Sendmail hangs when trying to send mail.

Whenever I try to use sendmail to send email, the server hangs indefinitely and I am forced to restart the ssh session to be able to issue any commands. Even simply typing "sendmail" causes the server to hang.

I have taken the following steps to install send mail:

  1. sudo apt-get install sendmail

  2. I configured the hosts file at "nano /etc/hosts"
    by adding this as suggested by a another user in the help community: " localhost localhost.localdomain pedrogarcez". So my hosts file looks like this:

Your system has configured 'manageetchosts' as True.

As a result, if you wish for changes to this file to persist

then you will need to either

a.) make changes to the master file in /etc/cloud/templates/hosts.tmpl

b.) change or remove the value of 'manageetchosts' in

/etc/cloud/cloud.cfg or cloud-config from user-data pedrogarcez pedrogarcez localhost localhost localhost.localdomain pedrogarcez

The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

  1. I ran the sendmail config using "sudo sendmailconfig" and answered 'Y' to everything.

  • Is anything being recorded in /var/log/mail.log when this occurs? Checking the logs and backtracking from any errors that are recorded is usually the best way to start troubleshooting an issue like this.
