Adding a mailto: link from the E-mail tab of the Hyperlink Manager dialog in the Rich Text Editor (RTE) might result in the following validation error:
The Link field must have a Target value
The validation rule, applied by default, requires that all external links have a "target" attribute. Mailto: links are external links that should not require the "target" attribute.

To mitigate the issue, consider one of the following options:
- Disable the default validator by removing the "Extern Link Target" rule for the RTE field (/sitecore/system/Settings/Validation Rules/Field Types/Rich Text).
- Perform the steps below:
- Copy the attached Sitecore.Support.113263.dll file into the "/bin" folder of your solution.
- Navigate to the "/sitecore/system/Settings/Validation Rules/Field Rules/System/Extern Link Target" item in the Master database.
- Change the value of the "Type" field to the next one:
Sitecore.Support.Data.Validators.FieldValidators.ExternLinkTargetValidator,Sitecore.Support.113263
- Create a custom validator and use it instead of the default one.
