I have a brand new out of the box Dell PowerEdge T310 running SBS 2011. Our employees at our remote offices can't send emails to recipients outside of our own domain. The workstations at the same location as the server aren't having any problem.

I would at this time like to say "Thanks a lot" to the super-minds at Microsoft for protecting our email server from rogue computers attempting to send fake emails. (Silly me I thought proper login and password conventions would handle that.)

I know this is something dealing with relaying but thus far nothing from any posts I've read have changed anything.

Honestly, if someone is crafty enough to guess one of our login/password combos, let them send emails through our server I don't care!
