Recently I have had problems with openldap running out of file descriptors, but what is more troubleing is that Sendmail hard bounces when the map is not available.

I will almost never reply to top-postings which include a full copy of the previous article(s) at the end because it's annoying, shows that the poster is too lazy to trim his article, and it's wasting the time of all readers.
