Troubleshooting

Test email fails

Double-check the server name matches the one in your mySMTP setup email exactly. Verify the username and password are correct. See Common SMTP errors.

Connection timeout on port 587

Your upstream firewall or ISP may block outbound port 587. Try port 2525.

Authentication rejected

Confirm the authentication mechanism is set to PLAIN or LOGIN (not OAuth or NTLM). Re-enter the username and password carefully.

Sender address rejected

Make sure the sender address uses a domain authenticated for your mySMTP account. See DNS settings quick explainer.
