Error in sending SMTP email but test email sent successed

Hi Guys,

I have use both Postmam SMTP plugin and WP Mail SMTP both are able to send an test email to me. to set up the SMTP setting too.

I could receive email successfully from contact form 7 only. Have requested my hosting provider to allow SMTP port like 465 and 587.

However, when I used other popular plugin such as ninjaform, WPForm and calderaforms, all failed to send any emails at all.

Below is the error debug log I managed to get from calderaform.

[ErrorInfo] => The following From address failed: example@email.com : MAIL FROM command failed,,,SMTP server error: MAIL FROM command failedSMTP server error: MAIL FROM command failed

            [authenticate] => SMTP Error: Could not authenticate.
            [connect_host] => SMTP Error: Could not connect to SMTP host.

Other info:
Using zoho for SMTP sending email, not gmail or yahoo.
I have tried both TLS and SSL, both will work in testing send email but when actual using other form plugin, it didn’t work again.

LATEST update: still having the same error but able to receive form submission email only via caldera forms plugin.

I’m not sure why am i having such error.

please advise thanks!
