I'm tryin to configure the forums reply email notification but it doesn't work.  I configure the password reminder funcionality via web.config  mailSettings and it works fine. I would like to know what else is needed to configure in order to have working forums in the same way.  The error log show the following message:

2009-10-06 22:18:06,634 ERROR mojoPortal.Net.Email - error sending email to admin@mydomain.com, message was: juan<br />juanmadiaz.net@gmail.com<br /><br /><p>Información de contacto.</p><br /><br />HTTP_USER_AGENT: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)<br />REMOTE_HOST: 190.156.122.248<br />REMOTE_ADDR: 190.156.122.248<br />LOCAL_ADDR: 67.228.228.83<br />

I guess application is trying to connect to  127.0.0.1:25 in order to send email. If this is the problem, how can I configure another ip address?

Thanks in advanced.
