[TriLUG] Network file system.

[Jon Carnes]

Postfix is as close to a drop in replacement for sendmail as you get.  
Under normal circumstances it does everything that Sendmail does.  The 
exception is that the Postfix does a superior job of handling virtual 
domains.  In fact, Tanner moved TriLUG over to Postfix to solve a problem 
we had with virtual hosting.  
Sendmail could have handled the problem with a recompile and the addition 
of another configuration file to handle reverse mapping of email addresses, 
but Postfix was a simple drop in replacement that handled the problem.

Other pluses are that Postfix doesn't run as a monolithic deamon, it 
actually runs as a modularized application where each module only has the 
rights necessary to handle its specific job.  The net effect is that 
Postfix is much more secure than Sendmail.  

Another plus for Postfix is that it can handle much more mail using much 
less processor and memory than Sendmail. 

Finally, Postfix also integrates with LDAP.  The install comes with an LDAP 
integrations example.
