Shell Programming and Scripting

Is there any way that I can mailx to a distribution list without having a $HOME/.mailrc file?
We have a distribution list in Outlook for our group say group@something.com.
I am trting to do echo "Something"|mailx -s "Subject" group@something.com
it doesnt work
Any ideas?
Thanks

First, what OS and version? Second, what error do you get?

Third, is the box/system/server you are running this command from part of the something.com domain? If so, it may be that when you run the command, it looks runs through the rules (assuming Sendmail) and finds that it is part of that domain, strips it, and then goes looking for 'group'. If it has no clue what 'group' is, then it can do one of two things - it will either send it to where the rules state to send mail it has no clue what to do with OR it will error and send a error message back to the sender. Either way, you should see an email. You may have to either set up the box/system/server you are running the command on to forward any emails it doesn't know what to do with, or set up an alias which sends it to the group of people you want to send to.
