I need to allow relaying for APC UPS, which only has fields for from and to addresses and server name therefore anonymous access is required for this equipment. I looked at http://msexchangeteam.com/archive/2006/12/28/432013.aspxand http://technet.microsoft.com/en-us/library/aa997170.aspx#, but must be missing something obvious as I cannot relay. this is what I did: created a newsmtp receive connector; type custom; added remote network IP (1 only); permission group anonymous; Add-AdPermission -Identity "Relay V" -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights ms-Exch-SMTP-Submit,ms-Exch-SMTP-Accept-Any-Recipient,ms-Exch-Bypass-Anti-Spam what can I do to make this work?

Hi, Try with this parameter alone: ms-Exch-SMTP-Accept-Any-Recipient Leif

actually what I didis working, but I had to restart Microsoft Exchange Transport service for the changes to work
