Dear Davide - As you can see from my previous messages I was unable to lockdown the xMail Server based upon the config below. I did discover that SmtpConfig now seems to work after an upgrade from 1.24 to 1.25.
Now , when I attempt to connect directly and type "Mail from:<[EMAIL PROTECTED]>" without prior authentication I get the error message "551 Server use forbidden". Which I guess is what should be expected. When I manually perform an "AUTH LOGIN" and then type "Mail from:<[EMAIL PROTECTED]>" I get the message "250 OK". The reason I'm doing all of this is to pass all my eMail thru Postini. I really would appreciate your help on this. However, Postini is going to only work if I can lock out the spammers from connecting to my eMail server directly as they ignore the MX records. As you know Postini acts as an eMail Relay as follows: Postini MTA In ---> SPAM Engine --> Postini SMTP Out --> My xMail MTA Target eMail Address is [EMAIL PROTECTED] with MX pointing to Postini Postini Address Space: 64.18.0.0 / 255.255.240.0 My xMail MTA: 64.74.149.27 Now keep in mind that I use xMail in an ISP scenario and as such that I don't know the IPs of the eMail clients connecting to the xMail Server from outside thus I need to allow eMail clients to relay. Of course all clients are required authenticate. I assume I can't use SMTP.IPMAP.TAB because of this. Therefore, it seemed to me that by adding the Postini Address space to the SMTPRELAY.TAB I was hoping it would override the need for authentication. Unfortunately, Postini does provide support for authentication as it is simply a Relay. I guess the questions is why is the content of the SMTPRELAY.TAB override the need for SMTP Authentication? Or is their something that I need to do to make this work? The line in the realy file is: "64.18.0.0" "255.255.240.0" Thanks, Hal Dell Managing Partner ePodWorks.net, Inc. ================================ Hal Dell Wrote on: Thursday, April 17, 2008 2:27 PM Hello All... I have an external eMail Server that accepts inbound eMail then relays all of the eMail to my internal xMail Server. eMail Clients wanting to send eMails out will connect to the xMail Server. I want to force any SMTP connections to xMail to require Authentication and the only allow relaying of eMail by the IPs in the smtprelay.tab. The IP Address of the external eMail Server would be listed in the smtprelay.tab so that xMail would accept eMail from the external eMail server without the need for authentication. So I added the following to the server.tab: "SmtpConfig-64.74.149.27,25" "MailAuth" "SmtpConfig-64.74.149.27,8291" "MailAuth" However, if you telnet to the above IP and manually perform the protocol exchange then xMail Server accepts the eMail for the local domain epodworks.net. I was under the impression that if I add the above SmtpConfig it would force authentication on ALL inbound SMTP traffic.
