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 !!!

unable to bind outgoing SMTP call to 176.31.234.153: Address already in

We're trying to bind the local address, before making the connection.
This is done in order to force use of a specified interface, because
of the transpotr configuration. The bind syscall uses an IP address
and port zero (which should mean "any port", and have the kernel assign
an ephemeral port). There's no good reason for that to fail, that I can
think of, beyond being totally out of ports.
Is the system configured with a very restricted range for ephemeral
ports? Is it very busy, as shown by "netstat -pant"? What OS, distro
and version?
And here is output with strace
[pid 16479] socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 8
[pid 16479] setsockopt(8, SOL_TCP, TCP_NODELAY, [1], 4) = 0
[pid 16479] bind(8, {sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("176.31.234.153")}, 16) = -1 EADDRINUSE (Address
already in use)
Matches the above.
