Add an option to toggle the MSA port exemption from PTR on and off.
Include and option so that the MSA (port 587 by default) can be subject to the same kind of filtering as other SMTP ports to help with filtering for compromised accounts.

Hello Hans,
Thank you for sharing your idea to enforce PTR lookups on MSA ports. It will be considered for future versions.
