RE: best-practice document explaining how to prevent spam msgs?
Jesse, one thing you can do is enable reverse-lookups for any mail host that is delivering mail to you. This will slow down your server a bit and cause a bit more traffic, but it should block some of that spam. Not the best solution by a long shot, but it's at least something. tx, Sasha -Original Message- From: Jesse Rink [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 10, 2002 7:59 AM To: MS-Exchange Admin Issues Subject: best-practice document explaining how to prevent spam msgs? Alright. We do not have any content filtering software on our Exchange server at this time. As most Exchange admins are aware, content filtering software can cause just as many headaches after it's been installed prior to it being installed at all. The best way to prevent unwanted spam seems to be for users NOT to give out their email address over the web (surveys, etc.), not to sign up for newsletters, not to do online ordering, and other obvious things. I'm wondering if there's a document out there that someone has used that explains these things in detail? Basically a "How to prevent unwanted email - faq" or something like that that I can send out to our users... Any idea?

RE: More NAS Information
We have used Netapps NAS product for about 1.5 years now with very few problems. We have a Netapp F740 with a 45 gig datastore in San Mateo that takes only 1.5 hours to backup and about 2 to restore. Try that with a tape solution. We can also add disks on the fly and dynamically expand the volume that Exchange sits on. Performance is robust. Our two other filers (another 740 and a 720) also host exchange databases that are smaller (20 gig and 13 gig) without any difficulties. I have read many articles and posts over the last year on the topic of Exchange and NAS. Most seem to come from a position of "I heard that..." and "MS says...". Don't believe the hype. Do your own testing, do your own evaluations. NAS is used so infrequently (relatively speaking) with Exchange that there are scant articles available that honestly evaluate the solution. Now that I've told you about the good, here comes the bad. The software and license fees (yearly) for Netapp's solution for Exchange are extraordinary. It sucks to pay $5,000 a year per filer for their software. The price-per-meg is also ridiculous for netapp drives compared to market. You need some fairly high level people (both Exchange and Windows) to understand and implement the NAS solution from Netapp. Once you are on the platform, it's difficult to move off of it (many good things about it that I would not want to lose). Many HA solutions will not work with the Netapp since it uses it's own "special sauce" OS. Also, Netapp's Exchange solution is not always well supported; their support is flaky depending on who you get on the phone (some techs are excellent, some can't speak English). my two cents. -Original Message- From: Milton R Dogg [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 11:09 AM To: MS-Exchange Admin Issues Subject: RE: More NAS Information The fact that this is now supported does not mean that it should be looked at in any other light now.

SnapManager for Microsoft Exchange 2000 and filers meet these requirements. Q317173 puts NetApp on par with vendors providing direct attached storage solutions for Exchange 2000.

Anyone replicating Exchange across a WAN link?
Hello, Has anyone successfully "clustered" an Exchange database across a WAN link? Anotherwords, all the benefits of clustering Exchange, but a situation where the other Exchange server is sitting at a datacenter, ready to take over it's partner (across a WAN link) role. I have read about NSI's GeoCluster and that sounds like it would work, but hoped someone had practical experience with the package (or others if they exist). tia, Sasha List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
RE: IMC in 900-1200 msgs and outlook wont open attachments
If you are using something like trend-micro in mapi virus mode, any attachments received by the exchange server need to scanned in sequence by the virus software. If you are getting tons of mail and the server is not powerful enough to quickly scan the attachments, you end up with a backlog of attachments that have not been scanned. Hence the weird message. -Original Message- From: Craig Ramsey [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 21, 2002 1:13 PM To: MS-Exchange Admin Issues Subject: IMC in 900-1200 msgs and outlook wont open attachments Maybe someone can give me an idea of what to do for this problem. When our Exchange 5.5 server's IMC inbound queue hits about 900-1200 messages, our users who use Outlook 97-2000 cannot open any attachments. The message arrives, but when you try to open the message or attachment, it prompts with "Could not open one or more attachments" box. All we can do is wait for the number in inbound queue to drop to about 200 and then we can start to open attachments again. The CPU, mem, and disks show everything is fine. Has anyone had a problem like this before? Is the server just finally overloaded? Specs: Netfinity 5500 2x450 CPU 2 GB RAM Raid 5 (10 rpm drives) for store Any help is appreciated.

According to the documentation, I should be able to put in /exchange/ and put the administrators username and password in the log on screen. It just repeats the log on screen 3 times and then gives a 401 error. Implicit log on works correctly.

RE: Recovering lost space
If the sending ISP has a policy of resending mail, yes, you would eventually receive the email, but if an ISP does not retransmit email that has already bounced once, it disappears into the ether. -Original Message- From: Ray Zorz [mailto:[EMAIL PROTECTED]] Sent: Friday, March 29, 2002 2:42 PM To: MS-Exchange Admin Issues Subject: RE: Recovering lost space ??? If your ISP doesn't hold them, they'll bounce around the internet and eventually show up.

I don't know how the backup handles the whitespace. If it compresses the heck out of it, great. But in my last environment, 70 gigs is a lot of tape and time.
