enabled
Select this option to defang HTML in emails. Tags which are used to embed
active contents and form elements will be affected. The same applies to scripting
and unknown HTML elements. References to external resources which trigger
unnoticeable actions are filtered, too. The target of links will be removed if it refers
to active components.
all-out
In addition to the measures described for option "enabled", with this setting all
references and any link target will become unusable.
Remove redundant HTML parts
Some mail programs can be configured to send the contents of every email twice,
as plain text and in HTML. Both parts are denoted as alternative contents (multipart/
alternative). The recipient's mail client will choose according to its capabilities and
configuration which part it is going to display.
To automatically remove the HTML part of alternative contents you can enable this
switch.
Only inbound emails will be filtered. Pure HTML emails will not
be affected.
The removed HTML part will not be quarantined. There's no
way to restore it. No notification will be sent to the administrator
either.
Use this option to save bandwidth if e.g. mobile clients will be retrieving emails. In
addition local users will be protected from unwanted side effects of HTML mails without
the risk of loosing information, as one can expect identical text contents in both parts
