The header field name is not case sensitive. To make the life |
749 |
|
easier for perl users who wants to avoid quoting before the => operator, |
750 |
|
you can use '_' as a synonym for '-' in header field names |
751 |

(this behaviour can be suppressed by setting |
752 |
|
C<translate_underscore> option to C<0> value). |
