I’ve followed with tutorial from:

[http://dev.radiantcms.org/radiant/wiki/HowToUseMailerExtension](http://dev.radiantcms.org/radiant/wiki/HowToUseMailerExtension)

When I send the email error appeared: “Error encountered while trying to  
send email. 550-Verification failed for 550-Unrouteable address 550  
Sender verify failed.”.

Someone had such a problems in the past? For help thanks a lot :).

Artur,

You should try changing the transport method. It’s possible that the  
address the form is being sent to is disallowed via sendmail or your  
SMTP server.

You can change the transport method in config/environment.rb or  
config/production.rb (assuming you’re running in production). This page  
has more information on configuring ActionMailer:

> **[ActionMailer::Base](https://api.rubyonrails.org/classes/ActionMailer/Base.html)**
>
> Action Mailer allows you to send email from your application using a mailer model and views. Mailer Models To use Action Mailer, you need to create a mailer model.

What version of Radiant are you using? Sean just posted today that he  
hasn’t updated Mailer to the new version yet.

Following Hans’es guides I’ve added to config/eniroment.rb file line:

ActionMailer::Base.delivery\_method = :sendmail

Now emails are sending and everything is going fine. Thanks a lot!

Another question: Is there possibility to check if some field in form is  
empty and the don’t send form??

Actually that doesn’t seem to work due to the hack in mailer\_page.rb.  
I’ve solved it by setting the ActionMailer::Base.delivery\_method just  
before the deliver\_generic\_mailer is used. This seems to work fine (and  
I  
already had done the same thing for the 0.5.2 plugin.

Kind regards,

Hans

Artur,

No, but I’ve considered adding it. As with other extensions, we’d  
accept patches.
