Description

Hello community,

I am trying to get e-mail notifications work with Redmine 5.0.2.stable and Microsoft Exchange 2013 Mail Server.

I followed this instructions (https://www.redmine.org/projects/redmine/wiki/howto_configure_redmine_to_mail_to_ms_exchange_server) for the configuration and the main lines of my configuration.yml just looks like this:

production:
  delivery_method: :smtp
  smtp_settings:
    address: mail.domain.com
    port: 25

I needed a SMTP program so I installed sendmail first and got an SSL error. Then I uninstalled it and installed postfix instead but I got the same SSL error which is:

"An error occurred while sending mail (SSL_connect returned=1 errno=0 state=error: unexpected eof while reading)" 

This error appears when I click on send test mail on the e-mail notification tab under the main configuration.

I checked both apache and redmine logs but I didn't find useful information to understand what's happening.

Could you please help me with this problem?

This is some of the information of my environment:
