may need :ssl in smtp_setting

[OmmyZhang]

Expected behaviour

Can send email

Actual behaviour

"EOFError: end of file reached"

Steps to reproduce the problem

Use SMTPs Protocol (port 465)

Specifications

After I changed to use a smtp server that only provides SSL(port 465), no TLS(port 587), I find I can't send emails and always get "EOFError: end of file reached". Finally, I solved this problem by adding :ssl => true in smtp setting.

So, maybe there should be :ssl => ENV['SMTP_SSL'].presence, in config/environments/production.rb, just like :tls => ENV['SMTP_TLS'].presence,.

(or maybe there's already some way to configure this but I miss it?)
