cant change admin password

[Anonymous]

cant change the admin password after install. iget the following:
Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing in c:\documents and settings\.....\my documents\apache\apache\htdocs\rcmax155\hebrew\cat alog\admin\includes\classes\email.php on line 502

any ideas?

in php.ini look for and change if needed:

[mail function]
; For Win32 only.
SMTP = localhost

; For Win32 only.
sendmail_from = me@localhost.com
