Implementation: Backup email spooler implemented for shared hosting
Posted by Bill Williams on 26 February 2016 09:56 PM
We have implemented backup email spooler for Linux web hosting accounts, which will ensure 100% email delivery even if your primary email server experiences an outage.
How does this work?
The first step in the process of delivering mail is for the sending mail server to lookup what's called an MX record. This record provides the sending server with a list of servers that it should try to deliver mail to. These records also contain a priority or weight that tells the sending server in what order it should try delivery. The sending server then attempts to connect into each remote server and deliver the message, if the sending server cannot make a connection it will simply try the next server in it's list. The BackupMX server will be one of these servers in the list and when mail is delivered to it, the BackupMX will immediately try to deliver the message to the lowest MX server. If that delivery fails the BackupMX stores the email in it's spool and waits a set amount of time were it will attempt delivery again.
Hence we now expect all your email to be 100% secure, even if there is outage with your primary email server.
If you are using IndicHosts.net nameservers in the domain name settings, no further action is required as we will take care of everything for you. However for any reason if the nameservers in use are not of the IndicHosts network, please make a ticket with CustomerSupport department to know the steps you have to implement to get this operation on your domain.
This feature is free of cost for most web hosting plans.
