Frequently Asked Questions
Common questions about Holographic SMTP Helper
No. The setup score and error help are built into the plugin. HoloSMTP uses local rules, saved settings, server checks and saved SMTP errors. SMTP credentials and email logs are not sent to an AI service.
Yes. The Setup Wizard can check public provider setup records and DNS mail records for the email domain you enter. This can find the SMTP host, port, encryption setting, username pattern and likely provider when the provider publishes usable information. Discovery does not find, ask for or test your private password. You still enter the correct mailbox password, app password or SMTP key yourself.
Often, yes. For normal SMTP username and password login, Gmail and Google Workspace commonly need a Google app password instead of the normal account password. App passwords normally require two-step verification, and some Google Workspace administrators disable them.
Yes. HoloSMTP can recognise common SMTP errors such as rejected logins, missing app passwords, blocked ports, TLS or SSL mismatch, sender rejection, DNS authentication problems, provider sending limits and rejected recipients.
No. It works with the normal WordPress mail system, so plugins that use wp_mail() continue to send through the normal WordPress flow.
No. The saved password is not shown on the settings screen. Leaving the password field blank keeps the existing saved password.
Only if you turn on email content logging. By default, the log stores delivery details and errors without saving the email body.
Yes. You can delete one log, delete matching logs, delete all logs, or set automatic log retention.
No. Holographic SMTP Helper is an admin and email delivery plugin. It does not load public front-end scripts.
Running more than one SMTP plugin is not recommended. HoloSMTP warns you when it detects common active SMTP plugins.
