WHMCS not sending emails

[jubba890]

I opened a ticket with WHMCS's support and they said it was my mail host. I then opened a ticket with my mail host and they said it was WHMCS's support. Long story short, they are blaming each other and at this point, no help to me. I have a server which is running at least 10 applications (mail client, WHMCS and other applications that use mail).

 

My WHMCS when I send mail gives me an error: Could not authenticate. I know the username and password is right because I have the mailbox linked up on my phone and it also sends other emails via PHPMailer on my other applications except WHMCS. WHMCS support sent me a PHP file to test if mail would send via PHPMailer in WHMCS and it did. They said the problem was my hostname (It is named Web, and for 8 months I have had the same hostname) I know this is not the problem but they insist that it is. Any help is much appreciated.

 

With SMTP_debug set to true, I get the following error:

Hi,

What error do you get in Utilities > Logs > Activity Log at the time of email sending please?

[jubba890]

12/04/2014 10:57 Email Sending Failed - SMTP Error: Could not authenticate. (User ID: 1 - Subject: Now Accepting Bitcoin!) admin XX.XX.XX.XX

Hi jubba890,

 

What 'SMTP SSL Type' are you using from the WHMCS backend?

 

Have you selected the correct 'SMTP Port' for the 'SMTP SSL Type' you are using in the backend?

 

Do your other applications that send email use the exact same settings as those selected in WHMCS?

 

Also are you running any firewall such as ConfigServerFirewall?

 

Seen as your 'Activity Log' shows you could not be authenticated maybe your Firewall (if you are using on) is blocking ports!

 

Thanks, Ben.

Hello, I copied all the settings to WHMCS and disabled all firewalls, and the port is also correct but it does not work still.
