Issues After Upgrade

Actually I am facing issue after upgrading domino from version 7.0.1 to r8.5. the Domino server is placed in DMZ area. In old environment the domino server was having two network interfaces, one was connected to DMZ (IP Address 192.168.20.1) and the other was connected to internal core switch (IP was 10.10.3.24). all the LAN users were connecting direct to domino server. I upgraded domino server from version 7.0.1 to r8.5 then they removed internal link (disabled the NIC which was connecting directly to the internal core switch) due to security reason. Now all the LAN users and servers are connecting through firewall and not direct. They have bind the LAN users request which is coming through IP 10.10.3.* to one IP address which is 192.168.20.48 (the DMZ IP Address) and the LAN servers request which is coming through IP 10.10.4.* to one DMZ IP Address which is 192.168.20.2 to send and receive email though Domino Server which is placed in DMZ with IP Address 192.168.20.1.

Now there is an Oracle application which is sending SMTP email to outside through Domino Server. The Oracle developer is sending email to outside from his PC to his internal Application server and from internal application server to DMZ Domino server. After upgraded to r8.5 the only change is, they have removed all the IP entries from “Exclude these connecting hosts from Anti-relay checks” and placed the entry [192.168.20.*] (as I have mentioned they have bind the request coming from LAN Servers to one IP 192.168.20.2). now there are two issues;

  1. The application is not sending email to outside from the local domain giving the error (javax.mail.SendFailedException: 550 Relaying denied). According to the developer, the problem is only that the application is not sending email to outside, he can send email from application to any LAN user.

  2. Secondly, the email is not going to YAHOO.COM from all the users. They can send and receive to any internet domain like gmail, hotmail, anb, ogersystems,yahoo.co.uk but not to yahoo.com. they can receive from yahoo.com but cannot send. The email sent to yahoo.com is in the queue for a long time and then bouncing back to the user with sent expired notification. I have checked all the SMTP setting but did not find anything.

Appreciate if anyone share with me his experience to resolve the issues.

#1. In your server’s Configuration document > Router/SMTP > Restrictions & Controls > SMTP Inbound Controls > Inbound Relay Enforcement, I believe you will have to (a) disable all relay enforcement, or (b) exclude relay enforcement for the IP address of the computer that is trying to send messages through Domino.

#2. Does your mail log show entries for the messages it cannot transfer to yahoo.com?

Thanks a lot for reply. Actually all the messages sent to yahoo.com are remaining in Domino Queue for a long time and after that it is delivering the failure notice to the user with time expired. In the console the message is appearing “No messages transferred to YAHOO.COM. The remote server is not responding”.

I have tried to send the massage to yahoo.com from another company account and it sent successfully.

Subject: message not delivering to yahoo.com

This is correct error log in log.nsf

No messages transferred to YAHOO.COM (host d.mx.mail.YAHOO.COM) via SMTP: Remote system no longer responding

Subject: Yahoo.com

Yahoo can be tough. I’ve had trouble with them before and had to pursue it directly with Yahoo to make sure my client’s messages were getting through.

Subject: Solved

My both the issues are resolved.

First issue was due to MacAfee Anti-SPAM Gateway. The email was not even reaching to Domino server and was blocking by the gateway.

The second issue (yahoo mail) was not also a Domino Issue but was from ISP. once they revised some settings, the mail delivered to yahoo.com successfully.

Thanks
