Post subject:  Sendmail quit working after configuring static IP
My sendmail was working fine until this update:

I just followed directions to enable a static ip configuration on my linode for the purpose of using a NodeBalancer, but sendmail quit sending after I completed the steps here: https://www.linode.com/docs/networking/linux-static-ip-configuration/#centos-7--fedora-20 (from there to the end of the section is all that I needed to change).

I'm on a Centos 7.

I made sure it was running, restarted it, checked the logs, and well, here's the outputs:

Code:
[root@newton ~]# ps -aux | grep sendmail
root 4383 0.0 0.3 90672 3536 ? Ss 22:19 0:00 sendmail: accepting connections
smmsp 4398 0.0 0.3 86116 3188 ? Ss 22:19 0:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
root 4507 0.0 0.2 112640 2320 pts/0 S+ 22:25 0:00 grep --color=auto sendmail


Looks like it's running on all cylinders.

Here's the last 2 attempts to send from the log's perspective (a valid email was used):

Code:
Oct 23 21:07:52 newton sendmail[4332]: s9O27hvv004332: from=root, size=13, class=0, nrcpts=1, msgid=<201410240207.s9O27hvv004332@newton.intelligentdesign.website>, relay=root@localhost
Oct 23 21:07:52 newton sendmail[4332]: s9O27hvv004332: to=me@example.com, delay=00:00:09, mailer=esmtp, pri=30013, dsn=4.4.3, stat=queued
Oct 23 21:08:20 newton sendmail[4345]: s9O28DwB004345: from=root, size=12, class=0, nrcpts=1, msgid=<201410240208.s9O28DwB004345@newton.intelligentdesign.website>, relay=root@localhost
Oct 23 21:08:20 newton sendmail[4345]: s9O28DwB004345: to=me@example.com, delay=00:00:07, mailer=esmtp, pri=30012, dsn=4.4.3, stat=queued




It looks like it's just queued up, but that's where the logs end.

I tried disabling iptables and sending but that didn't make a difference.

Any ideas?
