The following tutorial shows how to setup a local postfix installation on a
ubuntu based OS that accepts mail from
127.0.0.1 and relays every mail that
it receives to the local root account.
This setup is very useful in e.g. a development environment if you are involved
in applications with send email functionality.
Optionally you can install mutt command line email client to read the email.
$ apt-get install postfix $ dpkg-reconfigure postfix
Now we need to configure postfix to route all incoming email to the local root
account. During the previous step
dpkg-reconfigure postfix you have
configured postfix to forward all mail for the local root user to another local
$ postconf -e 'home_mailbox = Maildir/' $ postconf -e 'inet_interfaces = 127.0.0.1' $ postconf -e 'virtual_alias_maps = regexp:/etc/postfix/virtual' $ postconf -e 'virtual_alias_domains =' $ echo '/.*/ root' > /etc/postfix/virtual $ postmap /etc/postfix/virtual $ service postfix restart
Most of the above configuration settings are taken from this site. You can try sending an email using telnet like this (hit enter after every line):
$ telnet 127.0.0.1 25 HELO some.server.localhost mail from: email@example.com rcpt to: firstname.lastname@example.org data To: email@example.com From: firstname.lastname@example.org Subject: This is a test email This is a body text .
You should see a lot of
250 2.x.x Ok responses. Quit telnet and check the
logs if the email was received by the local postfix installation:
$ tail /var/log/mail.log
If you follow these steps you will install mutt, a command line email client so you are able to read the messages that you are sending to yourself :-).
$ apt-get install mutt
We configured postfix to use the popular Maildir format instead of the default mbox format. Maildir is better since it does not suffer of race condition issues that mbox has because each email is stored in it’s own file.
Create a file
.muttrc in the users
$HOME directory with the following
$ cat ~/.muttrc set folder="~/Maildir" set mask="!^\.[^.]" set mbox="~/Maildir" set record="+.Sent" set postponed="+.Drafts" set spoolfile="~/Maildir"
Now you should be able to open
mutt and see the email you send yourself
earlier. Take your time to explore and learn mutt.
