Google Apps Mail mail Sending Failed - SMTP Error: Could not authenticate.

[Guest dhblewis]

I use WHMCS with google Apps mail and it has been working fine.

 

But today I started getting

mail Sending Failed - SMTP Error: Could not authenticate.

 

I checked all passwords etc and nothing was changed so I don't know what to do?!

This is an issue with the server you are using, nothing to do with WHMCS

Search "authentication error SMTP" on google

There is a setting you need to change when using an external mail client with SMTP server

 

Some of my clients have started reporting this, and now added an article to my Knowledgebase :

 

Tools -> Account

Select the account -> Properties > Server Tab

Under the OutgoingMail Server section check the box My server requires authentication and click the Settings, select Use same settings as my incoming mailserver

He's using google apps to send email from WHMCS, his email client has nothing to do with it.

 

I'd probably check your email server logs to see whats happening. Its possible that google locked the account and you need to reset the password. What settings do you have configured in WHMCS for sending the email?

[Guest dhblewis]

My settings are:

 

SMTP

Port 587

Host smtp@gmail.com

Username mail@mydomain.com

Password mypassword

SSL type TLS

[laszlof]

Try using the following:

 

Port: 465

Host: smtp.googlemail.com

SMTP SSL Type: SSL

[Guest dhblewis]

Got it to work with

 

587

tls

smtp.googlemail.com

[Guest dhblewis]

It's stopped working again even though no passwords were changed.

 

Really beginning to bug me now.

[Guest dhblewis]

Any advice?

[pankaj4learn]

Hi,

These settings work for me here:

 

mail method --> SMTP

PORT 465

host: smtp.gmail.com

Type SSL

I've tried all the above combos and keep getting the same error. Like dhblewis it just stopped working one day for no reason and hasn't come back. Even tried setting up Mandrill but getting the same error.

 

Any ideas?

Did you ever get this working in the end? I'm having the same issue and just can't seem to get it working with any settings. Have even spoken to Google Apps support to confirm the SMTP server settings but still settings the Could not authenticate error.

This problem happens with my 2 WHMCS system.

And i dont have any idea to solve this.

I *HAD* it working the day after I posted on here, then a few days later its buggered up again and I've not been able to fix it.

 

Think i'm going to have to move away from Google Apps as this is just ridiculous.

I agree with you! :-(

Hi everyone, I had this problem, i searching and searching I found no answer, but in my case the problem was the firewall on my local server (CSF) was blocking ports post, so I fixed it as follows form:

 

In the Firewall settings sigueinte find the line:

 

SMTP_PORTS = 25, 465, 587

 

change it

 

SMTP_PORTS = 25

This did it for us - Many thanks!

If you changed the Firewall rules to only allow 25, what did you put as the out going port on WHMCS >> Mail Settings ?

The setting in CSF is actually ports to block and not ports to allow. Hope that clears up the confusion.

THANK YOU !

 

CSF was the culprit

I was facing same problem. Emails were not delivering via Gmail SMTP, I have tested everything CSF was fine, I was able to send emails through SMTP via a WordPress plugin to my WordPress blog hosted on same server but not through WHMCS.

 

I tried everything by disabling CSF, by removing cPanel's smtp restrictions and whatever I can do but it was not working for me. However I just re-write the password again although it was saved already but after doing this it has started working.

Apologies for reviving an old thread, but I too was having all sorts of headache with this. When trying to set up email via whmcs i kept getting the following error: Email Sending Failed - SMTP Error: Could not authenticate.

 

My Hosting provider confirmed that CSF had nothing to do with this and that the ports were not blocked.

 

I eventually contacted google support and they told me to:

-go to admin.google.com,

-then ‘Security (Click 'More Controls' at the bottom if you don't see it).

-next, go to ‘Basic settings.'

-and then Go to ‘Settings for less secure apps.’

-Select the option ‘Enforce access to less secure apps for all users.’

-Save changes.

 

The reason for this is because you’re allowing a non Google product access to your account’s information.

 

Following those steps resolved my issues instantly and the whmcs activity log showed that emails were being sent
