Problem

You want to be able to send emails from your development enironment using Postfix in your (K)Ubuntu pc.

Solution

First you would need to install postfix:

sudo apt-get install postfix

and then you would need to change an option in postfix to not use tls, so change /etc/postfix/main.cf:

sudo vi /etc/postfix/main.cf

and change the smtpd_use_tls from yes to no:

smtpd_use_tls=no

restart your postfix server:

sudo /usr/sbin/postfix reload

and then setup your config/development.rb as follows:

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:                 "127.0.0.1",
  port:                    25,
  enable_starttls_auto:    false
}

Problem

You have installed postfix in your local development machine (sudo apt-get install postfix), and you want to test sending emails from the command line using mail email_address@someone.com

 

Solution

You would first need to install the mailutils package:

sudo apt-get install mailutils

then you can send an email by:

mail email_name@example.com
CC: (leave blank)
Subject: Test subject
Main message body

and you can send it by pressing Ctrl+D

Problem

You have setup your Rails app to send out emails using postfix, but you also want to redirect the incoming emais to a different account.

Solution

Edit the postfix configuration file vi /etc/postfix/main.cf and add the following two lines at the bottom:

virtual_alias_domains = outgoing_domain.com
virtual_alias_maps = hash:/etc/postfix/virtual

And then add the redirections to the virtual file with vi /etc/postfix/virtual:

outgoing_email@outgoing_domain.com           other_account@other_domain.com
@outgoing_domain.com                         other_account@other_domain.com

Then run the following two commands to restart postfix:

postmap /etc/postfix/virtual
postfix reload
