Registration: some confirmation emails not sent?

[rfc2822]

Hello,

[NodeBB 0.9.3/master from today] Anyone here who also has the problem that some (only some) of the registration confirmation emails are not sent? In the mailserver logs I can see that NodeBB doesn't even try to send the mails. Other email addresses work fine. So about ~ 10% of all registrations can't be completed because the registration email is never sent.

GitHub issue: https://github.com/NodeBB/NodeBB/issues/4034

Can you maybe check whether you have ~ 10% pending registrations too, which can't be completed because the mails are not sent?

I have now disabled the requirement for email confimation, but I guess this is not a long-term solution.

@rfc2822 do you use a external mailer. Or local from the NodeBB?

Local, from NodeBB. Email sending works (also the test email in Manage / Email), but for some email addresses, no email is queued to the (local) server.

Are they common providers like Gmail, Microsoft or Yahoo? (<- lol)

Not only. Most of them have common provider domains, others have own domains.

Hmm, I shall do some testing on my end, see if I can get anything. If its possible on your end try running ./nodebb dev see if you can track a error from there regarding the emails.

It just shows:

8/1 16:10 [42934] - verbose: [emailer] Sending email to uid 1034
8/1 16:10 [42934] - verbose: [emailer] Sending email to uid 1030
…

when I click on Manage / Users / Send validation email. However, there's no incoming email on the local mail server.

Problem identified and fixed: it was the direct transport, which is not a good choice (should be sendmail or smtp instead). See https://github.com/NodeBB/NodeBB/issues/4034#issuecomment-170894390

[Pappmann]

which file and which part of the file we have to change to switch from direct to sendmail?

[rfc2822]

@Pappmann https://github.com/NodeBB/NodeBB/blob/v0.9.x/src/emailer.js

For a quick hack, just change the second 'direct' to 'sendmail' in line 17.

For a real patch, change the name in the array, too (rename the first direct to sendmail), and then change it in line 118, too.
