By default, the application tries to send messages and if it fails, it resends them 1 hour later.
You can tell it how many times it should retry.
- Click "Options" toolbar button.
- Enter a number of retries into the "Retries" text box.
- Click "OK".
Note: Regardless of the settings, the program will try to send every message at least once before it sees if the message should expire.
