Apple fixed some issues in 10.4 concerning the fax functionality. However, one problem is still not resolved: you want received faxes to be mailed to an email account. This only works if you work inside a network enviroment with host names and domain names, and run your own mailserver. Otherwise the fax appears to come from FaxNotify@your.machine, and many ISPs will reject such mail as it comes from an invalid address.
FaxEmailHelper was a great solution for Panther. The current version does not work with Tiger, though. But if you want the fax-to-email-feature, there is an easy way that worked for me. You have to have the Developer Tools (XCode) installed. Here's how:
- Duplicate (copy) the file com.apple.print.FaxPrefs.plist" in the top-level /Library/Preferences folder as a backup -- just in case you screw up.
- Open the software Property List Editor (in /Developer -> Applications -> Utilities).
- Open the file "com.apple.print.FaxPrefs.plist" after backing it up in step one.
- Hit "New Sibling" to add the line EmailSender of type String with name@mailserver.com as the value, and it should be the email adresss you send mail from.
- Hit "New Sibling" to add the line SMTP of type String with smtp.mailserver.com as the value, and it should be set to your SMTP server address.
- Hit "New Sibling" to add the line smtpAuthorization of type String and a value of Password -- important: type Password and not your actual password. The last line is needed if your ISP wants you to authenticate before sending.
- Save the file, quit the editor, and then check "Receive Fax" option in the Print&Fax section of System Preferences, and make sure you've enabled the Email to option as well.
