I have a Raq 3 that was recently hacked. I did an OS Restore from the CD and then proceeded to apply all the patches in order from here-- http://sunsolve.sun.com/patches/cobalt/raq3.eng.html. After doing this and setting up the main site we use on the box and testing it out I found that any email sent (test sent from a yahoo.com account) to any user was rejected with the following error:

Message from yahoo.com. Unable to deliver message to the following address(es).

: 209.242.xxx.xxx does not like recipient. Remote host said: 553 ... No such user here Giving up on 209.242.xxx.xxx

I needed to get this working ASAP and my Linux isn't great, so I restored from the OS CD again without updating anything and now everything works great. However, I can't install the SSH pkg from pkgmaster.com because it needs the latest OS patch. See below for all that's installed to see why I still feel very vunerable.

Cobalt OS Release 5.0 RaQ3-SecurityRelease 1.1 RaQ3-Update-OS Release 1.0

If anyone has any ideas or any info on what I can do to get things working with all the updates applied?

Please, please let me know.

Thanks
