Brian, That domain might have blacklisted you for some reason or they could be rejecting your mail because of few DNS issues. Many mail servers are becoming very strict on RFC's. See below: http://www.dnsreport.com/tools/dnsreport.ch?domain=richmond.com
You need to set up a reverse DNS entry, accept mail from null "<>" senders, and fix the server greeting. I believe the ***0****2****0**** greeting is a Cisco PIX "SMTP fixup" option. You may want to search the archives for "Cisco" or "PIX". This will need to be disabled to correct the greeting. I'm sure some one on the list may have a more definitive answer on this. -Patrick > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Brian > Cunningham > Sent: Wednesday, November 27, 2002 5:54 PM > To: [EMAIL PROTECTED] > Subject: [IMail Forum] Undeliverable to One Domain > > > We have a user who discovered that he, and we, can't send email to one > particular domain. > > All messages come back as undeliverable due to unknown users.
