Exactly, I was about to answer the same.

Postfix has a lot of features build-in Sendmail hasn't. It is feature 
rich and actively developed. Many things you would need a milter or 
complex cf style coding for with Sendmail you can configure in Postfix 
in a simple way.

Please, forget about so call howtos or tutorials on the net. They are 
either dated, giving wrong ideas (no, you don't need a MySQL server to 
run Postfix), failing to explain why the author has done things the way 
he writes them up, or they are simply wrong / violating best practice.

Postfix has a very good documentation (compared to the one shipping with 
Sendmail).

How would you implement the section here titled "Sendmail workaround"
using
Postfix? I use a lot of plussed addresses with the plus replaced with dot 
to deal with broken websites that reject a plus sign in an address. All my 
website logins use plussed addresses with dots. (I also use an email alias 
so my email address isn't my imap login.)

Thanks to both of you: I'll be pursuing those docs.

Here are my so-called tutorials about Postfix with plenty of wrong
information, failing to explain everything:

Enjoy :o)

Thanks Niki! Google even does a pretty good job of translating them for
those of us who are Francophonally challended.

I find it humorous that it talks about "throwing" an application. :)
I guess the original was something like "launching", only in French.
