Communication Error [334] – make sure the Envelope From Email is the same account used to create the Client ID.
This is almost always caused by being logged in to Google/Microsoft/Yahoo with a different user than the one Post is configured to send mail with. Logout and try again with the correct user
Login to Webmail and see if there is an “Unusual Activity” warning waiting for your attention

If you use a custom domain name for email, add an SPF record to your DNS zone file. The SPF is specific to your email provider, for example Google
If you use a custom domain name for email, add a DKIM record to your DNS zone file and upload your Domain Key (a digital signature) to, for example Google
