Hi compakia,

XAMPP doesn't come with a mailserver. That means that you will have to use SMTP. You can do so by configuring XAMPP, espacially the php.ini where you find:

[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25

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

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
;sendmail_path = "\xampplite\sendmail\sendmail.exe -t"

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
;mail.force_extra_parameters =

Do a Google search for the details.

B2evolution will provide a full SMTP solution in the future. From the first tests I wrote a [url=http://forums.b2evolution.net/viewtopic.php?t=14205]HOWTO[/url] to add Swiftmailer to the installation. This works very good.

So, with either solution you should be able to send mail through SMTP. If you have subsequent questions, you can always report back to this tlopic.

Good luck
