How to use only Nullmailer to send emails with Symfony

Asked 2020-Sep-13 at 12:39

I have a Ubuntu server with nullmailer installed on it to relay send emails to an actual SMTP server. Everything is working as intended when I execute the following command at the CLI.

Since nullmailer is such a simple daemon it doesn't provide a local smtp server so you'll have to use the sendmail transport.

The MAILER_DSN should be something like sendmail://localhost or sendmail://your-host-name.

QUESTION

How to send email of a G-Suite alias domain via Ubuntu 18.04 Server

Asked 2020-Feb-10 at 21:02

Scenario

I have domain.com on GSuite. Then I have aliasdomain.com (which is set as an alias domain for that in GSuite.) And I have a GSuite User admin (which is both admin@domain.com and admin@aliasdomain.com just like I want them to be. Emails sent to either are received via gmail's admin@domain.com account, all good.

Now I have an Ubuntu 18.04 Server from which I would like to send mail as admin@aliasdomain.com. I have learned that I need to use Google SMTP to accomplish that.

What I've tried

I've also learned that nullmailer is light and since I only wish to send a mail very occasionally, it is perfect, so I'd like to use that preferably, but Postfix or sendmail can also be an option, if that doesn't work.

Unfortunately I have very limited understanding of anything related to mail transfer agents, etc. But I've tried my best to search for a resource or a guide for this particular scenario, but most of them are quite advanced to me, and they assume the reader to be very well-versed.

What I need

How do I set up sending mail using the above scenario? I am hoping someone kind enough to guide me in this regard.

Thank you very much.

OK, after some trial and error, I finally got it all working. Here's a step-by-step tutorial (sort of) if anyone is interested:

G SUITE:
1. Log in to admin@domain.com's gmail and enable Send mail as (refer to its section of Step 3 here, under Send messages from your alias address
2. Log in to domain.com's Google Admin Console > Apps > GSuite > GMail > End user access > Enable Allow per-user outbound gateways
UBUNTU 18.04 SERVER:
1. Install nullmailer sudo apt-get install nullmailer (then accept all default values for now, we're changing them below)
2. cd /etc/nullmailer
3. sudo nano defaultdomain and replace all text with aliasdomain.com
4. sudo nano adminaddr and replace all text with admin@aliasdomain.com
5. sudo nano remotes and replace all text with smtp.gmail.com smtp --port=465 --auth-login --user=admin@domain.com --pass=YOURPASSWORDFORadmin@domain.comGMAILACCOUNT --ssl (Read important security note below before doing this step!)
6. sudo systemctl enable nullmailer
7. sudo systemctl start nullmailer
NULLMAILER:
1. Nullmailer should now be ready
2. Test it: printf "Subject: Nullmailer test\nFrom:admin@aliasdomain.com\nTo:example@hotmail.com\n\nTest from Nullmailer" | sendmail -v example@hotmail.com
3. Check example@hotmail.com Inbox for email from admin@aliasdomain.com (you might have to look in Spam folder and mark it as Safe for future.)

IMPORTANT SECURITY NOTE

Before attempting Step 2.5, You must either enable two-factor authorization for admin@domain.com and use App Passwords OR enable Less secure apps. It's your decision ultimately.
