How to check the Mail Queue in WHM?

It is common problem among dedicated server, If they dont maintain the security of the website properly. If you dont take enough steps to protect the security of your server, then this kind of issues are very common in linux based vps or dedicated. If the server is hacked or malware injected, then the hacker could use your server to send millions of potentially spam mail using your server, To avoid this, you need to check the mail queue if you are having any mail delay or mail not sending problem.

Mail Queue is the latest method of sending and keeping a track of emails. Mail queue will be storing each email sent by you and it is also been recorded whether it is success or failure. You can queue up unsent mail and examine the mail generated by your WHM. If the receiving mail server returns there will be a temporary SMTP response code. Mails in the delayed queue are removed periodically until the timeout is reached. The action such as queued for delivery indicated that the mail is already in HES (Hosted Email Security) outbound MTA (Mail Transfer Agent) but for few purposes, will not be accepted by the receiving mail server because of the temporary error.

The mail tracking details represent the MTA (Mail Transfer Agent) level logs and give the data on what happens to an email when it is being delivered from one HES MTA server to a different server. The error messages displayed are straight away taken from the MTA logs. There will be no changes to the error messages and the SMTP response codes are modified by the service. HES Support Admin accounts will be displaying more elaborated mail tracking data which has been deployed to the HES production website. Mail tracking details will be available for both incoming and outgoing traffic.
