My notifications on subscriber and welcome emails are working find they are been received it is The WordPress latest post not sending as scheduled.

The history shows not sent

Any ideas why this is

I authenticate SMTP via Yandex Mail service. Test email works fine and receiving. Once I receive the test mail, I can see an error as below.

EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.6.0 logged this error during the last time it tried to send an email:

Mailer: Other SMTP
SMTP Error: data not accepted.
Consider running an email test after fixing it.

Whether I received the test email, I can rarely submit a form. Most of the time I can’t submit the email at least. Most of the time I am getting this error.

There was an error trying to send your message. Please try again later.

I am using Contact Form 7 for forms.

Expect your prompt support on this.

Thanks in advance

“If your contact from 7 plugin treat a form submissions as spam and it failed. Add the following line in your functions.php file

add_filter(‘wpcf7_spam’, ‘__return_false’);

I put this line in the functions.php and it started working again. But it took 3 hours to find this solution. (Faster than the “support” reply though.

I write here if you’re having the same issue with it. I don’t know why this happens but it is ridicilous. My other website with same plugins work fine. This might be a bug, I don’t know. I don’t know what is the disadvantages to put this line in the functions.php but it started to work properly. I think I will use another plugin for my contact form because I don’t trust these kinds of modifications even if it solved the problem.

• Mailgun
• WooCommerce
• WooCommerce PDF Invoices & Packing Slips
• WP Mail Logging (debugging purposes)

Then neither my automated nor triggered Woocommerce Order emails with attachments go through. WP Mail Logging gives me the error: “Invalid address (setFrom) [email protected]” [Obviously, the actual address is valid.]

I have the plugin set to attach invoices to: New Order (admin email), Processing order, Completed Order, Refunded order, Customer invoice / Order details (manual email). None of these work. HOWEVER, Customer note (which is not selected) does still work. This seems to be a plugin conflict between you and Mailgun.

Any ideas?

Can anybody help me?
