For some reason my mail SMTP is not working

Kayo

Hi guys, idk if that's the right tag but let's go.

I'm trying to use mailgun for my server, but when i put info requested on my host domain settings, didn't work.

Thats the info they passed to me:

(TXT)
mg.mydomain.com -> value: v=spf1 include:mailgun.org _all

(TXT)
mx._domainkey.mg.mydomain.com -> value: k=rsa; p="there's a key here"

(MX)
mg.mydomain.com -> Priority: 10 -> value: mxa.mailgun.org
mg.mydomain.com -> Priority: 10 -> value: mxb.mailgun.org

(CNAME)
email.mg.mydomain.com -> value: mailgun.org

anyone knows a tip about that? i host the site on gCloud and my domain is from hostinger

Kayo those will be for your DNS settings - they won't work in flarum. The settings they have provided are designed to reduce the probability of your email being classed as spam.

It looks like

email.mg.mydomain.com
Will be your relay host for use in flarum

[deleted] Yeah, i put those on DNS zone on the fields betwenn (""), but returns on mailgun that the DNS didn't propagate, returns: "none found"

Kayo you entered them at your host, yes ? DNS can take up to 48 hours to fully populate, so it's highly likely that the changes haven't made it to mailgun yet.

[deleted] oh, i thought was 24h, so i will wait another day, thank u

Kayo you can check progress here
https://dnschecker.org

Note that SPF and DKIM entries etc are very specific and a simple mistake means it won't propagate

[deleted] wow, didn't know that, thank u. I put domain and check MX and show only a lot of red x's, gonna wait a little more.

Just another doubt, i put my domain with cloudflare SSL, should i configure the zone on cloudflare or hostinger? The tutorials about that are só weirdly confuse 🙁

And there's a way i use a simple mail line .gmail.com or .outlook.com instead SMTP for a while?

Kayo if you're running via cloudflare, then there's a high chance that your DNS is via them also (otherwise traffic won't flow through them). If you check the name servers for your domain, you can tell if cloudflare is hosting your DNS or not. If they are, the name servers should be

Joan.ns.cloudflare.com
Noah.ns.cloudflare.com

If they are set to something else, then your DNS in hosted elsewhere. If the former, make the changes in cloudflare DNS and set to TTL to something like like 5 minutes. It'll propagate quicker with a smaller TTL.

[deleted] was cloudflare!!!! Haha, theres a field there to configure zone DNS from their secure network. I put all info there and the mailgun recognized in minutes. I feel happy but sad at same time because was solved but was really simple.

This possibly adds nothing to the expert answers by @[deleted], but what I noted while scanning this thread:

DNS officially takes 24 hours to delegate, but rarely does. New values most often evaluate within a few hours, unless you have set your TTL disgustingly high 😉

If you want to check your dns locally and have a terminal:

$ dig ns luceos.com

The nameservers listed are responsible for serving the correct DNS records.

luceos that's correct. In most cases, it's a couple of hours, but there are some hosts that require manual acceptance (although they are quite rare) and changes over a weekend often don't show up as complete until Monday morning. Been there, done that 😁

Mxtoolbox also has a great array of tools to ensure you get the DKIM and SPF records right. Nothing worse than entering a record and finding out it didn't populate because of a mistake - which several BIND based servers will discard.

Kayo it's always the simple stuff that gets you. Glad you got it figured out.
