I've uploaded a beta version here. It adds a mail action to AutoFiler
<tr><td>mail to</td><td>This allows you to send an email when the rule is applied. You can optionally attach the matching file to the email. Sending emails requires some configuration. The easiest way is to click <b>Edit</b> in the rule editor and borrow the settings from Mail.app. This allows you to use Mail.app as a way to test the validity of your settings. If you use this option, AutoFiler always uses the current settings for that Mail.app account. Otherwise you can select Custom, for your mail account in which case you have to manually enter your From: address, and as well you can select Custom for the SMTP server, in which case you have to enter the hostname, and optionally the username and password for the server.
<br/><br/>
Passwords for SMTP servers are stored in your Keychain for security. When you access the passwords OS-X will bring up a dialogue asking to use your keychain information. It's important that you select <b>Always Allow</b> since AutoFiler will need to access the keychain when it is sending an email in the background, and otherwise it could bring AutoFiler to a halt asking you to reauthorise access.
<br/><br/>
The mail rule will attempt to immediately send the mail through the server. If it fails, the rule will return failure. You could for example, set up your rules to show a Growl message at this point. If you have ticked "Cache when offline", then mail that fails to send on the initial attempt is stored internally for up to 2 weeks, and retried at incremental intervals, similarly to how an SMTP server does it. In this case, if the network is down, the email will go though eventually when you reconnect, provided AutoFiler is running.
<br/><br/>
The special tokens ${FILE} and ${PATH} will be replaced in the subject and body of the message with the filename or full path of the matching file.</td></tr>
