(Following notes supplied by Nic Storey, for which, many thanks)
Download Blat and place it in your PP logs file (this is where I have put it).
Open notepad and copy the below lines to it. Note that the blat parameters should all be on one line, or use the continuation character (^) as shown below:
@echo off
blat AlertMessage.txt ^
-server (your SMTP server address) ^
-u (username here) ^
-pw (password here) ^
-t (email address to send too) ^
-f (email address from here )^
-s "PP Alert" -q EXIT
From Notepad, save the file named as PPalert .bat and place in the same directory as Blat.exe.
Then in Plane Plotter, in the Shell alert setup window type: PPalert.bat.
(Question from DJT - should you include the full path to the shell command in that window - I can't find that in the Plane Plotter Help.)
The file AlertMessage.txt is used to send the alerts so if there is not one already in your logs folder just create a .txt file called that. You can double click on PPalert.bat to test it and all being well you should get an email.
Hint To make things it a little easier for some you can also download 'LWBlat GUI' from http://code.google.com/p/lwblat-gui/wiki/Download#32-bit. This is a front-end for Blat and makes setting up the .bat file easier, and it will also allow you to test the command first.
