Flarum 1.0.4, Registration validation Emails are not working

thimiraonline

I am new to Flarum and set up it successfully. But there is a problem. Registration validation emails are not delivering. SMPT not working.

Is it a bug or how to resolve this? Should I contact hosting to open several ports?

thimiraonline cloudflare plays no role with outbound traffic.

The port is mentioned in your error:

thimiraonline 465

luceos

Where are you hosted? Some providers are known to block outgoing ports by default for new accounts; this includes digital ocean for instance.

thimiraonline

luceos I have hosted it on Linode. If they have blocked the ports, what should I tell to them? And there is another situation. I am on Cloudflare and SSL is on Full (strict) mode.

Finally, we have found what's wrong with the Mailgun API email setup in Flarum 1.0.4.

We have to put the US or EU as mailgun region at setup. But in /var/www/community/vendor/flarum/core/src/Mail/MailgunDriver.php shows like this. I set mailgun region to api.mailgunnet and now its work fine.

luceos

thimiraonline that you want to send email so that your users can sign up.. Not a big deal 😉

thimiraonline

luceos that you want to send email so that your users can sign up.. Not a big deal 😉

luceos And there is another situation. I am on Cloudflare and SSL is on Full (strict) mode. Is it a reason for this?

And what are the ports that they should unblock?

thimiraonline

luceos I opened a ticket and told them to open 25, 468 and 587.

maybe this will solve your problem
Set mail and webmail options to dns only, not proxyed

luceos

czayorijinal my apologies, but this is not really helpful. These DNS records are for receiving email, not sending. Both of these (webmail and mail) also have no direct relation to email delivery, except if you run a control panel that need these records. The records that matter for receiving email are the MX records. If you want to prevent sent email from being marked as spam you also will need to set up proper SPF and possibly DKIM .

luceos

thimiraonline isn't this covered in their docs (https://documentation.mailgun.com/en/latest/api-intro.html#base-url), I wasn't even aware you were using their API -- should have asked for you mail settings I guess 🙈

thimiraonline

luceos I am using SendGrid for years and this is the first time I am using Mailgun. Anyway now it's working. Nice work bro. Do you have any idea about Push notifications? I want to implement that also. Then someone can get notified when he/she got an answer.

thimiraonline u can set these permission through admin dashboard or https://discuss.flarum.org/settings
