ok I setup a dummy account to catchall the unknown destination, I do this just so email won't bounce back eating my bandwidth from spammers. But things get worst, the server keep on working on something which I don't have any idea what it is doing, the hard drive lights is always lighted and I can hardly work on anything (my server is a P4 2.66 with 250MB drive), the keyboard response is very sloooow. I suspect it is doing something from email side, probably checking for spam or virus. So goes back to my question A, how to solve this problem?
Also is it wise to make a dummy account to auto-forward email to different users (eg. firstname.lastname@example.org
will auto forward to email@example.com
)? or is it better to install a mail list software? if so, what is good for ubuntu+ispconfig?
