It takes ~15 seconds to send single e-mail using sendmail.

/var/log/mail.log:

Jul 31 09:52:42 piotr-probook sendmail[2912]: My unqualified host name (piotr-probook) unknown; sleeping for retry

/etc/hostname:

piotr-probook

/etc/hosts:

127.0.0.1   piotr-probook localdev localhost
192.168.1.1 router

/etc/mail/sendmail.cf:

# hosts file (normally /etc/hosts)
O HostsFile=/etc/hosts

Obviously I can ping piotr-probook host and HTTP server popups in browser when i type url http://piotr-probook

What am I doing wrong? How to fix the problem?

  • Your question and Problem is unclear. Please add more information about what you're trying to archive and what your Problems are (e.g. How do you use sendmail? In a PHP script? Python? Java? Is Apache involved?). Basically: What are you doing? – mondjunge Jul 31 '13 at 09:20
  • @mondjunge My problem is quite clear. It takes ~15 seconds to send single e-mail using sendmail. I even posted the cause of the issue (see log), and I am just asking how to fix it. I just want to execute `sendmail -t mail.txt`. No PHP, Java, etc. plain sendmail. – Piotr Jul 31 '13 at 09:55

The above answer didn't work for me. So I am posting here what I have done to make it work.

Installed send mail through terminal

apt-get install sendmail

then opened the hosts file

# edited from: sudo gedit etc/hosts
sudo gedit /etc/hosts

replaced the the line

127.0.0.1 localhost

with

127.0.0.1 localhost localhost.localdomain mydomainname

To get the domain name please type

hostname

in terminal and run.

restart apache

sudo service apache2 restart

    sendmail should not be related to apache – Zitrax Jan 30 '15 at 14:54
  • @Zitrax i didn't get you. Can you please explain what do you mean? – Mad Angle Apr 02 '15 at 06:16

    Your last step restarts apache, I just meant that shouldn't be needed for fixing the sendmail issue. – Zitrax Apr 02 '15 at 07:38
  • The apache restart ins't necessary I'm guessing, since you changed the hosts file and it is independent form apache. Anyway, I might be wrong and restarting apache also does something weird to sendmail, maybe it touches some files used by both Apache and Senmail but I doubt it. – loco.loop Sep 01 '16 at 19:13

Got the answer at superuser.com https://superuser.com/a/626219/242163:

Sendmail requires that the result of "hostname" be a fully qualified domain name to start cleanly.

Set the hostname to something like piotr-probook.localdomain and update /etc/hosts.

/etc/hosts

127.0.0.1   piotr-probook.localdomain piotr-probook localdev localhost
