Ar_mailer not mailing

Hi all,
i’ve set up ar_mailer. It’s all working except the sending over smtp.
Emails are showing up in the emails table.

in enviroment.rb
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => “”,
:port => 25,
:domain => “”,
:authentication => :plain,
:user_name => “[email protected]”,
:password => “mypw”

Is this correct?

ar_sendmail looks like that:

C:\rails\newsletter>ar_sendmail -ov
expired 0 emails from the queue
found 3 emails to send


But i didn’t got an email.

Does somebody knows why?

thanks dexcs
