Closure of port 25 | How to modify the port in Android

Due to a security update, port 25 has been disabled for sending emails.

Additionally, the authentication system has been unified, so it is now necessary to use a normal password along with a secure connection.

New required configuration
For email sending to work correctly on Android, you must configure:
  1. SMTP Port: 587 or 465
  2. Security: STARTTLS (587) or SSL/TLS (465)
  3. Authentication: enabled
  4. Password: normal (not manually encrypted)
How to change the outgoing port on Android
  1. Open the email app
  2. Go to Settings > select your account
  3. Access Outgoing server (SMTP)
  4. Modify:
    1. Port: 587
    2. Security: STARTTLS or TLS
    3. Authentication: enabled
  5. Save the changes
Common issues
  1. If you cannot send emails, check that port 25 is not configured and that Android saves the changes correctly.
  2. Verify that SMTP authentication is enabled
  3. Make sure you are using the correct password (without old encryption settings)
