Cannot disable SMTP TLS through mail library
Net::SMTP now defaults to automatic TLS; the mail interface hasn't been updated to reflect this. It will turn TLS on or to automatic if requested, but has no way to turn it off if requested, because it assumes that it defaults to off in Net::SMTP.
The build_smtp_session method should probably call both smtp.disable_tls and s mtp.disable_starttls before checking its parameters to see if it needs to turn either of those back on.

Looks like you are referring to the mail gem, which is not part of Ruby itself: https://github.com/mikel/mail/blob/8fbb17d4d5364c77cc870769d451bc2739b3a8ce/lib/mail/network/delivery_methods/smtp.rb#L112
