Mailto-Allow#
Usage#
mailto-allow { * | header-field... }
unmailto-allow { * | header-field... }
Note
Before 2026-01-13, these commands were called mailto_allow and unmailto_allow.
As a security measure, NeoMutt will only add user-approved header fields from a mailto: URL.
This is necessary since NeoMutt will handle certain header fields, such as Attach:, in a special way.
The :mailto-allow and :unmailto-allow commands allow the user to modify the list of approved headers.
NeoMutt initializes the default list to contain only the Subject and Body header fields, which are the only requirement specified by the mailto: specification in RFC2368, and the Cc, In-Reply-To, References headers to aid with replies to mailing lists.
