I have tried to REPLY to e-mails from Lou HART about DNA HART testing. The most recent this morning. The 3 messages have been returned undelivered as "Invalid Recipient". Lou, please check your Comcast account. The messages do come from your Comcast account, I haven't any idea how this problem can exist. Here is the actual message: Reporting-MTA: dns; comcast.net Arrival-Date: 17 Oct 2004 11:03:10 +0000 Final-Recipient: rfc822; <louhart@comcast.com> Action: failed Status: 5.0.0 550_Invalid_Recipient Diagnostic-Code: smtp; Permanent Failure: Other undefined Status Last-Attempt-Date: Sun, 17 Oct 2004 11:03:10 -0000
