<p>Assuming you can obtain the IP addresses of locations you want to communicate with, it is quite straight forward.</p><p>Firstly locate a file called HOSTS on your PC, on my machine it is C:\WINDOWS\SYSTEM32\DRIVERS\ETC\HOSTS</p><p>Then for each location make an entry in the HOSTS file.  This becomes your local DNS server which will perform the translation from Internet service name to its IP address.</p><p>One caveat to be aware of, some sites rotate through sets of IP addresses through what is called DNS switching, for performance/bottleneck</p><p>resolutions.  So it would be best to treat this solution as only temporary.  </p><p>There is a site used actually to solve spam and other unwanted sites, which points bad server names to 127.0.0.1 which is a dummy location and will then <span style="font-size: 10pt;">route messages to these unwanted locations to garbage and not transmit them. Using this file you can set up a local DNS service.

Recently could not access mail and HTTP normally on several sites I help maintain.  After running IPCONFIG /FLUSHDNS, no change. Using the host IP address I was able to access the Control Panel (cPanel), run my FTP client (Filezilla), and do Webmail (roundcube). While things are now back to normal, is there a way to configure Pegasus Mail such to upload/download mail using the host IP address rather than the site mail server names? KSQR
