My bugzilla system keep hit the following error:

There was an error sending mail from '[email protected]' to '[email protected]':Can't send data

I think that is some problem with my setting and configuration.

1. First is the urlbase

   I have tried setting it to bugzilla.example.com, and http://127.0.0.1:81/, and http://10.0.0.236/ (My laptop IP address, I use this laptop to set up bugzilla) but the error still persists. Actually what should I put in the urlbase field?

2. Parameter => Email

   Under mail_delivery_method, i choose SMTP.

   Under mailfrom, I put bugzilla-daemon.

   smtpserver, I tried leaving it blank, or setting it to 220.181.12.12 before, but could not solve my problem

3. For my sql, the following is the data and command I used:

   C:\mysql\bin>mysql --user=root -p mysql
   
   
   Enter password: 1234  (When I install mysql into my laptop, it ask me to key an username and password, i have key in username as 'cvuser' and password as '1234', but here never ask me to key in any username)
   Welcome to the MySQL monitor.  Commands end with ; or \g.
   Your MySQL connection id is 1
   Server version: 5.5.15 MySQL Community Server (GPL)
   
   mysql> GRANT ALL PRIVILEGES ON bugs.* TO 'bugs'@'localhost' IDENTIFIED BY '123456';
   Query OK, 0 rows affected (0.03 sec)
   

4. In C:\Bugzilla\localconfig, I put the following info:

   #
   # How to access the SQL database:
   #
   $db_host = "localhost";         # where is the database?
   $db_port = 3306;                # which port to use
   $db_name = "bugs";              # name of the MySQL database
   $db_user = "bugs";              # user to attach to the MySQL database
   
   #
   # Enter your database password here. It's normally advisable to specify
   # a password for your bugzilla database user.
   # If you use apostrophe (') or a backslash (\) in your password, you'll
   # need to escape it by preceding it with a \ character. (\') or (\\)
   #
   $db_pass = '123456';
   

Can someone tell me where my mistake is? I have googled for this issue for few days but still cannot find the solution.
