+
+ %f The full From, e.g. \"John Doe <john.doe@example.invalid>\".
+ %n The mail address, e.g. \"john.doe@example.invalid\".
+ %N The real name if present, e.g.: \"John Doe\", else fall

+ %F The first name if present, e.g.: \"John\".
+ %L The last name if present, e.g.: \"Doe\".
+
+All other format specifiers are passed to `format-time-string'
+which is called using the date from the article your replying to.
+Extracting the first (%F) and last name (%L) is done
+heuristically, so you should always check it yourself.
