Hey guys,  
I want to send an email via ROR and I have put this code at the very end  
in the config/environment.rb file-

ActionMailer::Base.delivery\_method = :smtp  
ActionMailer::Base.perform\_deliveries = true  
ActionMailer::Base.logger = nil  
ActionMailer::Base.raise\_delivery\_errors = true  
ActionMailer::Base.smtp\_settings = {  
:address =\> “[my smtp server]”,  
:port =\> 25,  
:domain =\> '[my domain],  
:authentication =\> :plain,  
:user\_name =\> ‘removed\_email\_address@domain.invalid’,  
:password =\> ‘[my password]’  
}

but when i click on send mail button, it shows following error:

Net::SMTPSyntaxError in MailingController#sendmail
