[Dspam-user] DSPAM with Exchange Server

2010-07-27 Thread John Holbrook
We're in the process of moving our 500 email users from Groupwise to
Exchange server. I'm rebuilding our dspam box to move from 3.6.8 to
3.9.x and upgrade some other components on the server.

Currently the web interface is the method of retraining emails but
quite a few of our users just never remember to go into it.

What methods are there to easily integrate into Exchange/LookOut? Any
tips/documentation/recommendations would be greatly appreciated.

Thanks in advance.

I use two retraining email address which are not hosted on the exchange 
server.  I then allow dspam to 'deliver' all the mail, but with its 
extra headers.
Then create two rule to sort the mail how users wish.
For some of my users I allow them the outlook 2003/2007 dspam addin (i'm 
working this addin right now) here is a link to how it currently stands.
http://sourceforge.net/apps/mediawiki/dspam/index.php?title=OutlookAddin-Unmodified

The code was donated to the dspam project from wahlfaelschung.de.

retraining for forwarded mail or with watched folder does work, I have 
yet to make retraining with the web-ui work with this addin, but most 
likely something with my installation.

I also have the code for 'dsMON' a service that runs on the exchange 
server, which was donated by Gareth Hastings.  - I have yet to get this 
to compile successfully on visual studio 2008

If you use ClamAV in dspam, then all 'virus' tagged mail will also end 
up on the exchange server.  To stop this going to the the end users, you 
can create a gobal exchange rule to filter the virus mail to an admin 
account then maybe set a purge for mail older than x days.

The plugin works well with 2003 sp0-3, and seems to work with 2007 (also 
it should work with 2000 and 2002)  Outlook 2010 will NOT work and 
requires a full re-write which I'm trying to find someone to help with.

I forgot; you should look at the 'external lookup' feature of Dspam and 
maybe integrate it with your AD.  The Dspam project would welcome any 
setup notes in the wiki for hooking up to Exchange/AD.  ;-)

Don't do live lookups from within DSPAM against your AD if you often have 
directory attacks against your MTA.

If you intend to sandwich DSPAM into a Postfix MTA then I would suggest you to 
have a look at the suggestion from Ralf and Patrick:
http://postfix.state-of-mind.de/patrick.koetter/mailrelay/

If you like to pull from Linux the users from AD then have a look at script 
from Chris Covington:
http://www-personal.umich.edu/~malth/gaptuning/postfix/

If you have often those directory attacks then I would advise to use 
smtpd_delay_reject and set it to no and use something like fail2ban and block a 
bunch of minutes those IPs that do bad things on your MTA. This will not stop 
them but make their life much harder.
