## 6.3.229. sig_dashes

Type: boolean
Default: yes

If set, a line containing ``-- '' will be inserted before your `` $signature''. It is strongly recommended that you not unset this variable unless your ``signature'' contains just your name. The reason for this is because many software packages use ``-- \n'' to detect your signature. For example, Mutt has the ability to highlight the signature in a different color in the builtin pager.
