This is a snippet from MailScanner.conf

Allow IFrame Tags = /etc/MailScanner/rules/iframe.tags.rules
Log IFrame Tags = yes
Allow Form Tags =/etc/MailScanner/rules/form.tags.rules
Allow Object Codebase Tags = /etc/MailScanner/rules/codebase.tags.rules
Convert Dangerous HTML To Text = yes
Convert HTML To Text = no

/etc/MailScanner/rules/iframe.tags.rules contains:
From:      *         yes
From:      *    yes
FromTo:      default            no

so according to the comments we should be hitting the last option below
for messages from
# Allow...Tags    Convert Danger...    Action Taken on HTML Message
# ============    =================    ============================
#    no              no                Blocked
#    no              yes               Blocked
#    disarm          no                Specified HTML tags disarmed
#    disarm          yes               Specified HTML tags disarmed
#    yes             no                Nothing, allowed to pass
*#    yes             yes               All HTML tags stripped**

But our users are still getting Blocked content reports on email from containing I-Frame tags.


At Thu Dec  4 08:32:22 2003 the content filters said:
   MailScanner: Found dangerous IFrame tag in HTML message

This worked previously on 4-22 (upgraded to 4-25-14 yesterday)
Anyone have any idea's where I'm going wrong?
