problem sending mail from command line/script

["Matt Van Mater" <nutter__(_at_)_hotmail_(_dot_)_com>]

I want to be able to check my IP every few minutes from cron and if my IP 
address has changed I want to send an email to a hotmail account notifying 
me of the change.  (eventually I want to automatically reset my NAT and 
restart pf with the new settings, but that is the next goal)  I have the 
script all set up that identifies the current IP and compares it with the 
old one, but I can't seem to get the command line util 'mail' to send the 
message.  I always get an error message saying:

root... Connecting to localhost.mydomain.com. via relay...
root... Deferred: Connection refused by localhost.mydomain.com.

where 'mydomain' is actually my real domain name.  I fairly sure that this 
error message happens because sendmail is configured by default to not be an 
open relay (which is of course a good thing).  How can the default daily 
insecurity output in cron send an email, but my little script can't?  I've 
tried sending the message to the local root account just to see if it had 
anyhting to do with sending the message outside my network, but that doesnt 
seem to make a difference.

I tried searching on the marc but for some reason it doesn't allow the 
keyword 'mail' to be used in a search.  I understand why that might be 
excluded, but how else am I supposed to search the archives for problems 
with the unix command called 'mail' ?  I just thought that was curious.
