I just found a curious thing that I want to have more information on. And eventually see how Imail handle things, to confirm it is an error, a bug, a problem or just a wrong configuration from my side.
A client wants to send email to a user at andinet.com It is an ISP with one MX record that points to 3 IPS IP=200.115.100.7 IP=200.115.102.11 IP=200.115.100.6 You can check http://www.dnsreport.com/tools/dnsreport.ch?domain=andinet.com the thing is that from time to time, or at least is what my tests show. The first IP doesn't respond to port 25. When Imail tries to connect to that IP (first in the list) it cannot. I run a telnet to that IP in port 25 telnet 200.11.100.7 25 and the connection failed. However the remaining IPs work perfectly in port 25 and respond OK. >From what I see in the logs it seems like Imail tries to connect to the first IP it sees in the MX record. If it fails, it doesn't try the second or the third IP on the MX list. Is that a standard Imail Behavior? To connect it uses the first IP reported on every MX record, and if the connection fails it goes to the next MX record, but doesn't even try to use other IPs in the same MX record found first? Could somebody clarify this? -Luis Arango ______ [Email scanned for viruses by Panda Consulting -www.pandacons.com-] [Email escaneado contra virus por Panda Consulting -www.pandacons.com-] To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
