I believe Francis led you down the right road. In the sendmail.mc file dnl # Uncomment and edit the following line if your outgoing mail needs to dnl # be sent out through an external mail server: dnl # dnl define(`SMART_HOST', `smtp.your.provider') dnl smtp.your.provider is the server that will actually send your mail. This should already be in your sendmail.mc file unless someone removed it. You will have to remove dnl from the beginning and end of the line. and edit smtp.your.provider to your actual server that sends the email In our domain sending email out the normal port is restricted (denied by firewall and vlan settings) on campus except for the campus mail server which I define in my sendmail.mc file as the smart_host. After editing the file you will need to run make -C /etc/mail which updates the sendmail.cf file. Then restart sendmail.
