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.
