Hello,

I’ve setup up Mailing on my Rails app. The setup uses smtp with  
(tested) correct settings.  
But all the mails sent through UserMailer have no subject and look  
like this:

(Begin)  
#Debian-40-etch-64-minimal.tmail\>  
Subject: [www.paperc.de](http://www.paperc.de) - Deine Registrierung bei PaperC!  
Mime-Version: 1.0  
Content-Type: text/plain; charset=utf-8

[…](Content stripped)

Could you please help me how to solve this problem?

Hy,

I could solve the problem!  
There was a wrong entry in my /etc/hostname file.  
It looked like this:

(Begin)  
[www.example.com](http://www.example.com)  
#Debian-40-etch-64-minimal  
(End)

I’ve solved this issue by setting the correct hostname, using the `$ hostname www.example.com` command.  
Cheers,

Lukas Rieder
