Need some suggestions and feedback on my setup(s)..

[Jason Williams]

Hello everyone.

I wanted to post my setup here at my location, what my intentions are and 
the direction I am heading.

Right now, im running FreeBSD 4.9, Cyrus-Imapd-2.2.3 and Cyrus-SASL-2.1.17. 
Everything is working smoothly, including secure authentication as SSL. I 
could not be any happier.

The MTA I am currently testing this with is Postfix, which I have also been 
able to easily integrate with postfix and setup SMTP-AUTH as well.

However the one snag that I have run into is the ability to have the full 
functionality of ACL's on mailboxes. A big part of what our company wants 
to use is shared folders/bulletin boards that will allow users to post 
messages to the mailbox as well as drag and drop emails and attachments 
from within their client. Since the company is growing, there are going to 
be different departments and each mailbox needs to have ACL's to ensure 
only the necessary people can have access to these folders. I must also 
factor in that we are going to be setting up Branch Offices in the future, 
and these locations will need some sort of access to these shared folders 
as well. A murder setup is going to be needed as well.

In a nutshell, ACL usage for me is essential.

However, the problem is that Postfix does not pass the auth credentials off 
to LMTP. (Verified this by asking on the Postfix list..) The only MTA that 
can do this is Sendmail which will work perfectly from what I understand 
with ACL's.

The second option I have is to setup NNTP with the 2.2.3 release. Then 
setup newsgroups for my departments and then setup the ACL's for the people 
as needed.
I have tested this method and it works, but I am not sure if it is the 
method I should implement, especially when I think of the big picture. I 
need something that is going to work all the time and not have to worry about.

So, with that in mind, I wanted to get some opinions from others to see 
what is suggested.

I appreciate it.

Jason
