Type: string
Default: none
This specifies the file into which your outgoing messages should be appended. (This is meant as the primary method for saving a copy of your messages, but another way to do this is using the my_hdr command to create a Bcc: field with your email address in it.)
The value of $record is overridden by the $force_name and $save_name variables, and the fcc-hook command.
