Hello,
I am using the latest versions of WP, gravity forms, and wp mail smtp.
I have not been able to get any mail through the website to my client, who hosts their email with Yahoo Business. I installed this plugin hoping it would solve the problem, and I can send emails fine to every account I test, except for accounts at Yahoo Business - I have even gotten success with a yahoo.com email.
When I send a test to my client's email, I get this error:
SMTP -> FROM SERVER:250 OK
SMTP -> FROM SERVER:550 No Such User Here
SMTP -> ERROR: RCPT not accepted from server: 550 No Such User Here
SMTP Error: The following recipients failed: [client's email address]
My client can receive regular email just fine - their email account is set up and working - but they cannot receive any email through their website.
Any help would be awesome - Thanks!
