Are you sure? I've just done a test on this machine, to which I've
opened 2 SSH connections. With one of them, I've sent a mail. With
the other one:

ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:21:27
2757
ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:21:30
3067
ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:21:56
3462
ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:22:11
4
ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:22:15
29
ay:~> cat /proc/sys/kernel/random/entropy_avail                        <0:22:24

The entropy dropped from 3462 to 4 just after I've sent the mail!

Concerning the mail, it is still in the queue, but the exim4 log file
doesn't show any error! And "exim -qff" doesn't solve the problem.
Here are the contents of /var/log/exim4/mainlog:
