I am having problems with my mail server guys can someone help? Thanks ever so much to everyone for helping me setup this service though as its working wonderfully only not for one slight problem. After some digging around on the web and sending an email out to an anonymous hotmail address I made say firstname.lastname@example.org (just one I made up to test my smtp server), as I wasnt getting anything in from the same username but googlemail.com. Its coming up with this message back from hotmails servers: This is what I suppose is probably the best thing albeit annoying for me, to protect their servers against spammers. Anyways is there anyway around this problem? I am obviously as it suggests using a dynamic ip address with virgin media at present, but what would you say is the best solution to get around this? Could I use mine as say a relay so I send an instruction out to gmail and then get them to send out an email or, something else? I would appreciate any response. Kind regards and I look forward to a reply, Jeremy.
