Nodebb and emails

[phenomlab]

OK, after taking a look at this, I’ve done the following

1. Set your nodebb instance to use custom smtp and send via smtp.fastmail.com
2. Save and test

I now get the error

Invalid login: 535 5.7.0 Sorry, you need to create an app password to use this service. Please see fastmail.com/help for more details.

This means you need to configure an app inside fastmail to send emails.

After you’ve done this, it should work

@phenomlab ok thanks will try with app password
I wonder why it needed custom setup

[phenomlab]

@Panda likely because the predefined settings are out of date. Realistically, nodebb devs can’t possibly maintain correct settings for mail services they do not control.

Finally it works, thanks.
I had to regenerate the app password on fastmail, and the test email send is working.

Out of interest, in your custom set up of fastmail, how did you know to pick SMPT port 465?

@Panda experience, plus this

Follow up question:
Re this past comment on NodeBB
“There are three ways to send emails from NodeBB:
Emailer plugin. (Like sendgrid). These plugins allow you to use email distribution services like Sendgrid, MailChimp, etc to send out emails. This helps about issues of spam filtering and such, because it’s their email servers handling all of that. These plugins contact the email service via http and then the service sends your emails out.
SMTP transport. This is built into NodeBB. It is only used if you don’t have an emailer plugin active and you enable “Enable SMTP transport” (previously “Use an external server to send emails”) in the email settings. The SMTP transport allows you to either pick from a list of known services (provided by the underlying module nodemailer) or to provide custom settings yourself. It contacts the server via SMTP and then the SMTP server sends your your emails.”

Im still confused about which of these methods is best in theory
When you use an internal post fix server does this use (1) Emailer plugin or (2) SMTP?

@Panda it will use SMTP. In all cases, I never use any plugin to send email. I’ll always send it raw.
