I am using MailScanner 4.39 on RH9. I have a user that when they receive an email from a certain place it converts the mail to a text file and puts it as an attachment in the email. The From email address is in the whitelist. But in the header of the email it says this:

X-MailScanner-From: emailsubscription@journaltogo.com
Content-Type: text/plain; charset=unknown-8bit
Content-Transfer-Encoding: quoted-printable
X-MIME-Autoconverted: from 8bit to quoted-printable by mail.someplace.com id j6A7e0ri017362

** mail.someplace.com is my email server with MailScanner

This is telling me that MailScanner or the MTA is converting the email to a text file. Any help on this matter would be greatly appreciated.

Look in MailScanner.conf for the following:

# This option interacts with the "Allow ... Tags" options above like this:
#
# 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
#
# If an "Allow ... Tags = yes" is triggered by a message, and this
# "Convert Dangerous HTML To Text" is set to "yes", then the HTML
# message will be converted to plain text. This makes the HTML
# harmless, while still allowing your users to see the text content
# of the messages. Note that all graphical content will be removed.
#
# This can also be the filename of a ruleset, so you can make this apply
# only to specific users or domains.
Convert Dangerous HTML To Text = no

# Do you want to convert all HTML messages into plain text?
# This is very useful for users who are children or are easily offended
# by nasty things like pornographic spam.
# This can also be the filename of a ruleset, so you can switch this
# feature on and off for particular users or domains.
Convert HTML To Text = no

I bet one of these is involved, along with the attachment settings for what to do with cleaned messages.

I looked at my MailScanner.conf and this is what the following entry's are set to:

Convert Dangerous HTML To Text = no
Convert HTML To Text = no

I also looked for the cleaned attachment setting and it is set to deliver cleaned messages. Any other suggestions would be greatly appreciated.
