Hi,
What is the best way of checking the ulimits being applied to a daemon
user such as postfix, since it's not a good idea to give this user a
shell?
Thanks,

In RHEL 5 the ability to check what your current limits are was added in
/proc/$pid/limits:
# uname -a
Linux foo 2.6.18-92.el5xen #1 SMP Tue Apr 29 13:31:30 EDT 2008 x86_64
x86_64 x86_64 GNU/Linux
# cat /proc/self/limits
