Re: batch mode to send email; bug in "mail"

[ken]

Trying to get emacs to send an email in batch mode.
Using this code:

(setq send-mail-function 'smtpmail-send-it
      smtpmail-smtp-server "mail.server.tld")

(setq mail-default-headers
      "X-goal: Trying to send Mail with elisp\n")

(mail nil "address@hidden" "my favorite subject")

(insert "Blah, blah, blah.\n")

(mail-send-and-exit)


The error I get is with the third line-- "(mail nil ...)":

Wrong number of arguments: #[(arg)
("/usr/share/emacs/21.3/lisp/mail/sendmail.elc" . 21146) nil 2
("/usr/share/emacs/21.3/lisp/mail/sendmail.elc" . 20985) "P"], 0

(Error is all on one line, of course.  My mail client autowraps.)

Note that there's no error when I put the point after the line in
question and do "C-x C-e" but only within an .el file executed from bash.

I comment out  the line ''(mail nil ....)'' and the error goes away.

"C-h f mail" says there can be more args, but doesn't say it must.
