I have actionmailer set up. Emails are not being sent, and no errors.

Where can I start my search to debug this?

class Notifier < ActionMailer::Base

default_url_options[:host] = APP_DOMAIN

def email_blast(user, subject, message)
subject subject
from NOTIFIER_EMAIL
recipients user.email
sent_on Time.zone.now
body :user => user.first_name + ' ' + user.last_name, :message => message
end

I do get a return in my log that the email was sent, just no actual email goes through.

Also the reason, that this is not working is because I switched form a cluster to a solo box and some server settings were overwritten. I suspect that is probably the reason why this is not working. Anyone know what specific server settings I would have to look at ?

UPDATE:

ActionMailer::Base.delivery_method = :sendmail
config.action_mailer.default_url_options = { :host => "75.101.153.93" }

I found this in my production.rb . This code was originally here when it worked. Again, I believe that there must be something missing on my server..I did a 'which sendmail' and it returned /usr/bin/sendmail , so I added this :

config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_deliveries = true
config.action_mailer.sendmail_settings = {
 :location        => '/usr/bin/sendmail',
 :arguments       => '-i -t'
}

Redeployed, restarted the server, and tested it. No emails were sent.

The production.log said something was sent :
