Hi there @cw1210,

Thanks for reaching out! According to the error message, the SMTP server you’re connecting to is rejecting the email because it thinks it contains spam content. Basically, your email is triggering their spam filters, and they are refusing to send it. You could try contacting your SMTP provider about it to find out what rule you might be triggering. It may be a getting misflagged, or there may be part of your email that needs to be changed.

Additionally, you can try sending through another mailer service. Check out this guide in our documentation. It walks through each mailer we support and includes the benefits of each: https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/

I hope that helps! Have a great day!

Hi there @hemant112233,

I do apologize for the delay.

If your site is being targeted by spam bots, captchas can usually help. However, it is important to note how captchas work. They are intended to prevent a spam bot from submitting a form. When they work, any data the spammer tries to send will never reach WP Mail SMTP because it will be stopped at the form level.

If spam is getting through, it means the spammer is either sending the spam through some other method (perhaps another form), or they are getting through the captcha. Depending on the type of captcha you are using, this could be possible, as some captchas are much easier to avoid than others.

Try sending a test email using only WP Mail SMTP. You can use the Email Test feature in the Tools section. If that email gets through, it means the issue is likely on the form or captcha side of things.

However, if the Email Test from within WP Mail SMTP does not go through, try redoing your connection to Outlook, specifically the SMTP Password. Microsoft requires the use of App Passwords for SMTP connections, so you won’t be able to use your regular Outlook password. Instead, you’ll need to create an App Password to connect with.

We have details on how to create one here: https://wpmailsmtp.com/docs/how-to-set-up-the-other-smtp-mailer-in-wp-mail-smtp/#secure-outlook

Also, you can check your Outlook account’s Sent folder to see if emails are showing there. If they are, it means they at least made it to Outlook.

Regarding the error message you originally posted, you would need to check with Outlook to find out more about it, or install a logging plugin like WP Mail Logging to capture a copy of the email that was sent when the error occurs. There would be something about that email that Outlook isn’t accepting, and given the custom code and the spam bots, it could be either one.

I hope that helps! Have a great day!

Hi there @kabarovsky,

Thanks for reaching out. This happens because you’re sending through your Gmail account, so Gmail puts a copy in your Sent folder. Outlook does the same thing. We’re unable to change that behaviour since it’s handled on the mailer side of things.

I hope that helps! Have a great day!

Hey there @rkra,

It sounds like the translations may not have downloaded for you. When you get a moment, check your updates to see if you have any translations updates available.

I hope that helps! Have a great day!
