Hi Gochi
You need to add the email configuration options to your config_inc.php file.
See the manual at
http://www.mantisbt.org/manual/manual.c ... .email.php
for details of how to do this.
Also look through these forums, as help on configuring email is a common topic.
If this is a local test server, you can use MercuryMail from the xampp installation as
your mail server.
If you have further problems with this, could you post the relevant details from your
config_inc.php file (with userids and passwords etc removed of course).
You should be able to connect to mantisbt on your local machine from other machines
on your local network.
You may need to change the firewall settings (if enabled) on your pc to do this.
If you have problems connecting to your pc from another machine when it is running xampp,
I would suggest using the xammp support forums at
