Disable automatically saving sent email addresses to address book

Automatically saving contacts from sent outgoing emails can raise several privacy concerns:

1. Unintended Data Collection: Users may not be aware that their email client is automatically saving email addresses. This can lead to the collection of contacts that the user may not want to keep, such as one-time correspondences or addresses from spam.

2. Exposure of Sensitive Information: If the email client saves addresses from sensitive communications (e.g., confidential discussions, political activistm or whistle-blowing, and personal matters), it could lead to unintentional exposure of that information if the address book is accessed by others or if the account is compromised.

3. Lack of User Control: Automatic saving removes the user's control over what information is stored. Users may prefer to curate their contacts manually to ensure that only relevant and trusted contacts are saved.
