When you select to run a filter manually you can apply the filter to a specific folder. In this case, Thunderbird will change the order, so the reply filter will be executed before the move filter. For example: If you have a filter that moves a message to another folder, and then further down the list a filter that replies, the reply filter will not work because the message is gone from the folder. If you click the link, you will see which order is used. When you archive email - This is when you select Archiving and applies to all mail included in the archive action.įilters are executed in the order they appear in the list of filters, except when that order is not possible, in which case you will see the message Note: Filter actions will be run in a different order, and the link See execution order. These filters only apply to an email being sent. When you send mail - This is when you select After Sending. If you have difficulty with filtering the message body, select after classification. This can occur either before Thunderbird does its assessment of the mail as junk, or after. Filters are applied to new mail in the inbox.

When you receive new mail - This is when Getting New Mail is selected (the default).
