Some people have already mentioned using various forms of VPN, but there are also other products that either plug-in to Exchange 2000, or act at a gateway between Exchange and the Internet.
We use MailMarshal from Marshal Software (recently acquired by NetIQ), which is a great product, supporting mail filtering as well as gateway to gateway encryption, plus a host of other features. It can either be integrated with Exchange2000, or act as a relay between the Internet and Exchange (5.x or 2000). http://www.marshalsoftware.co.nz/ Just my 2c > -----Original Message----- > From: Al Cooper [mailto:[EMAIL PROTECTED] > Sent: Tuesday, 1 April 2003 5:44 AM > To: [EMAIL PROTECTED] > Subject: Email Encryption Between Servers > > > We are attempting to set up secure e-mail with our partner > companies to > comply with the upcoming HIPAA requirements.
