Subject prefix must comply with RFC

Description

Named ACL contains directives (PREFIX-SUBJECT or MODIFY-HEADER) for mail header manipulation. However, some of these directives are invalid, for detail error description, see previous log messages.

Such a configuration violates RFCs (2045,...), check properly whether you really need to use such an incorrect Content-Type.

Proxy will continue despite even potential previous error log messages.
