Introducing the New Mail System (NMS)

The New Mail System (NMS) is an API first hosted email platform from Mailcheap. It enables you to control every facet of an email system using the API, even the GUI is entirely built on top of it.

In addition to supporting SMTP, IMAP & POP protocols for sending/fetching emails, it also has native contacts (CardDAV) & calendaring (shareable, CalDAV) support, two-factor authentication (2FA) and an automatic migration feature (more on that below).

In essence, NMS allows complete programmatic access to email administration (via HTTPS API) and usage (through existing SMTP/IMAP/POP protocols), thereby providing seamless integration with your existing systems.

System features

  • 100% API support for email administration
  • Responsive, modern HTML5 frontend (GUI)
  • Blazing fast (after the first few page loads!) GUI built entirely in client-side Javascript
  • Multiple permission levels including MasterAdmin (dedicated servers), DomainAdmin (shared servers, provisioned during/after beta) and MailUser – more on that below
  • Automatic migration feature – more on that below
  • TOTP based two-factor authentication (2FA)
  • IMAP / POP / SMTP support
  • Complete control over your data with dedicated server: ability to backup calendaring/contacts data and email data.

Mail features

  • Domains with SDR, DKIM, antispam thresholds and antispam whitelist/blacklist controls
  • Mailboxes
  • Aliases & forwards
  • Sender addresses
  • Domain aliases
  • Relay domains with antispam thresholds and antispam whitelist/blacklist controls
  • Import / export above items
  • Contacts (CardDAV)
  • Calendar (shareable, CalDAV)
  • Server-side message filters based on sieve
  • Server-side vacation autoreply based on sieve


  • Roundcube: default and recommended webmail with contacts (CardDAV) and calendar (CalDAV) support
  • Rainloop: alternate webmail

Permission levels

  • MailUser is the permission level with ability to send and receive emails.
  • DomainAdmin administers all MailUsers of domains belonging to them.
  • MasterAdmin administers all admins & MailUsers and has access to server-wide configuration.

Auto migration

Auto migration enables you to migrate users and their emails without resetting passwords, importing them into the system manually or performing email data migration for each user

How it works

  • Set up auto migration for a domain with your existing (source) IMAP server details
  • Your users can then sign up from the login page
  • The system checks their credentials with the source IMAP server, creates an account for them and migrates the emails
