It appears this is recognized as a .cab file. There was a bug in older versions of amavisd-new that may have allowed .cab files to pass (not be recognized) so this may be why you are seeing this for the first time. I work around this type of problem by allowing the files I want. For example, I block .zip/.rar files, but allow certain files to pass before I do. This sample also shows where .snp files are allowed before .cab files are blocked: <...> majority of banning goes here <...> [ qr'.\.(doc|snp|ppt|xls|gdf|pdf)$'i => 0 ], # allow this stuff qr'.\.(zip|rar)$'i, # block zip qr'^\.(exe-ms)$', # banned file(1) types qr'^\.(exe|lha|cab|tnef|dll)$', # banned file(1) types ); Also, users should be warned not to name files as double extensions: (prova.snp.doc) as they may get banned for that reason.
