Thanks for the plain text format tip. I have resolved the DNS issue I was having but now I am getting another message when I send to the listserv server internally for testing. This is the message I get; The following recipient(s) could not be reached: [log in to unmask] on 10/24/2002 11:46 AM The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address. <netvista-dc.netvista.ca #5.1.1> Any idea how to get around this since Exchange 2000 seems to require verifying a recipient name before forwarding it?

Recent versions of some email clients allow you to set a flag in an address book entry to specify whether messages for that address should be plain-text, HTML, or mixed. If your email client software supports this feature, you may want to consider creating an address book entry for your listserv server command address, and flagging it as a "plain text" message recipient. -- Paul Russell Senior Systems Administrator University of Notre Dame
