Sendmail is a complete piece of cake to use and configure, took me about 
2hours to get the hang of it and I never looked back...

There is a very good reason its the number 1 MTA for 25 years...  More 
importantly the amount of plugins, configuration tips and online help is 
massive compared to other mailers.  If someone writes a piece of email 
code, it will nearly always come with instructions for Sendmail.

That said its all down to choice, but to say that Sendmail is 
complicated and difficult to learn doesn't hold water in my book, but 
there again it depends on each individuals circumstances, if I had to 
use a different mailer the only other choice is Exim. 

Sendmail is like masochism you learn to love it the end....and I'm 
really happy :-)
