Features in depth

This page covers the advanced features of Mail Portal

Mail Portal is your one-stop mail administration, webmail, contacts and calendaring gateway. Before following this in-depth guide, please make sure you’ve covered this help article.

Editing account details

Your account details like password and recovery email (used for password resets) can be updated from My account page.

My account page

Two-factor authentication (2FA)

Two-factor authentication (2FA) can be enabled/disabled from My account page. Add an extra layer of security for your account with time-based one-time password (TOTP). For more information on how 2FA works, see section Software Tokens for 2FA at Authy.

Split domain routing (SDR)

Split domain routing (SDR) enables you to host mail for a single domain on multiple servers (or services, Mailcheap / third-party). When SDR is set up for a domain at server A (with MX pointed to server A), server A would receive mails for all users of that domain and deliver to mailboxes hosted on server A and then relay the rest to another destination server B where mails are then delivered to mailboxes hosted on server B.

To enable / disable SDR, go to Domains > Actions > SDR

Split domain routing

Antispam thresholds (per-domain)

It is possible to set custom antispam thresholds (scores at which mails would be rejected, deferred or sent to junk folder) for each domain that would override any global antispam thresholds.

To set / update / reset custom thresholds for your domain, go to Domains > Actions > Antispam thresholds

The default scores are as below:

  • Reject mail: 10
  • Add X-Spam header and send mail to junk folder: 4
  • Defer (greylist) mail: 3

The scores for each of your email messages can be seen by inspecting its headers. You may experiment by changing the above default values to suit your requirements, but as a rule of thumb the scores should be in order: defer < add header < reject

Per-domain antispam thresholds

Whitelist & blacklist senders (per-domain)

It is possible to whitelist or blacklist senders for each of your domain(s) and override any global whitelist / blacklist rules.

To set / update / reset custom whitelist & blacklist rules for your domain, go to Domains > Actions > Antispam WL / BL

Per-domain whitelist & blacklist


Whitelist and blacklist actions are performed against the MAIL FROM (envelope) domain and not the DATA From header domain (which is what mail client’s display).

Domain aliases

Domain aliases enable receiving mail for a domain at your existing domain and its mailboxes.

For example, with a domain alias for newdomain.tld pointing to mydomain.tld, emails sent to user@newdomain.tld would be redirected to user@mydomain.tld

To create a domain alias, go to Domain aliases > New domain alias and follow the on-screen prompts. Please note that domain aliases must also be verified using the same DNS TXT method used for verifying domains.

Create domain alias

Relay domains

Relay domains enable relaying (forwarding) all mails for a domain to another mail server.

To create a relay domain, go to Relay domains > New relay domain and follow the on-screen prompts. Please note that relay domains must also be verified using the same DNS TXT method used for verifying domains.

Create relay domain


Aliases are email addresses that redirect mail sent to it to its recipients, both local and remote. Any alias with remote recipient(s) may be considered as a forward.

To create an alias/forward, go to Aliases / forwards > New alias and follow the on-screen prompts.

Create alias

Sender addresses

Sender addresses enable your MailUsers (email accounts) to send email as another sender. A sender address can belong to one or more usernames (MailUsers).

To create a sender address, go to Sender addresses > New sender address and follow the on-screen prompts.

Create sender address

Import / export

It is possible to import / export accounts, aliases, sender addresses, domains, domain aliases and relay domains.

To import / export aforementioned items, go to Import / export and follow the on-screen prompts.

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

To set up automatic migration for a domain, go to Auto migration > Add domain and follow the on-screen prompts. For detailed information, see Migration help article.

Auto migration


If you have a dedicated server, please make sure to watch the load averages from Server > Usage metrics so as not to put undue load on the server which may cause service disruption and loss of data. Migrate users incrementally, when performing migration for a large userbase if you’re unsure the server can handle the load.
