Typical Email Error Messages Brad MarkleUpdated on August 16, 2021 2 Minute Read Included with your InMotion Hosting account you have the ability to set up and manage multiple email accounts. Email can be managed using many different email clients such as Thunderbird, Outlook, Mac Mail, and more. You may receive an email message when first configuring your email client or when you check your email. Here are a few of the most common messages: Authentication Errors Incorrect Password When you set up the email account in cPanel for the first time you decide on the initial password for that specific email account. If you don’t remember the password, that’s okay too. As long as you can access cPanel, you can update or change your email account’s password. Please make sure you are using the email account password and not the cPanel password. If you need to change an email account’s password this can be done in the “Email Accounts” section of cPanel. Invalid Username Your username should be your full email address. If your domain is example.com and you have an email account for sales, the username would be [email protected]. Do not use your cPanel username as this will cause an error. Unsecure Connection (or SSL Error) All of our clients on a shared hosting package have access to a shared SSL certificate. You can configure your email client to use that SSL certificate when checking your email. To use the SSL, you will need to change a few settings. You will need to use “secure” instead of mail.example.com. If you have the email client to use the SSL but are not using the corrent mail server such as “secure108.inmotionhosting.com” it will cause a warning “Unsecure Connection” error. 503 valid RCPT Command Must Precede Data If you are getting this message, ensure you have selected “My outgoing server (SMTP) requires authentication” when you setup your email client. Other If you are still getting an error message and you’re not sure about how to resolve the issue, please contact our technical support department. We will be happy to assist you further.
