The situation is this: Scan or Fax to email used to work at a clients office through their previous ISP (Hostcentric). They have changed to COX and have their own Exchange server but now the MFP has problems sending email. Initially we tried using the internal IP address of the Exchange server as the SMTP but that was also not working. We opted to use COX's SMTP "smtp.lvcoxmail.com" and their DNS server 126.96.36.199 -- This did not work either.
Apparently, the Sharp machine does not have any given place to enter a user name/ password for authentication. I am told by Sharp support that most ISPs will not allow communication through their SMTP server without authentication. This is probably why it is failing. I want to go back and try sending through their own email server.
What needs to be configured on Exchange server for it to be able to accept and send email anonymously through it?
