{Disarmed} - Email campaign

[LGnord]

Hi,


I begin to use sugarCRM and I have a problem with email campaign. I would like to send a newsletter. I follow instructions and I send a test. But I had a surprise when I receive the mail.

The title was: {Disarmed} [Test]: newsletter n.1 - june 08


I found some documentation about the label 'disarmed'. But, how can I configure sugarCRM to avoid this situation?

Thanks for your help.

Hello LGnord,

I was unable to find any reference to "disarmed" in the source code or in documentation-- where'd you find this documentation? I can take a look.

Thanks!

Thank for your answer.

Let me copy a part of the following page: disarmed email

The tag {Disarmed} in the subject of an email means that the MailScanner anti-virus system has removed potentially dangerous content — in the same way that you’d say “She disarmed the bomb”.

MailScanner will automatically remove the following kinds of content from email:

* File attachments which are frequently used to distribute malicious software, such as Windows .exe files. For the complete list, see Anti-virus “dangerous email attachments”.

* Files with suspicious names, such as names with a lot of spaces, or those ending in a “double extension” like .doc.exe.

* Files which have exactly the same names as known viruses, such as happy99.exe.

* HTML tags which can be used for malicious purposes, such as Iframe tags.

* “Web bugs” — small images used to track when you open an email. These are often used by email newsletters.


I have seen in another thread (http://www.sugarcrm.com/forums/showthread.php?t=32717) that sugarCRM automatically add a tracker to check wether a campaign email was open.

I think that this tracker is dedected by the MailScanner and then the {Disarmed} tag appears.

Do you agree with me?
Is-it possible to remove this feature?
Many people send newsletters with sugarCRM. Have they the same problem? Why?

Alright, it looks like your particular e-mail scanning software adds the {Disarmed} tag, but this won't happen for most e-mail readers. I'm not sure whether you can remove the tracker image from Sugar (you should consult the user documentation here: http://www.sugarcrm.com/crm/user_documentation), but you probably can by customizing the code. This will, however, prevent you from tracking whether any users viewed the e-mail.

My system administrator set our mailscanner to not disarm any emails.

Everything looks to be OK.

We are going to make more tests to be sure that their is no problem in our customer's mailbox.

Thank for your help.

There are at leased 2 reasons a mail scanner DISARMS your mail

1. many mail scanners can detect the image sugar is added to your mail as a tracer image (1x1spacer.gif).

2. they see you have added urls other then your own domain.

The scanner will remove the link and adds the {DISARMED} tag in the subject.

Solution to 1.

Sugar adds a image in the mail in the following php file: EmailMan.php

Changing the size of this image to eg. 10x12, will add an image in an other size. This will prefend the message tag {DISARMED} and the tracer will be working as well again.

Tested this and is passes 3 diferent kind of mail scanners. So it looks a good solution.

Sollution to 2.

Always point to your own site.
Add a page on your site where you pass the reader to the original source.

I have done this for an Oxfam campaign. The result is this:

Good luck

Hi all.

I'm having the same problem here.

Have created several email templates for Press Releases, but am not getting any joy with the [Disarmed] message.

I understand that we need to alter the size of the tracker image, but looking at emailman.php, I cannot see tha pixel path.

What I want to do is change the size of the tracker pixel to bypass this problem.

Pulling my hair out on this one, and we're days behind.

Any help?

Thanks

Allen,

The size is one of the possible reasons.

To change it:

search for: <IMG

in the EmailMan.php

and see this line:

<IMG HEIGHT='1' WIDTH='1' src='{$this->tracking_url}index.php?entryPoint=image&identifie r={$this->target_tracker_key}'>";

In my version it is on line 707

Change HEIGHT and WIDTH to other values.

In your mail source (right click in the email content) you can find the reason why the label {DISARMED} is placed.
There you find if the picture size is the problem.

Good Luck.

I had the same issues and have modified the line suggested by Eelco with random image dimensions, larger than 1px as 1x1 caused the problems, smaller than 8 to avoid the image to become too large. As no severe security restrictions apply, I think the rand() will just do here

$img_h = rand(2, 7);
$img_w = rand(2, 7);
$mail->Body .= "<br><IMG HEIGHT='" . $img_h . "' WIDTH='" . $img_w . "' src='{$this->tracking_url}index.php?entryPoint=image&identifier={$this->target_tracker_key}'>";

Hope this helps.
