Host unknown: Not a typewriter > (rest deleted) The Internet host 'ESSEX.ECN.UOKNOR.EDU' has two MX-records: - preference=0, MX= MailHost.ECN.UOKNOR.EDU, - preference=10, MX= OOZ.BACKBONE.uoknor.edu When I connect to the "preferred" MX-host ('MailHost'), and entery 'VRFY cchan', I don't get that message. It's **only** the "secondary" MX-host ('OOZ'), which gives that message. So, I've asked the "postmasters" at UOKNOR.EDU to correct the problem.
