    Is this related to email that the server is sending or receiving?

    What do the mail logs say?

    Is there a process that is timing out such as anti-virus or spam filtering that's taking so long to complete that remote mail servers timeout and resend even though you might have eventually delivered the original message?

    Less likely, any recent network changes that might be affecting tcp/ip, or general network issues near the server? Have you checked for a bad network & packet loss?

    Check your qmail send logs.

    What do the logs say regarding the outgoing emails to the recipient getting the duplicates?

    Are there any errors related to that recipients mail server?

    Are ALL emails being duplicated for all recipients?

    Are they regular emails? Do they have large attachments?
