Email delivery issues from website

twigggs

I have a client website (wordpress/woocommerce) hosted on blacknight. My client's email is hosted on Gmail and the DNS records on the blacknight host are configured to allow that server send emails on behalf of the domain.


On testing I noticed, sending emails from the site (order confirmation) to -


gmail - All good - delivered to inbox
hotmail / outlook - ok - delivered to spam folder
yahoo - total fail - mail not delivered at all




Here is what I got back from blacknight support -



It is likely that Hotmail/Outlook.com may have your domain - or our servers, on a Blacklist and can be a result of other recipients marking emails as junk (on that system) in the past.

The configuration is fine - there is no issue there.

The only alternative is to send directly via Gmail servers but you will still be subject to the same issues overall


I will say that Yahoo are far too strict on this process as a whole; we have had reports of the same.




It's not an ideal answer to be bringing back to my client that their customer may or may not be getting order confirmation emails.


The blacknight reply indicates that something like this is unlikely to make a difference -


WP Mail SMTP (the pro version) - https://wpmailsmtp.com/pricing-lite/



I have a yahoo mail account and never have an issue getting order confirmation emails so surely there has to be a work around.

Any help much appreciated

Yahoo's outcome would suggest that your server is blacklisted, it appears that they are dropping the incoming email and not wasting any CPU cycles on processing it.

Have you tried any services that will score you email server?

If you are encountering problems with MS managed services then it would be worth your while assessing the reputation of your email server in their eyes.

Google offer a similar facility which you should avail of to ensure everything is configured properly on your part.

Check the server and DNS configuration:

If the IP address is blacklisted then there is little you can do other than change the server used to send email.
