RE: POP/SMTP Proxy

["Mike" <mike () coenholdings ie>]

I have been using a combination of Mail Marshal and Sophos AV for the
past couple of years and have found it to be extremely reliable and
versatile, not to mention that on the few occasions when we have had
problems/queries the support people have been very helpful.
As a one man band one of the major attractions for me is the lack of
maintenance required (I do have real work to do) the system can be
programmed to send you an email whenever anything happens which means
that long before your users suspect you have a problem you can have it
fixed. Sophos is integrated with Mail Marshal via a .dll interface and
downloads the AV updates to my mail server on an hourly basis (as new
IDE's become available) these are also pushed out to our desktops using
the same method. Marshal also allows you to filter email by content,
spam filters, remove or quarantine mail with unwanted attachment types
(very useful for those humorous video files my users friends seem so
intent on sending in and a feature that has on more than one occasion
saved us when we have received a new virus in the hours before an IDE is
available).
An added advantage of this system is the reporting which reports on
everything (useful for pointing out why users x,y and z should possibly
spend more time working and less time sending each other joke emails and
for justifying the small amount of time you will spend administering the
system to management). If you have any queries I will be happy to answer
them, or refer you to someone who can.
Our remote users can either dial up our network via a modem, or some
have their own email addresses remoteuser () someisp com and a simple
Marshal rule forwards the mail on to their external account after
scanning for viruses and content whichever is more convenient for them.

P.S. I don't work for Marshal it just sounds like it

Subject: POP/SMTP Proxy


I am looking for anyones experiences and recomendations using a POP/SMTP
proxy configuration for email and using it to filter/virus check
incoming
and outgoing
email.

Currently we are an MS shop and trying to address a couple of issues.
Firstly we
have outsourced our email services through our Internet provider however
they
block SMTP access if you do not connect through the company Internet
connection
(ie remote dialups). Secondly we would like to try and stop email
viruses
etc
before reaching the workstation.

Thank you,
-Jimmy
