I am relatively new to sendmail. When I tried to send mail, I got the following in my log:
sendmail: My unqualified host name (DynusT) unknown; sleeping for retry sendmail: unable to qualify my own domain name (DynusT) -- using short name
I did some research on the net and it seems that it has to do with the hostname, so here's my etc/hosts:
127.0.0.1 localhost 127.0.1.1 DynusT.local. DynusT 220.127.116.11 domain1.com 18.104.22.168 domain2.com
How do I fix this issue?
