White space is important for .yml files — it might be the indentation which needs a fix

default:
# default configuration options for all environments
# Outgoing emails configuration (see examples above)
  email_delivery_method: smtp
  smtp_address: mail.domain.com
  smtp_port: 587
  smtp_domain: domain.com
  smtp_authentication: :login
  smtp_user_name: openproject@domain.com
  smtp_password: password

note that there are exactly two spaces (not 5) in front of the smtp settings.

I did not know that.

I went back and re-copied the configuration.yml.example and then edited it again. The spacing and format is exactly as it is in the example. The only changes I have made to the configuration file are modifying the e-mail settings and enabling the memcache on line 146. I attached the file again, after re-copying it.

One thing I noticed is that the example has quotation marks around the username and password. It doesn’t work for me at the moment either way, but are the quotation marks necessary?

This time I also attached the complete passenger error text.

Is there something else that I have not installed or configured correctly

I got past the passenger error. Here is the format I have for the e-mail configuration in the configuration.yml file.

# default configuration options for all environments
# Outgoing emails configuration (see examples above)
default:
    email_delivery: 
    delivery_method: :smtp
    smtp_address: mail.domain.com
    smtp_port: 25
    smtp_domain: domain.com
    smtp_authentication: :login
    smtp_user_name: "openproject@domain.com"
    smtp_password: "MyPassword"

However, when I try to do something in open project that requires sending an e-mail notification, I get a 500 error. When I check the log, this is what it says.

I have tried setting the smtp_port in the configuration file to 30 and 587, but the error message is the same, including the port.

I am still stumped on this e-mail issue and have not gotten any farther. Is there something I have done incorrectly, or that I can try?
