When see this error,
Expected response code 250 but got code “”, with message “”
Please triple check your email password.
Note :
Test your credentals first on a phone app or log-in into the mail site.
If pass, you may update in your .env file
MAIL_DRIVER=smtp
MAIL_HOST=smtp.mail.yahoo.com
MAIL_PORT=465
MAIL_USERNAME=dev.bheng#yahoo.com
MAIL_PASSWORD=****
If you know for sure that your password is correct.
Check to make sure your Gmail or Yahoo Mail allow app log-in.
Example
Yahoo

we solved this problem by clearing the Laravel's configuration cache
php artisan config:clear

Answer 3

looks like the smtp was blocked for hostinger free users.

Answer 4

This one worked for me, 'if you are using GMAIL'
Go to 'My Accounts'
Go to 'Sign-in & security'
Scroll down to 'Allow less secure apps'
Switch #3 to ON
After doing this and if you just recently set up your email configurations on laravel and still doesn't work, try running:
php artisan config:cache

Answer 5

I've a working laravel swiftmailer using google server. Here my steps:
I visited the link
https://www.google.com/settings/security/lesssecureapps and turned
on less secure apps.
I edited .env file as like below:
MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=username //i.e. username#gmail.com
MAIL_PASSWORD=password //Gmail accounts password
MAIL_ENCRYPTION=ssl
Edit username and password with your own.
In my controller, I wrote the following code:
$rawData = request::all();
Mail::queue('program.meeting.emailInvite', $rawData, function($message) use ($rawData)
{
$message->from('info#echosofts.com', 'Echosofts')->to(array_map('trim', explode(',', $rawData['all_email_id'])))->subject($rawData['mail_title']);
});
Then email was working fine except the sender email ID was my google account (username#gmail.com) instead of info#echosofts.com.
To overcome the sender email changing problem, I visited my google account and did the following:
"Setting icon"-> Settings -> Accounts and Import->Send mail as->Add another email address your own.
The following settings depends on your configuration.
Email address: info#echosofts.com
SMTP server: mail.echosofts.com
Username: info#echosofts.com
password:**********
Port:25

FWIW - I get this error when sending a email with an empty string in the to field.

Answer 7

in "mautic" (CRM), if you mail to a large amount of contacts, like more than 10k this occurs. The real reason is mostly a wrong configuration in php settings. For example:
max_input_time = 60
Will only let your server run the script for 60 seconds, try a higher value.
PHP configuration depends on your server and its installed software, mostly configured by htaccess or php.ini file.
