GYIK

When you get this error when sending mail from your website then it usually means one of these:

• SMTP data is incorrect (double-check username and password, make sure that you specified correct host and port).
• Firewall on your hosting server blocks outgoing connections from specified SMTP host and/or port. Contact your hosting support and describe this problem to fix the issue.
• Specified SMTP host (in case if it is a domain — not IP) is not resolved on your hosting server or resolved to a wrong IP address. Contact your hosting support and describe this problem to fix the issue.

For more details on this issue please refer this page.

The problem may occur when you are using field Form will be sent from this Email in form configuration in builder. For example you use address in this field example@mysite.com. Then mails may not be received on your email account due to the fact that domain mysite.com does not have DNS record of type SPF (for more details please see https://en.wikipedia.org/wiki/Sender_Policy_Framework). Due to this mails can be blocked by mail servers. If you are an owner of domain "mysite.com" you need to add SPF record in DNS configuration of your domain.

When you do not have field "Form will be sent from this Email" filled in then the address no-reply@mysite.com is used (where "mysite.com" is replaced with your website domain name). In this case the reason of not receiving mails is the same as described above.
