Sendmail very slow - /etc/hosts configuration












11















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?

  • @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.

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

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

  • 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.
