Dear All,
Complaint from our users. Any ideas on getting 2 same emails occasionally ? I have double check with sender. They have sent once only. We use clustering. Any setting that we may miss ? Any other reasons for getting 2 same emails ? One of our cases get 4 same emails ! But just once. Interesting that some users hasn’t faced this problems.
THanks for your help.
Subject: Help: Occasionally get duplicate emails
Are you having any other trouble with inbound SMTP - instability, connectivity, DNS issues etc? This has happened to me on occasion and it’s always when I’m having massive trouble with my SMTP servers. I’m configured with 2 smtp servers in 2 locations with 2 mx records and A records… When (God forbid) I’m having trouble with both servers for whatever reason (ISP issue, DNS issue, firewall issue etc), I get some duplicate messages during that period. I don’t have a fix, it “goes away” shortly after we get SMTP services stablized. I chaulk it up to the sender’s smtp server who continues to try to deliver the message and doesn’t realize the message got through because the server went down prior to successfully accepting the message. I’m no smtp expert but it’s not a chronic issue so I don’t dig much deeper. Hope this helps.
