Answer 1

For laravel >= 7 And you are getting this error :

Connection could not be established with host smtp.sendgrid.net :stream_socket_client(): unable to connect to tcp://smtp.sendgrid.net:587 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Simply update your .env file From:

MAIL_MAILER=smtp
MAIL_DRIVER=smtp
MAIL_HOST=smtp.sendgrid.net
MAIL_PORT=587
MAIL_USERNAME=apikey
MAIL_PASSWORD=your_sendgrid_api_key
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME="Your Sender Name"
[email protected]

To:

MAIL_MAILER=sendMail
MAIL_DRIVER=sendMail
MAIL_HOST=smtp.sendgrid.net
MAIL_PORT=587
MAIL_USERNAME=apikey
MAIL_PASSWORD=your_sendgrid_api_key
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME="Your Sender Name"
[email protected]

Then run this command to make sure .env changes is sync with the code.

php artisan config:cache

Answer 2

Update your env file to:

MAIL_MAILER=sendmail
MAIL_HOST=smtp.sendgrid.net
MAIL_PORT=587
MAIL_USERNAME=apikey
MAIL_PASSWORD=apiPassword
MAIL_ENCRYPTION=tls
[email protected]
MAIL_FROM_NAME="${APP_NAME}"

Also in your Laravel project under the config folder look for

mail.php

and make changes as follows:

'default' => env('MAIL_MAILER', 'sendmail'),

N/B: SMTP works on localhost and sendmail works on live server.
