This note relates to Windows Live Mail version 2009 (Build 14.0.8117.0416) running in Windows XP.
I found it impossible to export or copy ‘n’ paste the Safe Senders the addresses from Tools->Safety Options in my Windows Live Mail. I wanted to do this to import the list to the server-based Junk Mail filter provided by my email host.
A bit of digging about in the registry exposed the location of the Safe Senders list as
[HKEY_CURRENT_USER\Software\Microsoft\Windows Live Mail\PerPassportSettings\0\Junk Mail\Safe Senders List]
Unfortunately each address is saved in a separate registry subkey, so a bit of text manipulation is required after exporting the above Registry key to a .REG file. I used Edit-Plus to sort the file, strip out the non-pertinent stuff and perform a find-and-replace on the lines containing the email addresses, which are of the format
"Exception"="goodfriend@gmail.com"
