yeah, the columbia user and i decided to run some other tests with the e-mail problem from dreamhost server to the columbia.edu server.
i tried sending a mail to his alias at vanderbilt which forwards to his columbia e-mail, phone, and a couple others. well, we got a bounce back from the columbia address still. so that didn’t work either
yeah, it certainly seems that columbia has decided to block anything that may contain an origin from dreamhost even within a forward.
thanks for the help and tests.
