My TXT record is "v=spf1 ip4:ipaddress include:spf.google.com ~all". But what is the value to be added to TTL field? Is it 3600 or 1800?
And my Laravel 5.4 project's .env looks:
But it doesn't send email out and generate: Connection could not be established with host smtp.gmail.com [Connection timed out #110]
