Thoughts on Maia Mailguard 1.02a

Thanks for the info.  I'd like to stick with the current option at the moment unless it doesn't work out.  I'm just looking for details on Maia Mailguard.

Cheers

In terms of reducing your own domain to own domain spam - with Exchange 2K3, you can setup sender filtering to filter out mail sent from your own domain (either by the entire domain, or if you have external users using SMTP / POP3, using individual names).

Check out this document for details of how to kill these types of spam messages.

But wouldnt' setting up sender filtering from my own domain.. block ALL messages from my own domain to my own domain?? not just spam?   I see in the headers that the IPs are Russian or Brazilian.  But they're from juser@mywork.com to auser@mywork.com;zuser@mywork.com  and all the recipients are real email addresses this isn't random guessing users.

Now what if the internal domain is domain.local yet the exchange server handles mail for the domain.com .
Plus there's a whack of remote sites connecting back over VPN. Will this affect any of them?  And a number of users on POP3. Why I'm not sure why but I just started here.  

I'm trying to replicate that environment now actually and a little bit stuck at how to get the @mydomain.com address appearing in AD new user creation.  See http://www.experts-exchange.com/Software/Server_Software/File_Servers/Active_Directory/Q_24745811.html?cid=1575#a25375101

If you've got any input on that.  

Not a problem for domain.local / domain.com.

VPN users will send directly to the server and not via SMTP.

POP3 users will have a problem, so you would have to add your users individually except those that use POP3.

The alternative to the VPN / POP3 users is to setup HTTPs over RPC which gives the users Outlook as if they were sitting in the office and sends mail over HTTPS, so again, bypassing the message filtering.

Comment posted in the other question.

Here is a link on how to setup RPC over HTTPS from Mestha - EE's leading Exchange Expert:

Thanks alan will review.  If I follow you. the RPC over HTTPs would be for the pop3 users now and that way i could enable the recipient filtering for the whole domain.

HTTPS over RPC is not essential for the VPN users - it just means they don't have to connect via the VPN to get their mail, only if they need file access.

any issues with users being on poor connections. ie dialup etc?

currently roaming profiles are in play.  So I presume VPN will be required.

Dialup users will be slower than ones using Broadband, but it will work just the same as if they were doing it without HTTP over RPC.

Roaming profles over VPN?

Depends on the speed, but if there is a VPN involved, then no need for HTTPS over RPC.

Excellent. thanks for that. Once I get some input on Maia itself and close this thread I'll be sure to award you full points for your input also.

Not sure if you will get other Experts popping up now without requesting attention at the top as there are lots of posts in this question already and most Experts may ignore it because of the many posts.

Yea mods closed my request for attention since they felt the thread was active and you were helping me lol.  I have to wait until tuesday to request attention.  I'll award you the points when I close. Thank you much!

No problems - hope your next call for experts is successful.  Appreciate the offer of the points.  If someone else helps you with the Maia Mailguard - be sure to share the points accordingly - especially as you have said that you will award me the points - another Expert may read that and say "There is nothing in it for me - so I won't bother answering".

Gotcha. No I think I can award 500x4 so I can definitely award everyone. And will. Cheers.

You can split the 500 points up between Experts and if you award an A grade - whatever you split, gets multiplied by 4.
