Getting this error everytime i try to use the UserMailer to send an  
email, works in development mode, but not in production.

LoadError (Expected /app/models/user\_mailer.rb to define UserMailer):

Any ideas?

Using Rails 2.0.2, the user\_mailer.rb does define UserMailer just  
doesn’t seem to work anymore when running mongrel in production mode.

here’s my configs  
…

## production.rb

config.action\_mailer.raise\_delivery\_errors = false

ActionMailer::Base.delivery\_method = :sendmail  
ActionMailer::Base.sendmail\_settings = {  
:location =\> ‘/usr/sbin/sendmail’,  
:arguments =\> ‘-i -t’  
}

nothing like this added to environment.rb, am i missing anything?, was  
working before.

stuck!
