BLAT is a command-line eMailer. I use it within a script or command file to send a notification eMail.
With BLAT you can do things like:
C:> BLAT myfile.txt -to email@example.com
The above command sends the contents of the file “myfile.txt” to the eMail address firstname.lastname@example.org.
BLAT stores some parameters in the Windows registry, or in a text file. BLAT needs to know a legal eMail POP account which is used as the “from” address, and a legal SMTP mail account to use to actually send the message.
You can run BLAT interactively, or run it as part of a command file.
