Same problem here.
It worked well in redmine 2.2, but today I'm testing 2.3 and mails are not sent anymore.
I always get the error : "SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol".

I kept the configuration untouched from 2.2 to 2.3 :

default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: 192.168.10.126
      port: 25
      domain: 123-opportunity.com
      openssl_verify_mode: none

Adding lines like

enable_starttls_auto: true

... don't make it better.

Also, in postfix logs, I found :

Apr 15 18:53:02 srv-postfix postfix/smtpd[30924]: connect from unknown[192.168.10.239]
Apr 15 18:53:02 srv-postfix postfix/smtpd[30924]: lost connection after UNKNOWN from unknown[192.168.10.239]
Apr 15 18:53:02 srv-postfix postfix/smtpd[30924]: disconnect from unknown[192.168.10.239]

Hope this helps out in finding what happens...

Just solved it.

Add two lines :

enable_starttls_auto: false
openssl_verify_mode: 'none'

Did not solve for me. My configuration is below:

ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:ssl => true,
:address => "smtp.gmail.com",
:enable_starttls_auto => false,
:port => "587",
:domain => "xyz.com",
:authentication => :plain,
:user_name => "redmine@xyz.com",
:password => "1234",
:openssl_verify_mode => 'none'
}

Hey, I'm having the same problems. Notifications worked in 2.2.3, failed in 2.3.1 using the exact same configuration.yml email settings. If I try this:

with: enable_starttls_auto: true
the error I get is: SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol

with: enable_starttls_auto: false
the error I get is: Failed to login to SMTP server: 503 AUTH command used when not advertised

Im trying to play with different settings based on those errors, but what would explain the issue if it worked fine prior to 2.3.x? What changed?

Di you tried changing the authentication method?
I changed it to "login" and it worked, I also removed the option "tls: true".

delivery_method: :smtp
smtp_settings:
      enable_starttls_auto: true
      address: "smtp.gmail.com" 
      port: 587
      domain: "sophilabs.com" 
      authentication: login
      user_name: "user@sophilabs.com" 
      password: "password"
