I am thinking about switching from Linux on a PC to Macintosh OS X. 
I'd like the change to be maximally continuous, though.  The main
things I do on the Linux system are pretty simple: e-mail, file
editing (with Emacs), website maintenance.  I take it that the file
system on OS X is similar enough to standard Unix that I can transfer
things straightforwardly, and that Emacs is available.  My main
concern is e-mail.  Call me primitive, but I have always used Berkeley
mail (the standard Unix e-mail program), and I like it.  Is Berkeley
mail available for OS X?  If not, is there anything very much like it?
 Are there any other problems I should anticipate in moving from Linux
to OS X?

Hi philosophe,
Yes, Emacs and mail are included with Mac OS X.

As an alternative to using mail, 
you might want to check out Apple Mail(Also included):

To get a feel how mail is used in OS X, 
please read the following article:
[Title: Learning the Mac OS X Terminal]

In case you also like to use pine, you can easily install that along
with other Unix-based apps that are not included with Mac OS X
using fink 
[URL: http://fink.sourceforge.net/]

Possible problems you might run into is if you're 
using Intel-based Processor apps such as Wine

Other than that, I can't think of any other problems you might run into.

"mail cli" "os x"

Please let me know if you anymore questions.
Thanks.

Thanks!

Some nifty things you might also like are the fact that OS X has the
capability to activate its built in mail server very easily.  I'm sure
you will be able to find the correct terminal commands coming over
from linux, but there is a freeware program that will set it up for
you as well.  Search Versiontracker for Postfix enabler.  All the
program does is execute the terminal commands to set things up.  You
don't need to run it but once.

Another option for those who like their mail straightforward is
Eudora.  It is what I've used since 1990 or so in one form or another,
and it is pretty powerful yet simple.
