Hello there Playerxy We have read your message. We try to help you. There is the automatic answer reply.(oof) there are also methods to have an automatic response returned, this is called an '''out of office method''' which means that you have to leave your pc on all the time. better try to follow the indicated method and use it if it works as desired. it is desirable to deal with fiters within Thunderbird. '''In Thunderbird.''' You would need to create a Template email and store in the Templates folder. Leave the TO field empty. Subject: Out of Office. You would then need to create a message filter which filters after junk classification and checks that each incoming email address is in your address books. https://support.mozilla.org/en-US/kb/organize-your-messages-using-filters#w_create-a-new-filter This prevents you replying to junk and selects only people in the address books. ''If the condition is set'' then perform the action to 'Reply with Template' and select the template you created. Greetings Firefox volunteer.
