Hi folks, lately I set up a ubuntu hardy 8.04 server with postfix, clamav, spamassassing with the help of this tutorial (http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04) what I found very useful. As a perfect newbi, i could setup a complete mail server in no time. Thank you Falko. Now it comes my question: on the same server i also configured a PPTP VPN but every time someone connects to that VPN I get this message in the syslog: linux postfix/master[5219]: reload configuration /etc/postfix and on the servers screen I can read: reloading postfix configuration .... done. I think that there is something conflicting between those programs but i cannot find out where i should look. Any help is very welcome Franco
Are there any errors in the mail log? What are the outputs of Code: netstat -tap and Code: ifconfig ?
Hi Falko, I thank you very much for taking your time at my issue As you can see from the messages ouput below, I connected to the server using PPTP VPN from 08.48 to 08.50 At login time the server screen showed these messages: [329654.615881] padlock: VIA PadLock Hash Engine not detected. Reloading postfix configuration ... ...done. and after logout: Reloading postfix configuration ... ...done. The syslog also contains a warning about padlock_sha, what I also cannot understand. Could be that this is the source of the other issue ? Now here are the outputs of the log files messages ouput: Code: Oct 2 08:48:01 linux pppd[17890]: found interface eth0 for proxy arp Oct 2 08:48:01 linux pppd[17890]: local IP address 192.168.0.100 Oct 2 08:48:01 linux pppd[17890]: remote IP address 192.168.0.200 Oct 2 08:50:05 linux pppd[17890]: Modem hangup Oct 2 08:50:05 linux pppd[17890]: Connect time 2.1 minutes.

Hm, good question why Postfix is reloaded, but I see here: http://marc.info/?l=linux-netdev&m=121157849601121&w=2 that this happens here as well, so maybe this is normal. The good thing is that it's just a reload, not a restart, so Postfix is not interrupted.
Oh, I can see. I thank you for taking your time. Next week this server will go live. All the tests went without problems so far, so I hope that there will not be bad surprises.
