Proof of concept required before I continue with large and interesting project.
Create a simply perl script listening on port 587 to respond to a mail request using TLS and OCSP Stapling to meet PCI, HIPPA and NIST compliance.
If possible using NET::SMTP and MIME::Lite however any existing or new module(s) will be fine, however efficiency is very important. It will be tested on CentOS 7 64bit with Perl 5.16.3
protocols = TLSv1.2, TLSv1.1, !TLSv1, !SSLv2, !SSLv3
exclude_ciphers = aNULL, eNULL, EXPORT, DES, RC4, MD5, PSK, aECDH, EDH-DSS-DES-CBC3-SHA, EDH-RSA-DES-CBC3-SHA, KRB5-DES, CBC3-SHA, CAMELLIA128, CAMELLIA256
cert_file=/etc/letsencrypt/live/[login to view URL]
key_file=/etc/letsencrypt/live/[login to view URL]
CAfile=/etc/letsencrypt/live/[login to view URL]
It must be PCI, HIPPA and NIST compliant at [login to view URL]
