Configure Postfix To Deliver Mail From Desktop (root, user) To My Gmail Account

I'm using Ubuntu 16.04 LTS and I want to use the command line to send messages to my regular email account. There are administrative tasks that sends mail to root / administrator but to simplify my tasks I want these messages to be sent to my regular email account in Gmail.

I installed postfix first.

#apt install postfix mailutils

Then accepted some basic configurations that were prompted when installing postfix.
    General type of mail configuration?: Internet Site
    System mail name: a hostname that will be used in mail headers, a FQDN is preferred, desktop, home
    Root and postmaster mail recipient: root
    Other destinations to accept mail for: $myhostname, desktop, localhost.localdomain, localhost
    Force synchronous updates on mail queue?: No
    Local networks: [::ffff:]/104 [::1]/128
    Mailbox size limit: 0
    Local address extension character: +
    Internet protocols to use: all

If you need to return to these settings, type:

#dpkg-reconfigure postfix

You need to create a password file which Postfix will use to authenticate with Gmail. In Ubuntu such a file should be placed in /etc/postfix/sasl/sasl_passwd. So I used my favorite text editor and:

#nano /etc/postfix/sasl/sasl_passwd

I entered:

"[]:587  emailaddr:app password"            - do this without the quotes, okay.

Save and close the file.

Protect this file.

#chmod 600 /etc/postfix/sasl/sasl_passwd

Make sure the following entries are present in /etc/postfix/ so open the file and add or modify the file.

relayhost = []:587
smtp_use_tls = yes
smtp_sasl_auth_enable = yes
smtp_sasl_security_options =
smtp_sasl_password_maps = hash:/etc/postfix/sasl/sasl_passwd
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

Use postmap to compile and hash the contents of /etc/postfix/sasl/sasl_passwd. So type:

#postmap /etc/postfix/sasl/sasl_passwd

Then restart postfix by typing:

#systemctl restart postfix.service

That's it. You can check your work by sending a test email.

$echo -e "Hello. This is a test message."|mail -s "Test Message"

America Must Evolve Fast Or Die

This was a music festival concert venue in Las Vegas, Nevada. A shooter in the 32nd floor of a nearby hotel across the general area opened fire then shot himself. He killed 59 people in what reports call the biggest mass shooting in modern American history to date.
America must learn from the lessons of previous mass shootings otherwise this tragedy will happen again. Reasonable animals evolve when their lives and the life of the pack or group are threatened. They change how they face the problem and not just move on. They don't dismiss reality. They recognize the problem and listen to reason. For those who say nothing can be done, you're wrong. There is something America can do. It is not premature to talk about gun control. This is the time to talk about it.

GnuCash In Arch Linux

I updated a number of packages today and Gnucash won't start. I immediately went to the Archlinux website to see what's happening. I can't seem to find the package in the community repo. There's a thread in AUR on how to compile Gnucash by hand no AUR helpers.

But I tried to compile goffice and webkit2, needed packages for Gnucash-git. No. It doesn't work for me.

Funny but I'm now using my Android Tablet with Gnucash app to record transactions. This is working. We need to have the stable GnuCash back. This is a stop gap on my part. Transactions don't stop when computers stop. Please don't make me go back to paper.

Star Wars: The Last Jedi Poster

The Last Jedi is coming this December 2017. I can't wait. My guess is we can watch it later in the Christmas season or even later than the New Year 2018. The Filipino Film Festival season usually starts the 15th December up to January 7th. Only Filipino films are shown in theaters. Unless there's a special run, we would see it much later.
