I recently implemented an outsourced Anti-spam and Virus Protection Service for our companies. It works very well for us, but as with any such service, some spam is bound to slip through. In order to prevent repeat spam, the service provider likes us to send the complete headers of the original e-mail so they can analyze it and deal with it.
As you may know, this is rather easy in most e-mail systems, but it's impossible to accomplish in Lotus Notes R5 in a user-friendly way -- it's very tedious and time-consuming to say the least.
To make my life easier I developed an Action Button to capture all of the headers of an R5 e-mail. I was especially concerned with the "Received" headers -- there can be many of them in a single e-mail. Accessing and working with the Received headers using LotusScript required a rather unorthodox approach.
I placed this Action Button code in the Mail (R5.0) template's ($Inbox) folder with a title of "Get Headers" and let it propagate overnight. Now, when a user calls saying spam got through, I simply have them select the message in their Inbox and click the Get Headers button. They can have it display on the screen or create a text file or both. I usually have them just display it on the screen and if I determine it really is spam, I have them create the file and send it to the service provider. Done. Finished. That's all there is to it!

Is there an easier way to do this in R6? I have servers running on AIX that we need to report the SMTP headers to a SPAM service. I've tried script, but have not solved how to get all the RouterServers fields -- it only reports the first one.
Here is my agent behind a button to notify a group about the spam, but I need advice to get all the SMTP headers to show the spoofing.

GetFormattedText( False, 0 )) Call rtitem.AddNewLine( 2 ) Call email1.Send(False) Set doc = collection.GetNextDocument(doc) Wend Exit Sub NoDocs: Messagebox "You did not select any spam messages to report. Exiting", 0, "NoSpamSelected" End Sub
I believe the key to your solution is in the following code snippet from my original tip:
REM Special case for the "Received" headers FieldName = "Received" SpecificHeader = "" While doc.HasItem( FieldName ) Set item = doc.GetFirstItem( FieldName ) SpecificHeader = SpecificHeader & Fieldname & ": " & item.Text & CRLF Call item.Remove ' It's okay -- we won't save the document so these will NOT be lost Wend
You can set the FieldName variable to retrieve those headers you are having problems with. "Normal" methods will NOT retrieve the headers having multiple fields (NotesItems) with the same name. The code above WILL get them -- REMOVING the items as you "loop" through them is the only way. This works very well, as long as you:
A) Don't need to do a Save on the original document.
B) Don't care if you lose the headers if you DO save the original document.
It sounds a lot harder/trickier than it really is!

This is great tip. But how can I get content-type data from the header? There is no such data you can see when selecting View->Show->Page Source.
I believe the content-type headers are always contained in the Body field(s) of a Notes memo. Some, especially from Web TV, are extracted by the code I posted, even though they ARE contained in one of the Body fields. Refer to this screenshot of a file created by the code I posted in the original tip -- I've highlighted the content-type in yellow.
Try using the NotesMIMEEntity class in LotusScript to DIRECTLY access the MIME Content-related properties of a memo -- refer to Designer Help and search for MIME. It should be pretty simple.
