Hello

I have just installed OpenProject un my ubuntu server. 

I cant connect either to my private or gmail smtp server. It gives me this error message

An error occurred while sending mail (SSL_connect returned=1 errno=0 state=error: wrong version number)

You can set OPENPROJECT_SMTP__OPENSSL__VERIFY__MODE=none if you absolutely need to disable SSL/TLS verification.

On a packaged installation use this command:

openproject config:set OPENPROJECT_SMTP__OPENSSL__VERIFY__MODE=none

Please restart your server after setting this environment variable.

service openproject restart

Best,

Oliver

@Oliver Thanks but unfortunately this did not help the error to be fixed. What is the best way to troubleshoot this? Or are there any more suggestions?

Great thanks

An error occurred while sending mail (SSL_connect returned=1 errno=0 state=error: wrong version number) 

We are trying to O365 Relay and facing this error. 

Here are our configuration: 

"Email Delivery Method : smtp

SMTP Port : 587 

SMTP HELO Domain: openproject.domain.ca

SMTP authentication: login

SMTP username: serviceaccount@domain.ca

Automatically use STARTTLS if available:  True

Use SSL connection: True "

Any recommendation ?
