Hello,

I have a question regards POSTFIX Software.
After installation of postfix on redhat 5.1 we can see on the Firefall side, that the server will create a connection to the ip 131.211.84.186 http;

How can we disable this outgoing connections without to enable iptables?

It should be possible to disable that in the postfix configuration?


Thanks!

The address is from a mirror server on the uu.nl (Utrecht University in Netherlands)
These are a few of the urls going to that address... (it hosts more)
- http://archive.cs.uu.nl/
- http://www.postfix.cs.uu.nl/
To know WHAT it accesses you need the exact URL not just the IP address (especialy for HTTP which support multi website hosting)
(make a packet trace or so and look for the first few outgoing packets after SYN).

It is the main site for postfix, so parts of postfix might check for new versions?

Thank you for explication. I think, that the reason for the outgoing connection was not a postfix, but yum update service.
