Thanks for your response. Here is the output of my telnet test. I guess I'm really not sure what to make of it. The bolded text is of some concern to me. pc130:~ admin$ telnet mail.ipr.edu 25 Trying 66.226.64.2... Connected to mail.ipr.edu. Escape character is '^]'. 220 pro.abac.com ESMTP Sendmail 8.14.1/8.14.1; Fri, 11 Apr 2008 12:27:30 -0700 (PDT) helo abulafia.ipr.edu 250 pro.abac.com Hello 75-146-145-253-stlouispark.mn.minn.hfc.comcastbusiness.net [75.146.145.253] (may be forged), pleased to meet you mail from:[EMAIL PROTECTED] <[EMAIL PROTECTED]> 250 2.1.0 [EMAIL PROTECTED] Sender ok rcpt to:[EMAIL PROTECTED] <[EMAIL PROTECTED]> 550 5.1.1 [EMAIL PROTECTED] User unknown
Thanks again. I'm not necessarily looking for someone to give me the answer, as it were, but if I could get some help looking in the right direction I would be very appreciative.
