We have used MailMarshall for over 5 years and have been very happy with
it.

I am wondering what everyone is using on your Exchange server to filter
spam and virus emails.
I am currently using Antigen, but am thinking of switching to a Trend or
Gfi Mail suite.
Any recommendations or experiances??
Thanks so much.

We're using Message Labs (www.messagelabs.com) for our Exchange Servers
in both North America and Asia. It's working great for us!

We use Postini, which is an outsourced spam filter. We just pay them a
monthly cost. It does make it nice because it's less hardware to worry
about but may be more $$$ in the long run. I'm looking at GFi or even
Barracudea after our contract is up. Our current solution does work pretty
nicely but I haven't found a reason to leave before the contract is up for
another two years.

For Spam I really like ORF (Open Relay Filter) from VamSoft. For $99 (may have gone up since we bought it) it is a very reasonable product with excellent filtering capabilities. It does a whole slew of tests in addition to the namesake open relay test. You can maintain your own blacklists and subject/content filtering and best of all a year or so ago they added automatic whitelisting if outgoing email addresses. So users can whitelist a sender simply by sending them a message. We still use SpamBeyes at the desktop level s a backup filter.

For antivirus I am getting really dissatisfied with Symantec...not just for email but all infection methods.

we used GFI and were not very happy with its spam filtering, recently changed to mail foundry (hosted service), it is working much much better for spam and antivirus. cost is very reasonable. $1/mailbox/month. with the first 10 mailboxes for free(for now at least)

I have GFI and it catches a lot. We have it setup to delete any obvious
junk mail (directory harvest, DNS black List, etc.) and send all others
to the user's junk mail folder in Outlook 2003. The user then can delete
all the junk or look through it for false positives. You do have to
train the Bayesian filter and let it learn from your outbound messages.
It also will scan your address books and ass those to the white list. It
also adds all outbound mail recipients to your white list. The only
thing I do not like about it: all settings are global. I tried Mail
Frontier and it did not catch nearly as much as GFI.

Nancy,

Exchange 2003 SP2 comes with Microsoft's intelligent messaging filter
(IMF). It is not as robust as the third party app's but the price is
right. I too am running E-trust with an Exchange agent, has it been a
problem for you?

I use AppRiver to filter spam and viruses. All my mail is sent to them
first where it is sent thru 3 filters then forwarded to my server. Yes
there is a delay on delivery, but I can wait another 5 seconds to get
rid of over 210,000 per week of junk. Keep in mind that all of that
does not come down my internet pipe, so it is not slowing down anyone
trying to get out.

Nancy,

We use Postini as well and have many of our customers using it too.
Everyone I've talked to seems to love it and it definitely takes the
pain away from companies having to manage a solution on their server. If
you are a big enough client then you can get a better price, otherwise,
it would be beneficial to go with a third party reseller to keep your
cost/mailbox under $5.00/box. Here's a just a couple of benefits:

Virus Scanning

Automatic Spooling

Individual user interface

Unlimited amount of aliases per user

Unlimited amount of sub-domains per account

Postini keeps their end up-to-date

The way we typically configure it is to direct the MX records of each
domain to one of the four Postini servers and from there, Postini will
forward to our Exchange server. On the server side, we create a filter
to only allow incoming mail connections from Postini's IP addresses -
they give you the ranges. This will ensure the only thing trying to hit
your mail server is Postini and not some hacker trying to brute force
their way in.

Let me know if you need any additional information. You can contact me
directly using the information below.

Thanks,

We use Postini also, and love it. There are a ton of advantages.
Ironically today, I found out our mail server was blacklisted. I did
all the normal checks with my exchange server, and found no problems. I
called Postini. He reassured me this happens randomly, and took care of
the headaches involved with getting us removed from those lists.

One of the other great selling features is all the spam mail network
traffic never hits your site, therefore, doesn't consume precious
internal bandwidth. As mentioned below, the offsite spooling capability
can be a godsend.

I have been running Antigen on my Exchange server and E-trust on my

have much faith in the CA software and I was having problems configuring
it.
Antigen/sybari (now Microsoft) has always been good at catching so much
and is configurable,, but I'm not sure I want to continue with it. But
it catches to much virus and spam I don't want to do with out something
better.

We also run Trendmicro for virus / spam scanning at the server level,
and at the client level. So far, after running Symantec for the
enterprise, this has proven to be the most non-invasive, and
administrator friendly package I have used. The scheduled reports are
awesome. Realtime notifications are awesome. Price is reasonable.

I am wondering what everyone is using on your Exchange server to filter
spam and virus emails.
I am currently using Antigen, but am thinking of switching to a Trend or
Gfi Mail suite.
Any recommendations or experiances??
Thanks so much.
Nancy

There's a good reference here:
http://www.msexchange.org/software/Anti-Spam/

We use Surfcontrol Email gateway and it really works well for us,
although I'd recommend staying away from their version 5.5 until they
get the bugs sorted out.

Really important is to look for something that can reject mail at the
receive service before it accepts the whole message. It takes a lot of
load off your server. Surfcontrol can do this for RBLs, and also any
blacklist you create. It also can protect against directory harvest
attacks (trying random address until it gets one that works), which cuts
out about 20-30% of our spam. That's a must have feature.

That's the cool part about a service like MessageLabs, etc. You're mail server
doesn't spend any time at all sorting out spam and you're bandwidth is lower
as well.

I am just having the worst (worster?) grammar day...

Thank you this sounds very interesting.

We use Postini also, and love it. There are a ton of advantages.
Ironically today, I found out our mail server was blacklisted. I did all
the normal checks with my exchange server, and found no problems. I
called Postini. He reassured me this happens randomly, and took care of
the headaches involved with getting us removed from those lists.

One of the other great selling features is all the spam mail network
traffic never hits your site, therefore, doesn't consume precious
internal bandwidth. As mentioned below, the offsite spooling capability
can be a godsend.

Nancy,

We use Postini as well and have many of our customers using it too.
Everyone I've talked to seems to love it and it definitely takes the
pain away from companies having to manage a solution on their server. If
you are a big enough client then you can get a better price, otherwise,
it would be beneficial to go with a third party reseller to keep your
cost/mailbox under $5.00/box. Here's a just a couple of benefits:

Virus Scanning

Automatic Spooling

Individual user interface

Unlimited amount of aliases per user

Unlimited amount of sub-domains per account

Postini keeps their end up-to-date

The way we typically configure it is to direct the MX records of each
domain to one of the four Postini servers and from there, Postini will
forward to our Exchange server. On the server side, we create a filter
to only allow incoming mail connections from Postini's IP addresses -
they give you the ranges. This will ensure the only thing trying to hit
your mail server is Postini and not some hacker trying to brute force
their way in.

Let me know if you need any additional information. You can contact me
directly using the information below.

Thanks,
