To allow clients to send mail, you add their address to /etc/mail/relay-domains on tempest, and then editing the /etc/mail/sendmail.cf file on the client from DS to DS tempest.wellesley.edu. This worked on boa, because it already had the sendmail service running on it already. But some of the others, perch, didn’t have sendmail on it. (service sendmail status gave a unrecognized process thing) so I did an ah-broadcast service sendmail status. The ones that didn’t have sendmail processes were shark, minnow, finch (down), orangutan, tamarin (down), cobra, carp, herring, marlin and perch. So if we focus on the other ones and get them sending mail then we can update the other ones to have sendmail process on them.
I updated the /etc/mail/relay-domains file with all of the hosts, first with finch, perch and boa and then with all of them. This way once we get sendmail and the relay from each of the clients to tempest working, the relay-domains will already be ready.
ssh client
add “tempest.wellesley.edu” after DS in the /etc/mail/sendmail.cf
service sendmail restart
confirm that it can send mail
I tried this on thrush, but it didn’t send an email. Then on robin, and it still didn’t send mail. I’m curious if I’m doing something wrong.
