This article will cover what the Continuity Service is and how it works.


  • A MPmail Partner Account
  • A MPmail Customer with Continuity Service

The Process

The continuity service is a fully automated service, which initiates dynamically when our system observes that your destination mail server provides the MPMail servers with a temporary SMTP fault response code.

Temporary SMTP fault response can be provided by your mail server for a number of reasons. These reasons include the following:

  • ISP outage
  • Server overload
  • Mail database corruption
  • Firewall interference
  • Disaster Recovery

Once MPMail sees the temporary SMTP fault it will dynamically create a POP/IMAP mailbox for each of your registered users. It will direct all future incoming emails to the continuity portal, accessible here

Please note that if a user hasn't been activated in the panel they will not be able to access the Continuity mailbox. Any changes you make to the status will take 30 minutes to go through, password changes will take up to 5 minutes to sync as well. To set a user as active or change their password please do the following:

  • Go to Management tab
  • Select the Customer
  • Click on the User tab
  • Click on the User Settings tab
  • Set the password and make them active
  • Click Save
  • If you are using LDAP then please make sure all users have previously logged in as it will store their last used password in case your server is unreachable.

During this time you can also setup the IMAP/POP mailbox on your Outlook or Mobile device using the following settings:

IMAP4: Port 143 or 993 (SSL)

POP3: Port 110 or 995 (SSL)

SMTP: Port 25 or 587 (use SMTP authentication with your email address and MPMail portal password)

Please note that this is not a Full Exchange Mailbox so on Mobile devices please select IMAP/POP and not Exchange.
