Hello Tommy, I am also using verizon and had to deal with this problem several months ago. Verizon requires PLAIN authentication ofoutgoing mail. I'm running slackware which uses sendmail as the mail delivery program. If redhat is using something else I can't give you specific instructions. You need to get a hold of cyrus-sasl-1.5.28 and build it to handle the PLAIN authentication. There are many other authentication mechanisms,but Verizon uses to PLAIN method which is probably the least sophisticated one but is used to MS Outlook express. Once you've built the sasl library, you'll need to recompile your sendmail to include the libary. You'll then need to reconfigure your sendmail to enable the authentication. If you're interested in help, you can write me privately so as not to bore the speakup list with the details. Chris
