Why Use Berkeley sendmail?
I'm sure many of you are wondering why you should use the free
Berkeley sendmail instead of the implementation shipped by
your vendor with the Operating System. There are a number of reasons.
- Security fixes
- Because of its function and complexity, sendmail has a
large number of security holes. When a new hole is discovered, it's
patched almost immediately in Berkeley sendmail, and a new
version is released. Most vendors (whose sendmails are
usually based on old, buggy, insecure versions of Berkeley
sendmail) will often refuse to release patches, and when
they do it is not usually in a timely fashion.
- Berkeley sendmail is under constant development by Eric
Allman and a team of free software writers throughout the world. New
features, such as spam protection, are integrated into Berkeley
sendmail before any of the vendor sendmails.
- Berkeley sendmail is the de facto standard for the
academic Unix community, and even for some of the forward-thinking
industrial community. There's a wealth of information available for
it all over the Internet.
- Although a vendor may provide support for their
sendmail implementation, it is often costly and they may
not be as responsive to your problems as you'd like. Berkeley
sendmail is used at a tremendous number of sites around the
world, and if you have a little initiative to work on your own
problem, there are almost always other knowledgeable
sendmail administrators willing to help out.
