I tried git send-email for the first time today and it failed with:

$ git send-email ....
....
Not using SSL_VERIFY_PEER due to out-of-date IO::Socket::SSL.
To use SSL please install IO::Socket::SSL with version>=2.007 at $HOME/Logiciels/miniconda3/envs/git/lib/5.26.2/Net/SMTP.pm line 270

$ perl -e "use IO::Socket::SSL;"

For anyone reading, the steps to fix this issue would be:

• create a conda-forge package for the IO::Socket::SSL module (should be easy using conda skeleton cpan, check the conda build documentation and https://conda-forge.orgs/docs
• once the perl IO::Socket::SSL package is merged, add it as a dependency of this here package and make a PR
