Release notes 'knows all - tells all'.

The most significant change - and it can catch you if you don't
add new users before running it - is that sendmail no longer
runs SUID root by default.  It runs SGID 'smmsp' - and that user
needs to be added along with 'mailnull' user.

It will create a 'clientmqueue' directory in addition to the 
standars 'mqueue'

There are also now two .cf files, the sendmail.cf and the submit.cf
The latter is used for tranmitting and the former is for receiving.

That means you can run sendmail in send only, receive only, both,
or none.  It also does some severechecking on world and group
writeable files/directories and will not run if they are not
correct.  I had to fix an OS/X for friend of mine this way.

There are lots of other changes but those are the only ones you
need to watch out for if you install in the default mode.

Nothing in sendmail is one page :-)  The one site that has the
information is www.sendmail.org.   

The closest you'll come are the release notes and if you stick with
current you'll see starting with the 8.12.0 notes all the changes
that have been made. It is a LOT of information - 99% of which
won't affect most people.  The above are what you really need to
know about.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
