First, it's not very flexible to implement this as global option. You could easily make it per-crontab depending on environment variable like CONTENT_T= YPE. Cron already looks at per-crontab MAILTO environment variable, why not look= at CONTENT_TYPE? Then, cutting contents at first 1024 bytes embedded in the code is error-pr= one. Note well: libmagic has MAGIC_PARAM_REGEX_MAX=3D=3D8192 currently. I'd suggest "CONTENT_TYPE=3Dlibmagic:1024" format when ":1024" part would be optional to redefine default of MAGIC_PARAM_REGEX_MAX. Also, I would not be so sure about "Content-Transfer-Encoding: 8bit" header. 8bit does not mean "any data". According to RFC 2045 https://www.ietf.org/rfc/rfc2045.txt , it means short (998 octets or less) = text strings without null bytes and CR/LF octets in CRLF sequences only. If the = body contains binary data, the "binary" Content-Transfer-Encoding token must be used. Mentioned PNG would violate "8bit" for sure. --=20 You are receiving this mail because: You are the assignee for the bug.=
