I thought I had replied to this already, but it is not showing in the forum, so here goes again... First off, thanks very much sniper for your response and attention to this. - I checked the accepted domains. My domain is there and listed as authoritative. The weird thing is, I have two other...

Hi all. I have had an Exchange 2003 SP2 box on my network for several years, and recently introduced a 2010 Exchange server. Right now I have them both up and running, and have moved 3 users to the new Exchange server. This worked just fine for a week and a half, but now I have a rather annoying...

Making the 2003 AD controller a GC did fix my problem. Thanks much for your help on this one guys.

Well that makes a ton of sense. I will make the Windows 2003 DC a GC and see if that fixes my issue. Thanks!

Hi all. Here's my situation. I installed Exchange 2007 on a Windows 2008 x64 stand alone server, which is part of a Windows 2008 domain. After the fact, I realized I needed another AD controller and normally I would have went with another Windows 2008 box. In this case, however, I needed to have...

I appreciate the comments guys. I wondered if there was a difference between a server not responding, as opposed to rejecting a message when it comes to MX records. You helped to clear that up for me. As for elgradeperro's comment, I don't know how that would work. What I'm trying to get away...

OK here's my situation. I am supporting a client that currently uses 14 Godaddy POP accounts for email. This client recently purchased an SBS 2003 server, so I planned on having mail directed to their new Exchange server. I set up a new MX record, ptr record for the exchange IP address, etc. All...

Hi all. I am at wits end trying to get WPAD working correctly on my network. I have an ISA 2004 server (SP2) which is acting strictly as a web proxy/cache server. It is a unihomed machine. This machine is also acting as our content filter device. It is running a program called Smart Filter for...

Yep that's the way I do it, and I've never had a problem. Are the accounts you are forwarding to AOL accounts? AOL is notorious for blacklisting various domains. Have you just tried sending test messages to the contacts you set up to see how it works in a non-forward situation?

I agree on dumping the public folder calendars. They are a big pain in the rear. We have them and they have been nothing but a nuisance.

I agree with you completely on separating the two. I inherited this configuration. I'm a big believer in having an exchange server do just that..be an exchange server and nothing else. Honestly though, this config has worked quite well for the most part. I'm baffled by this latest problem, but...

Did you set up the forwarding via a rule, or did you set it up through the "exchange general" tab in ADUC (via Delivery Options)? I have had issues when trying to do forwarding via rules, but I have not had a problem when going through ADUC.

It is running directly on my mail server. With that being the case I don't see how there is any way email can avoid being scanned by Ninja.

We have two MX records. One of them goes through our old firewall (a Sonicwall device), which then forwards via NAT to our exchange server. The other MX record points to our new firewall (checkpoint) and then forwards via NAT to our exchange server. The sonicwall device is disable at the moment...

Here's a copy of a header from a spam message that slipped through. Microsoft Mail Internet Headers Version 2.0 Received: from SEATTLE.mydomain.com ([10.10.1.3]) by Server3.mydomain.com with Microsoft SMTPSVC(6.0.3790.1830); Wed, 23 May 2007 11:38:41 -0700 Return-Path...

Well if you are suggesting that the public folders are excluded from scanning by Ninja, that is not the case. The public folders are indeed scanned by the Ninja product. The only requirement is that they are not hidden from the exchange address book (and in my case they are not hidden). As a...

Excellent thought, but wouldn't the internet header give that away? When I look at the header, the emails are coming from IP addresses outside my organization. Is it possible that an infected machine could fudge the header and make it appear to come from outside? I'm thinking that's not...

I agree that it's extremely odd...nevertheless that's exactly what is happening. For whatever reason these emails apparently avoid any kind of inspection by the Exchange server, or the spam software which is running on the exchange server. It's incredibly frustrating. I've poked around a bit...

Nick your message was apparently cut off. Can you repost when you have a moment? I'm still struggling with this problem and I could use some help. Thanks!

Hi all. OK here's my issue. I am running Exchange 2003 SP2. I use intelligent message filtering, recipient filtering, and I run Sunbelt Messaging Ninja (anti-spam product). Spam which is directed at user accounts is successfully blocked 99 percent of the time. We do have a few mail enabled...
