Steps to reproduce
------------------
Go to control panel -> Server Administration -> Mail
Edit advances preferences textarea
Save
Result: the advanced preferences are not displayed (however, the preferences are stored in the database)

Cause:
<aui:input cssClass="lfr-textarea-container" label="manually-specify-additional-javamail-properties-to-override-the-above-configuration" name='<%= "advancedProperties" + PrefsPropsUtil.getString(PropsKeys.MAIL_SESSION_MAIL_ADVANCED_PROPERTIES, StringPool.BLANK) %>' type="textarea" />

This input doesn't have defined the value field, and its name is wrong
