Problem trying to configure SMTP

Hi,

I need to configure SMTP without SSL/TLS but i do not find the way to do it. All the configurations i tried finished with this error:

SSL_connect SYSCALL returned=5 errno=0 peeraddr="the ip address and the port" state=SSLv3/TLS write client hello

One of them is:

email_delivery:
delivery_method: :smtp
smtp_settings:
address: "the ip address"
port: 25

Is it posible to use SMTP without SSL in redmine 5.0.1?

I think it would be better to look for the reasons why unencrypted transmission is still necessary

The reasons have been investigated and there is no solution for that. Do you know if there is any way to configure SMTP in redmine without SSL?

Try:
enable_starttls: false
enable_starttls_auto: false
openssl_verify_mode: "NONE"

In my configuration I'm using port 587 and below are the details:

email_delivery:
     delivery_method: :smtp
     smtp_settings:
       enable_starttls_auto: true
       address: "smtp.office365.com" 
       port: 587
       domain: "smtp.office365.com" 
       authentication: :plain
       user_name: "mail@mail.com" 
       password: "your smtp password"

I have tried this configuration but the same error:

enable_starttls: false
enable_starttls_auto: false
openssl_verify_mode: "NONE"

port: 25
        ssl: false
        tls: false
