Email Hosting

Operate your own email server? Consider SmartComputers backup mail service. When a mail server goes down and someone tries to send you an email, the message will be bounced back to the user. You won't lose any valuable emails with our mail backup services that can be setup regardless whether the domain is hosted by us or not. If the domain is not using our name servers, you will need to add our backup MX server's addresess as the backup MX records for your domain.

Background
When an email client tries to send emails, it lookup the domain's DNS to know what are the mail exchangers (MX) for the domain. Each MX record is given a preference number and the lowest becomes the primary mail server. Mail delivery is first attempted on the lowest preference number MX. If the delivery fails, it tries the second lowest preference MX and so on. If no mail servers can be reached then the mail will be bounced back to the sender.

Backup MX
SmartComputers mail backup service acts as your second, third and fourth priority mail servers. If your mail server cannot be reached, the mail will be routed to our mail backup servers and wait in queues. Our server will keep checking your mail server every 30 minutes. Once your mail server is detected available, our mail server will forward the emails to your mail server. Our mail server will keep attempting to deliver mail to your server for 14 days. Mails queued in our mail server exceeding 14 days will be returned to the sender. You also have the option to subscribe to our SmartFish anti-spam service, checking on your emails. Emails found to be Spam will be quarantined before reaching your email server. A web interface is provided to check quarantined emails as well as a daily quarantine reprt being email to you.
