Question

I’ve been using AWS SES with a CakePHP app for a few months, everything was working fine but we had a server problem meaning I had take the site off and get the server restored. Once I put the site back on I noticed emails wouldn’t send and causing CakePHP to error.

The Error

2013-01-14 14:50:02 Error: [SocketException] SMTP Error: 535 Incorrect authentication data
#0 /public_html/lib/Cake/Network/Email/SmtpTransport.php(132): SmtpTransport->_smtpSend('QWhRZ2F0azQyTnh...', '235')
#1 /public_html/lib/Cake/Network/Email/SmtpTransport.php(61): SmtpTransport->_auth()
#2 /public_html/lib/Cake/Network/Email/CakeEmail.php(1059): SmtpTransport->send(Object(CakeEmail))
#3 /public_html/app/Controller/UsersController.php(1945): CakeEmail->send()

What I’ve done so far

1. I’ve checked both the domain and email are verified.

2. I regenerated new SMTP details just incase they where wrong.

3. Made sure my server time was correct using NTP

4. In the meantime I set up SMTP with a google business apps.

My Configuration (Some details altered for security)

public $smtp = array(
'transport' => 'Smtp',
'from' => array('[e-mail]' => 'Company'),
'host' => 'ssl://email-smtp.us-east-1.amazonaws.com',
'port' => 465,
'timeout' => 10,
'username' => 'AKIAICH5321NNDR2CMA',
'password' => 'AhQgat12Nx21c5e78S9Ufku0+4fw9LnRpuMTGZwjXT',
'client' => null,
'log' => false,
);

My Configuration for Google Business Apps (which works)

public $smtp = array(
    'transport' => 'Smtp',
    'from' => array('[e-mail]' => 'Company'),
    'host' => 'ssl://smtp.gmail.com',
    'port' => 465,
    'timeout' => 10,
    'username' => '[e-mail]',
    'password' => 'b1t306b',
    'client' => null,
    'log' => false
);

Could I be missing some module of my server or has AWS changed something that happened round the same time as my server change? I’d really appreciate any help or advice. Thanks Jason

Answer 1

I’ve found the issue. Under WHM there is an option SMTP Restrictions, I disabled it.
