How CCS Leeds Exchange MX Backup Service Works:

When an email is sent to a recipient the email server looks to see which server handles mail for the domain using the DNS MX records. MX records specify which server(s) will receive mail for a given domain. Each MX record is given a priority (the MX level), the lowest being the primary mail server. The primary mail server is responsible for delivering the mail to the appropriate user mailbox.

Mail delivery is first attempted to be delivered to the primary mail server (the mail server indicated by the MX record with the lowest numbered MX level). If that server is not reachable then the mail will be attempted to be delivered to the mail server with the second lowest MX level. If the second lowest mail server in priority can not be reached then the mail will be delivered to the mail server with the third lowest mx level (third lowest priority) and so on.

If no mail servers can be reached then mail is sometimes queued but is usually just bounced back to the sender. This can lead to lost sales and lost revenue and worst of all lost of communication and respect.

Backup MX Mail Service:

CCS Leeds Backup MX Mail Services gives you access to three additional email servers for complete email redundancy. So if you will have an extra three levels of MX records giving your domain four levels (minimum, including your own servers) of MX priority.

If your mail server cannot be reached then your email is then sent to CCS Leeds backup mail servers. Once it reaches our servers it sits in a queue and continually checks to see if your mail server is back online and is reachable. When your mail server is back online the queued mail is then delivered to your mail server. CCS Leeds will keep attempting to deliver mail to your server for 14 days!

Quota and limitations:

New - Unlimited email volume stored

CCS imposes no quota or limit on the volume or number of emails that will be held in spool for you. We only request that we are not your primary email provider and that the service is used as a backup or secondary service. We believe it is key to the business continuity of your email service that we do not impose limits on the utilisation of the service as you will undoubtedly have more urgent matters to deal with in the event of use of our service, rather than worrying whether you might reach a service cap on your backup email provision.

Does CCS Leeds block any emails or is this a spammers open relay to my systems?:
