The header must not contain 8-bit characters, such one which needs 8 bits to represent. For incoming external messages this is nearly impossible to rely on 7- bit headers. Even our very heterogenous intranet traffic burdened us with ongoing complaints of sticky headers. We had several internal Lotus Notes servers (or clients?) which constantly generating 8-bit characters in the Date: header with translated month names for the local language. However, these might be out-dated installations ... It would be great if all developers of MUAs, MTAs and other message generating stuff test their software against an Amavis environment before they start distributing it ...
