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.

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 the 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.
