Sujet: Re: [exim] Need more informations about remote_smtp defer exim4 log
What do you mean by very restricted range for ephemeral port? How can I
know that, because it's not me who done the server/configuration
installation.

Here is output for uname -a

Linux 3.10.23-xxxx-std-ipv6-64 #1 SMP Tue Mar 18 14:48:24 CET 2014
x86_64 GNU/Linux

And here is netstat -pant, output is amazing !!!
