smtpgmailcom

smtpgmailcom is a term that appears to refer to Gmail's SMTP service, commonly written as smtp.gmail.com. It may arise from informal shorthand or typos when configuring outbound mail. The Gmail SMTP server is used by clients to send messages through a user’s Gmail account.

To use it, applications connect to smtp.gmail.com with TLS encryption. Typical configurations use port 465 for implicit SSL or port 587 with STARTTLS. Authentication is required, using the user's Gmail address as the login and a password or OAuth 2.0 token as the credential.

Google has deprecated or restricted older authentication methods. For accounts with two-factor authentication, users usually must create an app password or use an OAuth 2.0 flow. In some cases, you may need to unlock the account for new devices via a Display Unlock Captcha page before first connections.

Sending through Gmail is subject to usage limits and policy. Quotas depend on account type (free Gmail vs Google Workspace) and are designed to deter spam. Applications should implement error handling for quota-related responses and comply with Google’s terms of service.
