Email Setup Finder

Enter an email address or domain to look up IMAP, POP and SMTP settings — host, port, encryption and username. We check known provider settings, Mozilla's provider database and DNS mail records. Unconfirmed settings are clearly marked for verification with your provider.

Tip: the username is usually your full email address. Microsoft 365 requires a compatible modern (OAuth2) sign-in. Gmail may use OAuth2 or a provider-generated app password, depending on the account and client.

Chasing an email delivery or spam problem instead? Use the DNS & Email Checker for live MX, SPF, DKIM, DMARC and DNSSEC, or the Email Header Analyzer to trace a message's path.
