In the mailmap file, both addresses should be present, to tie them together:
-Patrick Robb <probb at iol.unh.edu>
+Patrick Robb <patrickrobb1997 at gmail.com> <probb at iol.unh.edu>

Look at other entries with multiple addresses, e.g.:
Thomas Monjalon <thomas at monjalon.net> <thomas.monjalon at 6wind.com>

With that fixed,
