Configuring Account Class Quotas & Restrictions

Axigen Documentation

The "Account Classes" → "Quotas and Restrictions" page contains parameters relative to mailbox and folder level, notifications to be sent to users and restrictions imposed for all created account classes.

Changing the parameters below will affect the accounts that have inherited parameters. Explicitly set parameters will not be affected.

Managing Account Quotas

At mailbox level, the total mailbox size, the total number of folders and the total number of messages can be limited by selecting the respective options in the "Mailbox" area and using the up and down arrows to adjust the limits to the desired value. For the total size limit, use the available drop-down menu to select if you want it calculated in KB, MB, or GB. 

In addition, you can have older messages in the Trash and / or Spam folders automatically purged, based on an age criteria. By default, this option is enabled to purge messages older than 1 month.

Set limits for the size of each folder and the total number of messages per each folder by checking the respective options in the "Folders" section and using the up and down arrows to adjust the limits to the desired value. For the folder size limit, use the available drop-down menu to select if you want it calculated in KB, MB, or GB. The maximum possible value for "total size limit" is 1 KB lower than 4096 GB. 

To notify the account user (through a pop-up displayed when accessing the WebMail interface) when a certain level of the allowed quota is reached, check the respective option in the 'Notifications' area and edit the default percentage. You can also choose to have the user notified at every login via an email and control the frequency of these login notifications. The frequency of these login notifications can be set using the up and down arrows corresponding to this additional option. To select if the respective value is calculated in minutes, hours or days use the respective drop-down menu.

You can further edit the notification content in the "Notification email content" section. This section will only be displayed after checking the box related to the "Also send a notification email each time the user logs in but no more frequently than every..." option. The "Quota limit notification file name" section will contains the eml file that will be sent when the quota limit is reached.

Another option is to restrict the user from sending any new emails when he reaches a specific used quota percentage. By default this is set to 0%, so the user will be able to send emails until he reaches his quota. The percentage you set for this option must be higher than the quota usage warning percentage.

Contact Information

In this section you can disallow the user from changing it's personal contact information, restricting access to the corresponding contact details.

Password Policy Enforcement

You can define a Password Policy to be enforced for the currently created account. First of all, a minimum and maximum number of characters for each password can be set using the up and down arrows or directly editing the "Password length parameters" text field. Further select from the Password must include dropdown menu if passwords should include letters, letters and numbers or letters, numbers and special characters. You can also set specific password changing options like the number of previous passwords that should not be accepted as the new password, a minimum period between two password changes and if the user is allowed to change the password.

Password Expiration

In this section you can enable, by checking the related box, the "Enable password expiration" option and then customize the password expiration and related notifications in compliance with your requirements.

2-Step Verification

Starting with Axigen X3, 2-Step Verification (Two Factor Authentication) is available for WebMail. 

Axigen implements 2-Step Verification by using the TOTP algorithm (compatible TOTP mobile apps: Google Authenticator, Microsoft Authenticator, etc.).

Account Recovery

You can allow your end-users to recover their username and / or reset their forgotten password by using the following methods:

  • Secret Question — allows users to define a secret question — either from a predefined set of questions or by writing their own question — and set the answer to it. When they lose access to their account, they can recover it by answering the secret question. This can be done in their WebMail settings from GeneralCredential recovery.

  • Personal Email Address (PEA) — allows users to define a Personal Email Address that will be used in case they lose access to their account. This address can be added in their WebMail settings, by going to GeneralAccount InfoMore and by filling in the “Personal Email Address” field.

  • Both Secret Question and Personal Email Address (PEA)

From this section, you can decide which methods you allow your end-users to make use of, as well as set the path on the disk to the email templates that are used for the automated emails sent within the recovery process.

Session Restrictions

The number of POP3, IMAP and WebMail sessions can be limited for the respective account. To do so select the desired value, use the up and down arrows or directly edit the text fields pertaining to each type of session.

In the WebMail advertising area you can configure the two advertising sections of the interface (only pertaining to the Ajax WebMail interface) by inserting appropriate HTML code in the corresponding parts. We recommend respecting the maximum size specified for each section.

To limit the size of email message attachments, check the respective option in the WebMail section and use the up and down arrow to select the desired size. To have the size measured in KB, MB or GB use the available drop-down menu.

Use the up and down arrows of the "Limit number of attachments per message" option or edit its corresponding text field to set a maximum number of attachments allowed to email messages sent or received using the WebMail interface

Check the "Limit message size" option to set a maximum size for sent and received messages through the WebMail interface. To do so either use the up and down arrows to select the desired size or edit the corresponding text field.

The "Limit number of recipients" option allows you to configure a maximum number of recipients for WebMail email messages using the up and down arrows to select the desired size or editing the corresponding text field.

To set the "HTML Body Filtering Level" for this specific account when connected via WebMail use the available slider. The HTML filtering levels stand for the following:

  • No Filtering;

  • Low level filtering – converts the message to standard XHTML;

  • Medium level filtering – generates the email body based on a list of known/allowed attributes and tags. Anything that is not on this "allowed list" is removed. This level removes java script, styles, etc.;

  • High level filtering – generates the email body based only on text components. This means that only plain text components remain in the message. This forth level is the strictest and may actually damage some formatting, but it is also the safest.

A minimum email body filtering restriction can be applied by dragging the "Minimum allowed HTML Body Filtering Level" slider to the desired setting. This will not allow the user to set the email body filtering level (from WebMail) to a lower value than the one specified in WebAdmin.

The permission to use Calendar availability sharing for users in this domain can be disabled or enabled from this section, by checking/un-checking the related boxes.

Remote POP Restrictions

You can limit the number of remote POP accounts defined by a certain user. To do so, use the up and down arrows to select the desired size or edit the corresponding text field. Additionally, a minimum interval between two email retrievals for each RPOP connection can be specified. Use the "Minimum message retrieval interval" drop-down menu to have it calculated in seconds, minutes or hours.

Temporary Email Addresses Restrictions

You can set some limits regarding the usage of temporary email addresses. A user may request maximum 16 temporary email addresses (aliases), if the limit is set to "0" the "Add" button in WebMail (in the "Temporary Email Addresses" section) will be disabled but old temporary email address will still be available until they expire or are deleted. The time period from the creation of a temporary email address to its automatic deletion can be set between 10 minutes and 1 year.

Parameter inheritance: the parameters or parameter groups that are inherited from the domain's account defaults are automatically marked with the "Inherited from domain's account defaults" icon, while the ones inherited from an account class are marked with the "Inherited from account class" icon. When explicitly setting the value of an inherited parameter, it will be marked with the Set explicitly icon. Moreover, any further changes at parent level (domain's account defaults or account class) will only affect inherited parameters, while explicitly set ones will keep their value. You can revert the explicit parameters to their inherited value at any time by clicking the "Inherit" link related to the explicitly set parameter (orange) icon.


Once your changes are complete, save them by clicking the "Save configuration" button.
