hi i am using technoweenie-restful-authentication plug-in for  
authentication in my application. i want to send a activation link to  
the user’s mail-id.  
for that i need to set the smpt server for our rails application, for  
that i added the follwing code in config/environment.rb file

ActionMailer::Base.delivery\_method:smpt  
ActionMailer::Base.smpt\_settings = {  
:address =\> “localhost”,  
:port =\> 25,  
:authentication=\> :login,  
:user\_name =\> “my\_username”,  
:password =\> “my\_password”  
}

but when i try to run the server it gives the following errors

G:\my\MyMovies\>ruby script/server  
=\> Booting Mongrel  
=\> Rails 2.3.3 application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)

Did you include these…

ActionMailer::Base.raise\_delivery\_errors = true  
ActionMailer::Base.perform\_deliveries = true  
ActionMailer::Base.delivery\_method = :smtp

It looks like you’ve got this towards the top of environment.rb, i.e  
before the bit that runs the initializer: you don’t want this, the  
initializer is the thing that loads rails, so before it none of the  
rails framework (ActiveRecord, ActionMailer etc.) is loaded. You’ve  
also got a few typos in there.

Don’t use environment.rb, use instead: “config/initializers/  
action\_mailer.rb”. Set it to read:

ActionMailer::Base.delivery\_method = :smtp

ActionMailer::Base.smtp\_settings = {  
:address =\> “localhost”,  
:port =\> 25,  
:authentication=\> :login,  
:user\_name =\> “my\_username”,  
:password =\> “my\_password”  
}

NOTE 1: delivery\_method = :smtp  
NOTE 2: smtp not smpt – two places

That rather than having environment.rb become a dumping ground you  
have a descriptively named set of files. Another incentive is that  
initializers run before your models are loaded (in production mode)  
whereas something at the bottom of environment.rb runs afterwards  
which can sometimes be problematic.

What’s the rational behind using initializers instead of environment  
files?  
We are (and have been for some time) setting the smtp options in the  
environment files with great success.
