Action Mailer not working with sendmail

Question

I'm trying to send a mail with sendmail. When sending the mail, I don´t get any errors in the logs, but when I look into my mailbox, the mail isn´t there, not even in the spam folder. I get some infos in the mail.log file from my var/log directory, but can´t really figure out, what I have to change, to get it working.

Here´s my development.rb part:

config.action_mailer.delivery_method = :sendmail
config.action_mailer.raise_delivery_errors = true

I tried with two different addresses and got different messages: this is from my mail.log:

In my user_mailer.rb I have this:

default :from => "[email protected]"

Also I tried

config.action_mailer.sendmail_settings = 
    { :arguments => '-i -t -f [email protected]'}

then the mail.log still looks like this:

I tried to telnet mx.freenet.de 25 and got a connection. I would really appreciate any help.

Thanks!

Answer 1

ActionMailer is working correctly and sending the message to postfix via the sendmail api.

But postfix is bouncing the message because the sender machine name in the HELO command is localhost.localhost.

Set the sender's host and name in rails and it should work better.

docs

It could be that you need to set the host at the operating system level (not rails). Ask on the superuser list. See what happens when you give the hostname command to the OS. If it returns "localhost.localhost" then that's the first problem to fix.
