In this case mail_files appears to be an external UNIX command. Probably a script.
You might get very similar functionality using mailx which is available on pretty much every UNIX system.
If -f is supposed to be "From" in the mail_files script then -f probably becomes -r
Likewise if -t is supposed to be "to" it just gets eliminated, mailx assumes an unadorned argument is the "to" address. Mailx will use any text on standard input as the body. So instead of -b you would just write to the stream (the 'PUT STREAM stMail "Email body".' command that you see.) You can attach a file with mailx using -a.

No, I think it's a command line of Thunderbird.
I found this this morning.
