Hi all - new here to Open Project and I am trying to configure my email. I edited the config.yml page got rid of everything except ( see below ) and I keep getting the same error when I am trying to send a test email.

An error occurred while sending mail (hostname “localhost” does not match the server certificate) any ideas?

1. default configuration options for all environments
   default:
   # Outgoing emails configuration (see examples above)
   email_delivery_method: :smtp
   smtp_address: smtp.example.net
   smtp_port: 25
   smtp_domain: example.net
   smtp_authentication: :login
   smtp_user_name: “openproject@example.net”
   smtp_password: “my_openproject_password”

1. specific configuration options for development environment
2. that overrides the default ones
   development:
   email_delivery_method: :letter_opener

1. Configuration for the test environment
   test:
   email_delivery_method: :test

Hi Robert,

setting the following option should work:

smtp_openssl_verify_mode: ‘none’

You should include all smpt settings in ‘config/configuration.yml’

Hi Christian

I have a problem with sending email also, in my case I have to return this message: An error occurred while sending mail (getaddrinfo: Name or service not known).
I’ve done research and found no solution.

Hi Luiz,

sounds like the specified smtp server doesn’t exists you should check your smtp settings again.

I made all the settings according to my provider.

1. default configuration options for all environments
   default:
   email_delivery_method: :smtp
   smtp_address: “openproject@arcadian.com.br”
   smtp_port: 80
   enable_starttls_auto: “true”
   smtp_domain: “smtpout.secureserver.net”
   smtp_authentication: “plain”
   smtp_user_name: “openproject@arcadian.com.br”
   smtp_password: “xxxxxx”
   smtp_openssl_verify_mode: “none”

It worked, thanks Christian

Hi Christian!

Thanks for your help. I added the line like you said, but still the same. Here is what I have

1. Outgoing emails configuration (see examples above)
   email_delivery:
   delivery_method: :smtp
   smtp_settings:
   address: smtp.gmail.com
   port: 587
   domain: smtp.gmail.com (what is the domain?)
   authentication: :login
   user_name: “mrw5641@gmail.com”
   password: “”
   smtp_openssl_verify_mode: ‘none’

It seems like no matter what settings I change it reverts back to local host error. (even with all settings removed)

Hi Christian, there is on thing I think you are missing in the installation instructions with the email.

I found that adding config.action_mailer.smtp_settings = { enable_starttls_auto: false } to the application.rb will get rid of the local host problem and that it allows for test emails.

Hi Christian sorry to keep bothering you ;-). I have two servers running open project with the same settings. I got the email working on my test server fine. I am trying to deploy the email on my second server. But I keep getting the error with

Failure in opening uri #<URI::Generic:0xe9a1ee8 URL:/home/openproject/openproject/tmp/letter_opener/1388784738_5a0907d/plain.html

Would it help to delete that file and then regenerate?

here is the full error.

An error occurred while sending mail (Failure in opening uri #<URI::Generic:0xe523754 URL:/home/openproject/openproject/tmp/letter_opener/1388785321_de7db95/plain.html> with options {}: Can’t convert URI::Generic into String.)

Hi Michael,

your second servers runs in production or in development mode?

Best

Hi Christian. Well, I was working with 2 servers,I got one to work — I didn’t have that error. I am just trying to resolve the error above. It is running in production.

Hi Michael,

I thought the second server runs in production which explains this error a bit because ‘letter opener’ ist only available in development mode.
Did you set the following setting for production?

email_delivery_method: :letter_opener

instead of

email_delivery_method: :smtp

Christian

I will check that out. I think right now it is set for smtp.

I will try it

Thank you!

Not sure what else to do. I tried both settings in Development and I still get the same error. It seems no matter what I try the same error keeps popping up.

I managed to get past that error finally. by changing a setting in development.rb from letter_opener to smtp.. Now I am getting this .

An error occurred while sending mail (Connection refused - connect(2))

yay. I got it to work!

Thanks Christian!

Hello All,

I successfully configured OpenProject in Ubuntu Environment. Also put email configuration as mentioned in config file. Now, when I am trying to send a test mail then the application shows email sent successfully but I can’t receive email notification. I check log also it will show at the end:
“Completed 302 Found in 353.4ms (ActiveRecord: 32.0ms)”

My Email settings are:

1. default configuration options for all environments
   default:
   email_delivery_method: :smtp
   openssl_verify_mode: ‘none’
   smtp_address: smtp.example.com
   smtp_port: 25
   smtp_domain: example.com
   smtp_authentication: :login
   smtp_user_name: “openproject@example.com”
   smtp_password: “****”

Hello Everyone;

Does anyone knows the settings to send mail using Office 365?…

I get this error when trying to send a test email:

An error occurred while sending mail (504 5.7.4 Unrecognized authentication type )

I’ve tried PLAIN and LOGIN on SMTP_AUTHENTICAITON but get the same error.

This configuration should work, because I already have another service (ServiceDesk Plus) with the same email account… the only thing is that in SDP I don’t have to set that parameter.

Thanks in advanced.

For the main Topic

hostname “localhost” does not match the server certificate)

I fixed it in another way.

In your config folder, in Application.rb, type the following line.

config.action_mailer.smtp_settings ={enable_startssl_auto:false}

I used sendmail, with a no-reply address, but it should work for any other config with that error message.
