<p>Other than the Windows networking properties, Is there any way to specify the DNS servers that MercuryS uses, in particular for checking the RBLs listed in the Spam Control?  </p><p>I have three DNS servers listed in the Windows networking properties, and the third one has problems with RBLs, such that MercuryS times out for any good RBL addresses.  I need the 3rd server in the networking setup for other services that run on the Mercury box, so I don't won't to delete it from the networking properties.  I was hoping there was some way to accomplish this within MercuryS itself, like in MercuryE. I haven't looked at 4.71 yet, maybe it has this capability? Thanks,</p><p>Kevin  </p>
