Hello guys,
When going to send an email facing following error, Please advise.
QuoteDomain example.com has exceeded the max defers and failures per hour (5/5 (100)) allowed
This error occur due to cPanel regularly monitoring the emails sent through all email accounts on your domain, and if over the past hour more than 100 of the attempted deliveries have failed then it blocked the outbound delivery temporarily.
After investigating on it I found the following file is created on server on following directory:
Quoteroot]#/var/cpanel/email_send_limits/max_deferfail_yourdomain.com
OR
root]#/var/cpanel/email_send_limits/defer_cutoff
I have delete this file, restart the exim service. Wondering, Problem is fixed.
Quoteroot]#rm -f /var/cpanel/email_send_limits/max_deferfail_yourdomain.com
OR
#rm -f /var/cpanel/email_send_limits/defer_cutoff
If you facing same problem again and again then simply change the permision of /var/cpanel/email_send_limits/
Quote#chmod 444 /var/cpanel/email_send_limits/
This will prevent to create these file automatically into directory.
