How do I save a copy of outgoing mail?

Two methods:

1. (setq mail-self-blind t) will result in a `BCC:' header line with your address being added to mail composition buffers. This will cause the mail system to send a copy of the mail back to you.
2. (setq mail-archive-file-name (expand-file-name "~/outgoing")) will result in an `FCC:' header line with the pathname of ~/outgoing being added to mail composition buffers. When you send the mail, Emacs will save a copy of the mail in the file ~/outgoing and then strip off the `FCC:' line before actually sending. WARNING: There is a bug in Emacs 18.58 that prevents mail readers such as RMAIL from reading the saved mail messages individually. See section Why does RMAIL think all my saved messages are one big message?. WARNING: If you are visiting the file ~/outgoing at the time you send the mail, this can cause a variety of horrible problems. Jamie Zawinski has written a solution for this.

It does not work to put `set record filename' in the .mailrc file.
