Can I delay a message send in Exchange 2007?
Does anyone know if there is a way to delay a message send? I am running Exchange 2007 and am having an issue where email is getting sent to phones via Activesync 'before' it gets scanned as SPAM.
What occurs is an email is received, then immediately sent to the Activesync device, then scanned for SPAM. Accordingly all emails are getting forwarded to the Activesync devices prior to the scan. Then the scan occurs (usually taking about 2 seconds) and the email gets sent into a predefined spam folder. My problem is the Activesync devices are getting killed by too much spam.
Is there a way to delay the Push for like 2 or 3 seconds? This would allow my spam filter enough time to scan and move before the push to the Activesync device.

HI,
This should not be the case at all....how have you designed your setup? Can you elaborate, there is something fundamentally wrong here !
Thanks

I would agree that there is something fundamentally wrong. It's a simple setup in that I'm using primary defaults on Exchange 2007. Nothing (to my knowledge) that's out of the ordinary.
Email gets sent to both workstations and Activesync devices immediately upon receipt at the exchange server. Even Previews on the workstations popup at an alarming rate only to go away into the Spam folder after about 2 seconds.
If you can be more specific I'll gladly provide you with as much info as you need.
Thanks!

what is your scanning process ? what antispam are u using
From your description, it sounds like you are using a client side spam filter. If that's the case then Exchange is working as intended. If you need filter at the server then you will need a product that uses a sink to catch the messages prior to delivery or a front end appliance that catches them before delivery to the exchange server.

Using Cloudmark Server Edition.
where is it installed ? on its own server or what ?
ASKER
Yes, Cloudmark Server Edition. Installed on my Exchange Server.
I just read the description of how Cloudmark Server Edition works and what you are facing looks to be a flow in the software design!
i would invest in a SMTP filter or, easier, just enable the builtin anti-spam features of exchange

The built in Spam feature is configured. However Cloudmark offers a feature that Exchange does not (at least to my knowledge) in that it allows you to setup individual SPAM folders within Outlook to periodically check for false positives.
My customers like this feature.

I didnt mean to be rude, sorry if you felt so, all I wanted to say was that there seems to be sth wrong and well you did clarify it.
Now I have not used Cloudmark , can you please explain how do external mails hit ur environment, first they hit Exchange Server or Cloudmark ?

No no no. Not upset at all. I appreciate the help!!!!!
Although I'm not an expert in Exchange, I'd have to believe that email hits Cloudmark first, as most of them are still not getting rejected by the Anti-Spam filter in Exchange. But not sure how I check this.

Cloudmark uses MAPI to communicate with exchange and retrieve emails from the mailbox, so the email has to reach the mailbox first which explains what you are experiencing !
The issue is with the anti-spam You can't fix it with exchange unfortunatly

It seems that Cloudmark handles the emails first, then based on a response from their server determines what to do with the email (either forward to the end user or hold in the predefined SPAM folder).
Is there a way to have Exchange's built in Anti-spam feature monitor the email first before passing it on to Cloudmark? It would seem to me that Exchange would kickback likely 100's of these if not more thereby reducing the number that get through to the clients desktop and/or phone.
I'm trying to find a way that I can have Exchange kick back SPAM email with NDR's and allow the ones that do get through to be managed by Cloudmark and saved in the SPAM folder.
Am I just dreaming outloud? lol.

it is clearly stated that cloudmark uses MAPI then it retrieves the email AFTER it is delivered to the mailbox and not first.
What you want is an anti-spam that does SMTP inspection so spam is detected BEFORE it reaches the mailbox

Would delaying the delivery of the email to the users inbox, even if only for 2 seconds resolve this issue and give Cloudmark enough time to move the invalid emails?
I don't think it would, i have never worked with Cloudmark but the word connects to MAPI means that it is retreiving the email FROM the mailbox
ASKER
And wouldn't Exchange's built in Anti Spam features automatically kick back the emails? I am using Spamhaus, Spam Cannibal and Sorbs as my IP block list providers
ASKER
So the email goes to the users inbox first, then gets managed by Cloudmark?
ASKER
To be honest, it really doesn't make a lot of sense to me in that it's kind of defeating the purpose of a spam filter, if, for each and every email, it still gets sent to the inbox, the preview windows pops up and THEN the email gets moved?
If that's the case, the only benefit is that the end result is the spam is getting moved. The annoying popups are still occurring and the traffic hasn't been reduced, right?
