mail server

Hello PLUG,

    My company is currently using an NT based mail server called Post.Office
from software.com.  To be truthful, it stinks and is a resource hog.  They
have agreed to let me install a Linux based mail server.  I do, however,
have a bit of newbieitis when it comes to mail servers on linux.  Will
sendmail be able to replace our server?  Can it to POP and SMTP?  We have
about 200 accounts to move over, will sendmail be able to handle them all??
If not, are there any other mail servers for Linux that can do all of the
above?  Thanks a thousand times in advance.
