SMTP setup issue

Thanks Jon,

The n8n stanza of my docker compose looks like this

 n8n:
    image: n8nio/n8n
    restart: always
    ports:
      - 5678:5678
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=${N8N_BASIC_AUTH_USER}
      - N8N_BASIC_AUTH_PASSWORD=${N8N_BASIC_AUTH_PASSWORD}
      - N8N_HOST=${SUBDOMAIN}.${DOMAIN_NAME}
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - NODE_ENV=production
      - WEBHOOK_URL=https://${SUBDOMAIN}.${DOMAIN_NAME}/
      - GENERIC_TIMEZONE=${GENERIC_TIMEZONE}
      - N8N_EMAIL_MODE=${N8N_EMAIL_MODE}
      - N8N_SMTP_HOST=${N8N_SMTP_HOST}
      - N8N_SMTP_PORT=${N8N_SMTP_PORT}
      - N8N_SMTP_USER=${N8N_SMTP_USER}
      - N8N_SMPT_PASS=${N8N_SMTP_PASS}
      - N8N_SMTP_SENDER=${N8N_SMTP_SENDER}
      - N8N_SMTP_SSL=false
    volumes:
      - ${DATA_FOLDER}/.n8n:/home/node/.n8n
      - ${DATA_FOLDER}/local_files:/files

Double checking the environment variables, they all exist inside the droplet (and inside the container):

root@ubuntu:~# echo $SUBDOMAIN
dREDACTEDa
root@ubuntu:~# echo $DOMAIN_NAME
tREDACTEDy
root@ubuntu:~# echo $N8N_EMAIL_MODE
smtp
root@ubuntu:~# echo $N8N_SMTP_HOST
smtp-relay.gmail.com
root@ubuntu:~# echo $N8N_SMTP_USER
nREDACTEDy
root@ubuntu:~# echo $N8N_SMTP_PASS
*REDACTEDy
root@ubuntu:~# echo $N8N_SMTP_SENDER
nREDACTEDy

I am not using any custom email templates (at the moment) does that matter? Do I still need to create a (empty) directory shared into the container for n8n to think that email is set up correctly?

Hey @phpguru,

For some reason this didnā€™t appear in my notifications, those settings look ok the only thing I can think of is maybe it canā€™t connect to the smtp relay address.

If you set the server to use the gmail smtp server does that work?

23

Nope its still non functional. Iā€™ve tried literally dozens of various configs, restarting, etc., plus the issues Iā€™m having on my other thread with random errors trying to reset it and start from scratch, Iā€™m at a loss and have never had this much trouble setting up anything, ever.

Hey @phpguru,

That is very strange, When I used the gmail smtp server a while back it worked with no issues. What port are you using and what do you have the SSL option set to?

25

You configure SMTP settings directly in the interface. After logging in, find the settings or configuration section, enter your SMTP details, and save. Thereā€™s no need to edit files manually.
I recently started a new instance of SMTPget here, however before it can function, a few more settings must be made because it uses StartTLS and port 587 instead of 465.

Youā€™ll typically configure SMTP details in the N8N configuration file. Look for a file named ā€œconfigā€ or ā€œconfig.jsā€ in your N8N installation directory. Within that file, youā€™ll find sections for SMTP settings where you can input your details. If youā€™re unsure, you may want to consult the N8N documentation or look assistance from the N8N community for step-by-step guidance.

27

You can configure SMTP settings for N8N in the .env file located in the root directory of your N8N installation. Add your SMTP details like N8N_SMTP_HOST , N8N_SMTP_PORT , N8N_SMTP_USER , and N8N_SMTP_PASS in that file. Restart N8N to apply the changes. I recently started a new instance of Digitalaka here, however before it can function, a few more settings.

28

I wish I had a section where I couold do it, but I have not.

29

Modify the .env file did nothing to me too.

Make sure that your host is not blocking all SMTP ports. Like in my case DigitalOcean was blocking them. After that we had to move to another Host
