I think it's actually 4096 on 2.2 kernels.  However, I don't think this is a
problem with sendmail.  Sendmail essentially only opens one socket at a time
for each entry in the mailq.  Postfix makes simultaneous connections, which
may mean that you'll need to increase the maximum number of files with postfix
even if you don't for sendmail.
