With the release of Exchange 2003 SP2, many organizations will begin using Sender ID as part of their anti-spam tool kits. Add appropriate DNS records to your domains to support this and avoid having mail end up in the junk mail folder!
From http://blogs.technet.com/technet_uk_-_exchange_tour/archive/2005/11/23/415004.aspx:
If you have Exchange 2003 SP2 running on any SMTP hosts in your organization, you can enable Sender ID checking on inbound mail, but even if you don't, you can publish a record of all your SMTP servers in your own DNS, so that if someone receives mail from you and they choose to enable Sender ID checking, then they will be able to positively identify your mail and may be less likely to filter it as junk mail.
