It is with great sadness that we announce the passing, following a brief illness, of Terry, our beautiful friend, brother and one of the most brilliant singers, songwriters and lyricists this country has ever produced. (1/4)

1/ We received a PDF from a third party, created from an Excel workbook. The document was forwarded to a customer and rejected by two different mail gateways due to a "macro detection". However, the original workbook does not contain a macro. Why is the PDF rejected anyway? 🧵
