[quote user="Correlator"]If you don't get such messages too often, save it into a file with extension *.b64 and then use, for example, WinZip to "open" it. WinZip will show its contents as a couple of text files. One of them will be your message in plain text format, which you can extract and read in Notepad etc.[/quote]
Thanks! Your suggestion works.
It is an adequate workaround because I only receive these problem emails occasionally.
