I use vpopmail on qmail.
I have many customer domains on that mail server.
One of these customer domains tells me that, they rarely receive the
same mail a few times. That problem becomes nearly once a week for
this customer.
I haven't any complain from my other customers.
They use outlook or o.express for their mails.
What may the problem be ?
Do I have to change my configuration ?
This can be caused by the load on your server. Sometimes a long scan
time will cause the sending server to time out before the scan is
complete and your server acknowledges receipt. The sending server then
obligingly resends. Check the smtp logs for the corresponding duplicate
email. You'll see 2 receipts for it if this is what's happening.
Oh, and if this is the problem, I would install spamdyke to lighten the
load on your server. It works great. You'll be scanning a lot less
email, and filtering more spam at the same time. http://spamdyke.org/.
Personally, I'd install spamdyke in any case. You'll be glad you did.
