Claris E-Mailer
Under Mail, select Show Long Headers.
Lotus
Select the Message for which you want to analyze the header. Click File, Export, give a name to the export file, and then leave the file type as structured text. Now open the exported mail with Notepad. You will find the sender's server type (Exchange, sendmail, etc.), server IP or Domain Address routing path in the exported file. We also have On-line SMTP Header readers to find the information for us. Copy the entire text and paste it in the Analyzer to find out more information about the Sender's Domain.
Header Analyzer tool can be located at this url: http://tools.appriver.com/index.aspx?tool=header.
Lotus Notes 4.6 (Win 9x client)
Open the properties box on the message (in the default installation of the Notes Client, it will be the first smart icon on the left, but you can also right-click the document and choose properties from that menu). Choose the second tab on the properties box, which contains a list of fields and their contents. Scroll down to the field $additionalheaders. Select the contents of the field and click Ctrl C to copy them to your clipboard. Open a new e-mail message, put your cursor in the body of the message, and click Ctrl V to paste the headers. If Notes will not permit you to select the contents of the field, then you need to manually copy them to a new message. (Please be very careful with this procedure.)
Lotus Notes R5
Lotus Notes 5.x
Export the message as structured text to a file, then copy/paste the entire message. You should get all the received fields with Received: already in place. You'll also get reply-to: and other SMTP headers. Lotus Notes for v5.x - Single click the subject line without opening the document to full screen. Select File (upper left), select Export Name the file, select Export, click the selected documents, and then click OK. The file now exists where you have saved it. You can open it or attach the file to an e-mail. To open it, you need to select a word processing program (Wordpad is recommended) or you can attach the file to an e-mail without opening it yourself.
Lotus Notes 6.x
You might be able to get header information (of an open e-mail) by clicking View, Show, and then Page Source. This will show the entire contents of the message, with of course, the headers at the top of the message. Also, in Lotus Notes version 4x, 5x, you can click Edit/Properties. From here, click the 2nd tab, and you'll find quite a number of fields. Lotus Notes breaks up the various header entries into various received fields, which are individually selectable, and can be copied and pasted. A little cumbersome, but a method that I've had to use for troubleshooting in the past. Please note that some versions or installations of Lotus Notes do not comply with Internet standards and discard the headers. If that is the case, you should contact your system administrator to see if there are any logs of incoming mail that might assist you. You as the user will not be able to get the headers at all. Please see Notes.net for further information.
