EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.4.0 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.
I am now getting this error whenever I use our web forms.
This only happened about 24 hours ago.
“Other SMTP” option
SMTP Host: smtp.bizmail.yahoo.com
Before yesterday, the forms are working perfectly. We did not changed anything before the issue happened.
