I have set up a server and need sendmail for my Icinga monitoring. I installed sendmail and played around with it. I am not able to send files to a gmail account.
My mail log is as follows:
Jul 11 16:23:46 li911-131 sendmail[12202]: u6BGNYO4012202: to=sethmschallau@gmail.com, ctladdr=root (0/0), delay=00:00:12, xdelay=00:00:01, mailer=relay, pri=30025, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (u6BGNjJ3012214 Mes$

Jul 11 16:23:46 li911-131 sendmail[12216]: u6BGNjJ3012214: u6BGNkJ3012216: DSN: Service unavailable
Jul 11 16:23:46 li911-131 sendmail[12216]: u6BGNkJ3012216: to=<root@li911-131.members.linode.com>, delay=00:00:00, xdelay=00:00:00, mailer=local, pri=31606, dsn=2.0.0, stat=Sent
I know that the DSN: service unavailable means that Gmail is rejecting me, but why?
I have tried removing a line in the sendmail.mc file:
#DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
:
#127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 li911-131.members.linode.com li911-131
45.53.109.131 li911-131.members.linode.com li911-131
That is my /etc/hosts file, I have the first line commented out in an attempt to not send from 'localhost.localdomain'
I cannot figure out why I am not able to send outbound, any input is appreciated.
