Email::MIME::Header - the header of a MIME message


version 1.952


This object behaves like a standard Email::Simple header, with the following changes:

  • the header method automatically decodes encoded headers if possible

  • the header_as_obj method returns an object representation of the header value

  • the header_raw method returns the raw header; (read only for now)

  • stringification uses header_raw rather than header

Note that header_set does not do encoding for you, and expects an encoded header. Thus, header_set round-trips with header_raw, not header! Be sure to properly encode your headers with Encode::encode('MIME-Header', $value) before passing them to header_set. And be sure to use minimal version 2.83 of Encode module due to bugs in MIME-Header.

Alternately, if you have Unicode (character) strings to set in headers, use the header_str_set method.


This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
