[Dipak Bhoi]

Hello Guys,

Some times you can see an error Domain example.com has exceeded the max defers and failures per hour (5/5 (100)) allowed. Let see what are the Deferrals emails.

If you go WHM >> Home »Email » View Sent Summary then you can see a column as "Deferrals"

Deferrals emails are those emails which queued in the mail queue because of some certain limit set for each domain per hour can send mails.
Suppose the limit is set 100 emails per hour and the domain is trying to send more than 200 emails, then after count reached 100, all emails will queue to deliver later on such emails are called as Deferrals emails.
