ActionMailer – SocketError (getaddrinfo: Name or service not known) blues

I launched a new website a week ago and had issues with the action mailer setup used by restful_authentication. For some reason I was receiving the socket error and google wasn’t to helpful either.

So what was the problem?

Well, first I thought it was my setup of Postfix. But it turned out to be my settings for my action mailer. Anyways, the address should not point to your complete domain name, but rather to localhost. Here is the code snippet:

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "localhost", # instead of "smtp.yourdomain.com",
:port => 25,
:domain => "yourdomain.com",
:authentication => :login,
:user_name => "user_name",
:password => "password"
}

Of course the ActionMailer settings should go into your environment.rb file (pre 2.0)

It is just very annoying that none of the docs or tutorials point this out….

Can it be? Rails 2.0.0 Release

After I grabbed the latest version of the Rails source code from svn and I noticed the tag *2.0.0* (December 6th, 2007) in the CHANGELOG. Does this mean I have the official Rails 2.0 source? Maybe, let’s see what DHH announces over the next couple of days.

It would be totally awesome to get the Rails 2.0 official drop over the silly season. Nice down time to explore and get into the new features. Anyways, I think the official release must be very close…

UPDATE:
Yeah, it’s released. Totally awesome!!! You can read more about it at DHH’s post and to get your grubby hands on Rails 2.0, just run gem install rails… Later dudes…

No rhtml, rxml, rjs or delegate template found for signup_notification in /*_mailer

If you are getting this error, don’t fret. Here is the solution to solve this problem. Put the following line somewhere close to the top of your mailer class:

YourMailer.template_root = File.dirname(__FILE__) + '/../views'

You should now be able to send those emails. I found the solution here. Thanks Miroslav…

You can also find more in depth information on what is causing the mailer to blowup from Miroslav’s post…
