Does anyone figured out the solutions for this issue. I believe most of the plugin user who enabled SMTP are getting this issues. Please let me know if someone has solutions for it.
same with me the problem is the plugin contact form is sending emails using phpmail, which can send only from your hostname server and not from mailboxes on your own domain for example admin@domain.com. i also got the same problem witn sendgrid. now i can use only the woo plugin with gmail
