Bypass Max hourly emails per domain

[KV Karia]

One of our cpanel password compromised and found that thousands of mails is in queue with SMTP Authentication as [email protected] id.

We have Max hourly emails per domain is 100 then how it bypassed?
and thousands of mail become in queue?

How to prevent such things in future? what steps to be taken?

SMTP Authentication as [email protected] id.

but from id is something different like [email protected] which xyz.com is not hosted on our server.

Dear Sir

Provided URL guidelines already followed.

Hi,

Are those mails send from your server and lined up in the undelivered mail queue only ?

Hello,

Can you provide an example of one of the messages as it appears in /var/log/exim_mainlog? EX:

exigrep MSGID /var/log/exim_mainlog

Replace "MSGID" with the message ID as found in the header of one of the messages, or replace it with the name of the email account used to send email.

Thank you.
