Error Message

An unexpected error occurs while sending mails from website.

Other Information

I’m using a custom php script configured with phpmailer but it’s not working. As of my knowledge infinityfree supports phpmailer only. Here’s my script:

Are you using your login password for Gmail? Or have you set up an app password?

You need to use an app password. In my experience this is the biggest cause of problems

Greenreader9 · April 22, 2025, 2:48pm

Another thing to note is that if all those emails are linked to the same Gmail inbox, Google will only show the email in the sent folder, not your inbox. I would send the email from a separate Gmail inbox, or to a different inbox.

Is this the actual error message you see? Because the script looks custom, so I would expect that you could get a more informative error message from your software. Or maybe set $mail->SMTPDebug to a higher value, like 4, to get a bit more output as to why the connection fails?

But like @dan3008 also said: the most likely reason to me seems that you are trying to login with your Google account password, which is no longer supported. You have to enable 2FA on your Google account and then create an App-Specific Password to use SMTP.

webhost · April 22, 2025, 3:27pm

@dan3008 I’m using App password

webhost · April 22, 2025, 3:29pm

no I’m using app password only

webhost · April 22, 2025, 3:33pm

@Greenreader9 My receiver mail id ‘’‘[email protected]’‘’ is hosted on zoho, and I’m using SMTP of my gmail account [email protected] both are not same inbox

webhost · April 22, 2025, 3:38pm

@Admin I have tried with changed value of 4 for SMTPDebug but still getting the same error

Admin · April 22, 2025, 7:55pm

Have you tried anything else to get a more useful error message? Or maybe even set the SMTP debug log even higher to try and get more output?

Gmail may require login. Why not use mail function of php, much simpler and easier to customize.

dan3008 · April 23, 2025, 8:54am

the PHP function mail() is blocked on the free hosting unfortunaitly.
