I think the solution is very obvious, but I can't find what I'm doing wrong.

Kakifrucht

Are you trying to send encrypted?

MrPowerGamerBR

Kakifrucht Thanks for saying that! That was the problem!

If someone has the same problem, here is the solution:

UPDATE `flarum_settings` SET `key`='mail_encryption',`value`='' WHERE `key` = 'mail_encryption'

I was following another tutorial, when I got to this step, the user who made the tutorial set the mail_encryption to ssl, so, I set the same thing...

The solution is: You need to set the mail_encryption to "" (this means: nothing at all (DO NOT SET TO NULL))

Kakifrucht

I wonder if it is possible to enable encryption though.

luceos

Kakifrucht shouldn't the encryption be tls?

luceos

luceos http://blog.mailgun.com/25-465-587-what-port-should-i-use/

Kakifrucht

luceos So what should I put in the mail_encryption field? If I set TLS or SSL/TLS it doesn't work.

luceos

Kakifrucht what port do you use?

Kakifrucht

luceos 587

luceos

Port 587:
This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

All Mailgun customers should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Kakifrucht

luceos When I set the encryption to TLS it won't work anymore.

luceos

Check in the MailGun panel of your domain under Security Settings For Outgoing Mail that Certificate Verification is not required assuming your domain has no SSL certificate running.

same issue here, am using port 25 still same error "can't connect to smtp.mailgun.org"

BlackSheep

A bit of search maybe ? https://discuss.flarum.org/d/2315-mailgun-configuration

PranavJadhav

BlackSheep thanks but i tried every possible option from mailgun, diff ports new mail account. Im on digital ocean so hopefully they don't block any prblm and error is Swift_TransportException: Connection could not be established with host smtp.mailgun.org [Connection timed out #110] in file /var/www/flarum/techflux.me/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php on line 268 Stack trace:

luceos

PranavJadhav your hoster might be blocking the port, try an alternative one or contact your hosting provider.

PranavJadhav

luceos im using digital ocean they dont block any port, i've mentioned please help

luceos

PranavJadhav post your settings (without the password) here please.

PranavJadhav

luceos

i've also tried diff ports and even ssl encryption

luceos

I still think digital ocean is blocking the port, contact support. Your settings are correct.

PranavJadhav

luceos i tried with 3 diff droplets and 2 accounts i dont think so they are blocking all of my ports
