MailDroid caches the headers of an email as it arrives, but leaves it up to the user on what to do about the body of the email. The "Pre-Loading and Indexing Settings" preferences allows you to define per account caching and search support. Please read this carefully so that you can make the correct decision on what you would like to do per account.

MailDroid stores this information on your SD Card and an SD card is required for this functionality. Although the size of MailDroid may go up because of this storage, you can feel comfortable knowing that all this info is on your SD card. Please be aware that Android does not support folder security on anything that is stored on your SD card.

Accounts Dropdown Don't save mail text Save and Index opened mail text Pre-Load and Index all listed messages

The action button allows you to index and get the body for all emails that you have listed (all email headers on your device for that specific account in the dropdown).

Pre-Load and Index Button Possible scenario: Do not pre-load messages older than XX days

This gives you the option not to index messages older than a number of days even when clicked on.

E.g. if set to 2 days and you click some message that was sent to you 3 days ago, it will not be indexed.

To summarize, these settings allow complete control on what MailDroid will do for indexing and caching per email account that is set up.

In the future, more options may be added to this feature.
