Webmail specifications

This article provides an overview of different email specifications. 


Email and mailbox size

Mailbox storage sizes for our email service ranges from 5-15 GB, depending on your choice of email subscription in RAI. An email message can maximum be 35MB. Storage space and attachments are shared between mail messages, as well as the file storage feature of the webmail.


Spam and virus protection

Email filtering is automatically enabled on all inbound and outbound email messages. This ensures that infrastructure and users are protected against threats like spam and viruses.


Languages supported

The Webmail is available in 13 languages including English, French, Spanish, German and Brazilian Portuguese.


Email sending limits

The email service is not a mass emailing service - if possible, it's recommended that you include less than 10 recipients per message. The limit of the SMTP (simple mail transfer protocol) is 500 emails within a 24-hour period. If you reach your limit, an error message will appear: "Daily maximum exceeded". 

  Comparison with other email providers

  • Hotmail: 100 emails/recipients per day
  • Gmail: 500 emails/recipients per day
  • Yahoo: 100 emails/recipients per hour


Backup of emails and accounts

Emails can be restored within 14 days.

Email accounts can be restored within 30 days. The fee for restoring an email account is the same as restoring a website. Please contact the Mono Service Team if you want to restore an email account. 


Catch-all and email aliases 

Catch all mail is not possible with the webmail service. Instead of using catch-all it's possible to create unlimited email aliases.

  What is catch-all?

Catch all, in the context of email, refers to a mailbox on a domain that will catch all emails that is addressed to the domain but with an incorrect email recipient name. 


Blacklisting (user email bounce back)

An email blacklist is a real-time database that determines if an IP is sending an email that could be considered spam. If a customer gets a bounced email, the email may be blacklisted.

Create a ticket with the Mono Service Team with the original email if you're having problems with email bounce backs. Click here to check if an email is blacklisted.


Whitelist an email

Spam filters have whitelists and blacklists of senders and keywords to look for in emails. Email addresses, domains and IPs that are whitelisted will always be allowed to be received by the webmail. Click here if you want to whitelist an email account on different email clients.


AUP suspensions (if a user can't send emails)

Email users can get suspended from sending emails if they are reported by outsiders for sending spam. The customer must check the computer for malware/virus and change webmail password before Mono can lift the suspension.

IMAP (Internet Message Access Protocol) allows you to store your email on remote servers. This two-way protocol also allows you to synchronize your email across multiple devices.

POP (Post Office Protocol) downloads your emails to your computer and usually (but not always) deletes the email from the remote server. This might pose an issue if you use more than one device to read your emails (desktop, laptop, tablet or phone).
