I have Apache 2 configured with VirtualHost’s. So I have my domains for example http://mydomain1.com and http://sampledomain.com running on my machine. What about mails now? What about postfix?

For arriving mail:

1. Edit “/etc/postfix/main.cf” and add there:

         virtual_alias_domains = mydomain1.com, sampledomain.com
         virtual_alias_maps = hash:/etc/postfix/virtual
       

2. Edit or add “/etc/postfix/virtual”:

         @mydomain1.com user1
         homer@sampledomain.com user2
       

   This means that all mail for domain mydomain1.com should be delivered to local user account user1 (/home/user1 or whatever). This means also that mails for homer@sampledomain.com will be delivered to local user account user2.
3. Execute:

         cd /etc/postfix
         postmap virtual
         /etc/init.d/postfix restart
       

For departuring mail (mails sent form local accounts to the Internet):

1. Edit “/etc/postfix/main.cf” and add there:

    
         smtp_generic_maps = hash:/etc/postfix/generic
       

2. Edit or add “/etc/postfix/generic”:

         user1@ubuntu-1004-lucid-64-minimal user1@mydomain1.com
       

   So mails sent from local accunt user1 will be sent into the Internet as user1@mydomain1.com.
3. Execute:

         cd /etc/postfix
         postmap virtual
         /etc/init.d/postfix restart

Problem: I wanted to run a rspec in Aptana RadRails as a Test::Unit Test (Alt+Shift+X U) I have a spec/controller/my_controller_spec.rb file generated by rspec_controller generator. While running it in Aptana I got:

./spec/controllers/my_controller_spec.rb:1:in `require': no such file to load -- spec_helper (LoadError)

The solution is to change what the generator generated. Replace in the file:

require 'spec_helper'

with:

require 'spec/spec_helper'

This should help. Running this rspec through rake (rake spec) should work still as well.

Problem:

When doing:

rake thinking_sphinx:index

you get:

undefined method `[]' for false:FalseClass

Solution: remove the empty config/schema.yml file.
