Adding Warning Message to email body

icoso
This has become a major issue for my customers for compliance that they have a note added to their incoming messages that Warns them of external incoming messages. This is something that is forcing many users to move to an exchange service because this is easily implemented in Exchange/Outlook environments. Is there a way to add a Warning Message to all incoming emails that do not match the current domain? For example, My domain that is configured in CPanel is mymaildomain.org. For every incoming email message to our domain that passes through all previous checks, and SPAM Assassin checks, that does not contain mymaildomain.org, I'd like to add the text to the top of the message body that states "WARNING: EXTERNAL EMAIL. Do NOT CLICK on links or open attachments unless you are expecting it or have verified with the sender." Or whatever I want it to say. It seems like this would be pretty easy to implement within the CPanel Global Email Filters. If another option was added to the actions, ie: " Add Note to Body" then have a text box to define the "Text" of the message. This would solve this issue. All of the current rules already apply, such as the Rule for From - Does Not Contain - then we could specify the domain or any text, the Action would then be to "Add Note to Body". Or another way to do this would be to Rewrite the subject with a short text: "EXTERNAL: " (Much like SPAM Assassin does with suspected SPAM) then we could use the existing the Rules to add a test for that same word, so it doesn't keep rewriting the subject if it contains that same word. To do this, we'd need an Action of "Rewrite Subject". Another way to do this would be to use the Pipe to Program function, However I can't find any script out there that would do either of what Im suggesting. Any help, suggestions, direction, assistance, with this matter would be greatly appreciated. If anyone can write a script that would do this I'd be very much appreciative.

    Hello, You can definitely rewrite the headers in the same way that Spam Assassin does to append ***SPAM*** to them. I believe you could also add a notice to the body of the message. The thread here might be helpful for this: I'd recommend using the Exim System Filter to make these modifications which would do so globally

    You'd want to use headers_add to do this. There are quite a few threads on the forums that go over headers add and headers remove:

    This issue has become so widespread with all of my customers due to compliance and Fed regulations, that Im losing customers because CPanel email services cant add this to the subject or the beginning of the body. I need to know HOW to ADD to the beginning of the subject for EVERY incoming message that is NOT from the local domain, to something like this: "WARNING - EXTERNAL MESSAGE" UNLESS the subject already contains the word "EXTERNAL". As in most cases I use a VPS from a hosting vendor, in which I have access to edit the exim config files, for my VPS using my WHM for all my domain accounts. I've read all those posts listed above and they aren't quite specific enough for me to do this, some change the from address, some change the subject and then redirect, but they don't address this issue specifically. Here is my case: 1 I have a VPS with multiple domains on it. ie: customeronedomain.com, custtwodomain.com, customerthree.com etc... 2. Someone from anyone@anyplace.com domain sends an email to john@customeronedomain.com, OR jane@customerthree.com, OR the recipient is part of a CC or BCC list, (notice the sending domain is not the same as the recipients domain). 3. If the sending domain is not the same as the recipients domain, then the subject needs to be changed to include "WARNING - EXTERNAL MESSAGE" at the beginning of the subject, UNLESS the word "EXTERNAL" is already in the subject. 4. continue delivery normally to the recipients. This should be really easy and would be GREAT if CPANEL would simply make this a checkable option under the email addresses page in the CPanel or even on the Exim Config page in the WHM.

    Is there anyone out there that can help with this issue?   It would seemingly be fairly easy to implement from the back end by using the Global or Account Email Filters in Cpanel.   On a Filter  it would be easy to set the Rule FROM to the current domain name: ie: mydomainname.org and the next field to Does Not Contain enter the current domain name in the text field and then the have a NEW ACTION that would be: Change Subject  then have an entry field that would allow you to add text and use a variable of some type to keep the current subject, ie: the input would be like  [WARNING: EXTERNAL EMAIL] %subject%

    This entry would add the wording [WARNING: EXTERNAL EMAIL]  and keep the current subject of the message.   Having a feature like this added to the Filter actions  would solve so many issues for those of us having to abide some Federal Regulations.   MS Exchange/Outlook services is doing this now and has been fro a few years. 

    I suppose I could set the action to pipe to a program but I have no idea, how/where a program would exist.  If anyone has EVER done this action what kind of program is it looking for and how can I simply change the Subject of an incoming email message?

    I submitted the idea for this feature. 

    Adding Warning Message to emails comming from external domains.

    We would like to offer customers the option to add a warning to all emails originating from an external domain through their cPanel. Ideally, this warning should be customizable. For example, "ALERT: This message is from an EXTERNAL sender – be especially careful with links and attachments. If you are suspicious, report it immediately by forwarding it to phishing@domain.com."

    We would like to offer clients the option to activate a warning from their cPanel to add a warning to all emails originating from an external domain. Ideally, this warning should be customizable. For example, "ALERT: This message is from an EXTERNAL sender – be especially careful with links and attachments. If you are suspicious, report it immediately by forwarding it to phishing@domain.com."

    Several clients have asked me for this in recent months.

    Thanks

    Hi Rex, thanks a lot!

    Another suggestion: features.cpanel.net needs a newsletter so we know when something new is being considered or if something has been released.

    I'm working with the team now to see if we can get something added to the existing newsletter.  We don't want to have a whole separate publication just for this.

    I will say, our team *just* released a post to social media about the features site about 2 hours ago, if you follow us on any platforms.
