The following Classic Linux changes are now being done.
Mail arriving for addresses in the domain boxmail.com and all of its subdomains will now be received by the new host aqua-new.rahul.net (which will become our main Classic Linux server soon). Most spam in such mail will be rejected by aqua-new.rahul.net. Mail not rejected as spam will then be forwarded to our old Classic Linux servers aqua.rahul.net and maya.rahul.net.
If you have any valid email addresses within boxmail.com, than your incoming mail should remain unaffected, other than being routed differently.
(If this system works reliably, then the same will be done for all mail in the rahul.net domain. The intent is to have all incoming mail to be eventually accepted by aqua-new.rahul.net. And then, user accounts can be moved to aqua-new.rahul.net without loss of incoming mail.)
