Hi

I have emails from some domains stripping the html content and only showing text.

I went and looked at MailScanner.conf and the setting "Convert HTML To Text = no" is currently set.

Which other line could be causing html content to be removed and replaced with text?

Thank you
Edward

Anyone with feedback?

Not enough information given to understand your problem. Can you be explicit in what exactly is happening?

My customer receives html emails from various places however the entire body of the email has all the images removed and you only have url's to the images and text.

Here is an example of an email:

mydomain: Dahua Switch SWDA105, 4-Port PoE Switch Unmanaged

mydomain: Dahua Switch SWDA105, Why not switch? 4-Port PoE Switch

Describe the mail flow for me.

How does mail get into the system? How many servers/devices/ does the mail go through before it hits your customers mailbox?

As far as I know, EFA/Mailscanner* do not strip out images from some emails. Is there something else doing before the mail gets to EFA?

* Actually, Mailscanner has lots of options, so I might have overlooked something.

before mail would come from the internet to exchange and the emails were received without an issue.

eFA is now in front of exchange and only since the change does it do this to the emails with html content.

Posted: **25 Mar 2022 19:04**

Hmmm... I've never heard of that before, so unless Exchange is doing something new, it must be EFA.

Let me dig through the /etc/MailScanner/MailScanner.conf and see if anything jumps out at me.

Posted: **25 Mar 2022 19:06**

Thank you, I tested it earlier by changing mx records to Exchange directly and the mails are coming through fine. When i put eFa back, i get the emails as per my example.

It might be something small that needs to be changed I am guessing?

sending you a pm.

Posted: **25 Mar 2022 19:22**

What are the settings of the following in your mailscanner.conf?

Spam Actions =
High Scoring Spam Actions =
Non Spam Actions =

Posted: **25 Mar 2022 19:33**

Here are the settings in the mailscanner.conf file:

Spam Actions = store
High Scoring Spam Actions = store
Non Spam Actions = deliver header "X-Spam-Status:No"

Posted: **25 Mar 2022 19:37**

can you send me your full mailscanner.conf configuration file?

otherwise, I have no idea.

Posted: **25 Mar 2022 20:45**

yes sure, will send it in the morning

Hi there

From a previous post I found viewtopic.php?t=1462) I changed the options below from disarm to yes. I did 1 at a time until all the emails were shown correctly.

Allow IFrame Tags = disarm
Allow Form Tags = disarm
Allow Script Tags = disarm
Allow WebBugs = disarm
Allow Object Codebase Tags = disarm

Posted: **29 Mar 2022 07:54**

Can you check the settings of these two parameters in your installation?

Convert Dangerous HTML To Text =
Convert HTML To Text =

My settings for the above two are "no", while the other Allow* parameters are set to disarm. I think that is why my html mail goes through untouched.

I'm not sure what the default setting is. If it's not the default, then I've changed it years ago and forgot I did it.

[edit: the default installation settings are "no"]
