Warning: Use of uninitialized value in concatenation...

Hello Marc,

I installed your milter via
sudo cpanm Mail::Milter::Authentication
Because a test failed in "Net-DNS-Paranoid-0.08" ( tokuhirom/Net-DNS-Paranoid#4 ) I had to use "--force" to install it, then it worked fine.

But when running it with "debug:1" I get lots of these Warnings:

==> authentication_milter.err <==

authentication_milter -h shows that I'm using version 3.20210914
