Following this tutorial: http://www.howtoforge.com/perfect_setup_debian_etch_p5 I am installing the software in a OpenVZ VPS. I have installed postfix and saslauth. When I try telnet localhost 25 and I write ehlo localhost nothing happens. So I ctl ]and I exit from the telnet program. Then it is impossible so resolv a name until I restart postfix: ping www.google.com and I receve unknonw host! This is the /var/log/mail.log: Code: Dec 8 14:42:17 vps102 postfix/master[15547]: terminating on signal 15 Dec 8 14:52:14 vps102 postfix/master[16146]: daemon started -- version 2.3.8, configuration /etc/postfix Dec 8 14:54:02 vps102 postfix/master[16146]: terminating on signal 15 Dec 8 14:54:02 vps102 postfix/master[16235]: daemon started -- version 2.3.8, configuration /etc/postfix Dec 8 15:03:55 vps102 postfix/master[16235]: terminating on signal 15 Dec 8 15:03:56 vps102 postfix/master[17459]: daemon started -- version 2.3.8, configuration /etc/postfix Dec 8 15:09:44 vps102 postfix/master[17459]: terminating on signal 15 This is my ehlo localhost: Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

From the mail.log file there is this warning: Code: Dec 8 14:38:51 vps102 postfix/master[15547]: warning: unix_trigger_event: read timeout for service private/tlsmgr May be, I have made a mistake with certificates :-(
in main.cf I have switch off the use of tls, now it is working fine. Code: smtpd_use_tls = no So, there is a problem between saslauthd and postfix, any help? Thanks!
from auth.log I see this: Code: Apr 24 13:47:15 goebbels getty[1992]: /dev/tty1: cannot open as standard input: Permission denied
I have changed the perimission to 755 for /dev/tty* becouse it was only 500. Now postfix/saslauth is working! The problem is that I still get a nasty side effect: when I try telnet localhost 25 everything seems fine, but when I quit and I try to ping www.google.com the name resolution is still not working. I have to restart postfix if I want to have the name resolution working again. I canot see the connection between name resolution and postifix/salslauth.
Name resolution Any help, please? Postfix is working with usetls set to no. But what I don't understand is why when I try to connect to postfix the vps stops doing name resolution
resolv.conf is fine. The name server is the node, which is working fine. The problem occours when I do a telnet on port 25 of the VPS, it I try a ping in the VPS it does not resolve the name. I must restart postix and then everything is fine. Second, if I set smtp_use_tls = yes in the main.cf of the VPS postix hangs without repsonce when I try a telnet on port 25. The main fear is just that there is a bug in OpenVZ. Why, if I connect to postfix, the PVS stops name resolution? What is the connection. Another strange thing is when the name resolution does not work I am still able to telnet to the port 53 of the name server.
