But I have ssh access to another computer, where it does give a response. So, I have forwarded mail.isp.com:25 using ssh to localhost:10025. > "smarthost" being something like "mail.isp.com" or (better) their IP > address. Will they give you an MX address?

I have got mail.isp.com:25 to localhost:10025. So, *my* machine has their mail server on port 10025. Now, all I want exim4 to do is use localhost:10025 as the smart host, but it frowns at the word *localhost*! Thanks for patiently anwering my query, hope it's clear now. Now, can you think of a solution? Thanks again. Kumar -- Kumar Appaiah, 462, Jamuna Hostel, Indian Institute of Technology Madras, Chennai - 600 036
