And Glitzy MUAs and MTAs tend to be the least RFC compliant of all.

Thunderbird (older versions) had a plugin (Display Mailing List Headers)
that would do it, but the plugin is not compatible with the current
version[s] of Thunderbird.

Any MUA that has a toggle or view to "display all headers" may
indirectly do it if they create "clickable links" for http: and mailto:
directives, e.g., from this list:
