checkpatch doesn't really have an rfc822 parser and would
likely require some fairly involved changes to use one.

For instance: adding
---
 scripts/checkpatch.pl | 1 +
 1 file changed, 1 insertion(+)

diff --git a/scripts/checkpatch.pl b/scripts/checkpatch.pl
index f3b8434..959b8ef 100755
--- a/scripts/checkpatch.pl
+++ b/scripts/checkpatch.pl
@@ -1164,6 +1164,7 @@ sub parse_email {
 
 	$name = trim($name);
 	$name =~ s/^\"|\"$//g;
+	$name =~ s/\s*\([^\)]+\)\s*//;
 	$address = trim($address);
 	$address =~ s/^\<|\>$//g;
 
---

Into the parse_email function to strip rfc822 comments from
email addresses would just create a couple different warnings.

For now, how about adding --ignore=NO_AUTHOR_SIGN_OFF
