Hosted Mail: Email Sending Failed - SMTP Error: Could not authenticate

[USAccess]

Hello,

I am using Zoho Mail for hosted email. I need to use SMTP so that DKIM/SPF are used and my emails do not go to spam. I have tried for the last 7 hours and connect get WHMCS to work with SMTP.

 

server: smtp.zoho.com

port: 465

username: account@mydomain.tld

password: mypassword

SMTP SSL Type: SSL

 

 

I know these settings are correct because I have tested them as an SMTP server via GMail and set up the account in Thunderbird to ensure it is all working fine.

 

My log is filled with:

Email Sending Failed - SMTP Error: Could not authenticate. (User ID: 11 - Subject: Your new password for Hosting)

 

Help!

Hi,

The authentication error is being returned by your mail server, so it would be worth checking with your mail server admin on this. To get a more detailed output, add the following to your configuration.php file:

 

$smtp_debug='true';

 

Send an email and you'll get more of the response form your mail server, which should help you debug the issue. Don't forget to remove it afterwards.

I got this problem too,

 

An Error Occurred

SMTP Error: Could not authenticate.

 

How to fix this?

@satsuke - Did you follow the steps outlined previously by John? The first step would be adding the following to your configuration.php file:

 

$smtp_debug='true';

 

That will give you a more detailed error when you attempt to send an email. Depending on that message you may want to talk to your mail server admin if you are 100% certain you are using the correct login details.

 

--Thanks
