@marusaky Are you using your own SMTP server, or an external one ?

my own, from the hestia cp

@marusaky see this example

Obviously, you’ll be using your own credentials and mail host, but ensure you have the same selections as I do.

still doesn’t work… I have tried to put even mail. at smtp host, but still the same, I also tried with all the connection security, nothing… and I don’t think it’s a problem from my e mail, I set it up with SSL encryption, DNS is also set… tried with port 465 also… any ideas? thank you!

@marusaky is your server permitted to send outbound email directly? Several hosting companies disable this by default so you might need to contact them and ask them to release or permit.

Another test would be to see if the server is in fact listening. You can do this with a simple telnet command, for example

telnet server.com 587 where you obviously replace server.com with the actual mail host name. If you get a response, then it’s working. If nothing, then you’ll need to call the hosting company as I suggested.

yep, the e mail is working as it should, I even contacted the support, they helped me set up the e mail again and entering it in the nodebb settings fields, but it still doesn’t work, I am going crazy lol

@marusaky Happy to take a look if you want to provide me with temporary admin.

of course, I will send you the details

@marusaky After checking:

1. Email appears to work without issues. I am able to send new user registration emails with no issues
2. Test template email also works fine without issues
3. Emails sent to GMAIL accounts are sent to Spam. This is due to no DMARC DNS record being configured. You should also check that the A and AAA records (for Ipv6) are present in DNS
4. Your server IP address appears on one blacklist. You should contact the owner of this list to have the block removed

@marusaky it looks like your SMTP connector in NodeBB is set to use StartTLS (which makes sense on port 587), although the message seems to be discarded. I changed this so it looks like the below

This seems to work in my testing. Let me know. Essentially, we change StartTLS to None

@marusaky seems there are some DNS records missing or are there but not configured correctly. I’ve corrected this so hopefully (in the next 48 hours) the spf, dmarc, and dkim should function as required and mail won’t be classed as spam.

As discussed in PM though, some mail servers will still send messages to spam from new domains less than x days old. This is standard security practice and not much you can do to avoid unfortunately, but what we have is best practice.

@marusaky I checked again this morning and it seems that messages are still going to spam when using Gmail, so a little more investigation and configuration is needed. However, it seems to work fine with other domains I tested.

Will look into this further.

@marusaky based on the work completed thus far (in relation to PM exchanges), I’m going to mark this completed. Sending email from the server itself works fine without issue, and DNS appears to be clean (valid SPF, DMARC, and DKIM records).

It appears that only Gmail marks incoming messages from your domain as spam - perhaps because of the domain age, which there is nothing we can do to prevent this. Mail delivery to all other domains appears to work fine in al of my tests.
