Google SMTP for the email

Description

I am unable to setup the email SMTP via Google domain. I did remove 2FA and enable pop3 and imap in the gmail settings. I also enable the settings for unauthorized app auth in the google admin console.
Everything seems to be working fine, but it doesnt send any emails at all.

I20210429-15:21:44.542(-4) The $MAIL_URL is ‘smtp://…:465’. You probably want ‘smtps://’ (The ‘s’ enables TLS/SSL) since ‘465’ is typically a secure port. undefined

Also these are my smtp settings:

Protocol: smtp
Host: smtp.gmail.com
Ignore TLS and pool activated
port: 465
username: the entire email with @
Password: same as gmail
From Email: Not sure, I put admin@csbtech.ca, that section was a bit confusing.

You will need secured Email for Gmail - smtps

So either port 465 or 587 with ignore TLS False

Username is you Google username, and your email is the actual email From address

So you might be joe.blogs@gmail.com

You can actually login to Google as ‘joe.blogs’ but your From address will be ‘joe.blogs@gmail.com’

Couldn’t you get around this by setting up an SMTP server inside your network that does outbound TLS to Google? I suppose you could put it in your approved senders list.

A good alternative, but running your own mail server securely, and without it getting blocked by Google, is not for the faint hearted!

@john.crisp I did exactly what you suggested and it does not work.

Protocol: smpts
Host: smtp.google.com
Username: username without @
Password: same as gmail
From email: username and @ to create full email
Ignore TLS: not active (false)

If I select port 587 then I see this in logs

Exception in defer callback: [Error: 140039672534912:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332: ] {   library: 'SSL routines',   function: 'ssl3_get_record',   reason: 'wrong version number',   code: 'ESOCKET',   command: 'CONN' }

If I select port 465 with same other settings I see this in logs

You may need to create an ‘app’ password if you have 2fa, this url is printed in my logs

Unfortunately I don’t have 2fa enabled. and get the same ssl3_get_record wrong version number error for port 587
