selective IFRAME filtering

Hi Gary,

You can set up a ruleset for this.  Look for this line in your
MailScanner.conf file:

Allow IFrame Tags =

and point it to a ruleset filename.  For example:

Allow IFrame Tags  = /etc/MailScanner/rules/iframe.whitelist.rules

Then in your /etc/MailScanner/rules directory, create a file called

In it you can put entries like:

From:            someone at    yes
FromOrTo:    default                                no

I believe you can also put wildcards:

From:    *    yes

Just be sure that the last line of your ruleset file is

FromOrTo:        default    no

So that the default action for the rest of your mail will still be to
disallow IFrame tags.

is there a way to add this to a whitelist or something since I know it is
benign (I'd like to catch all other IFRAME tags though).
