How to "whitelist" certain addresses in Exchange

hi

i hope someone can help me here. we have a Small business server 2011 with Exchange 2010.
i have a problem that when certain legitimate clients email me i dont get the emails.
all the protection in Exchange is switched on. i have created a Junk Mail mailbox and setup a rule to move any mail that gets clasified as spam to that mail box so that i can see what i have missed.

i have setup a transport rule to try and fix this problem....example, when a certain individual emails me it will change the spam to a number that isnt considered spam, but for some reason its still going into spam.

how can i fix this issue?

thank you

Have you tried this one ?
Set-ContentFilterConfig -BypassedSenderDomains mycustomer.com

You can get the whole existing list typeing get-contentfilterconfig | fl Bypassedsenderdomain

hi Gerald

i will try that thank you.
when i see the first line it makes me think that it will open up a whole domain?
can one do just a bypass sender as in a single sender and not a whole domain?

regards

Hello,

You can use BypassedSenderDomains or BypassedSender as per Microsoft says :

http://technet.microsoft.com/en-us/library/aa996791.aspx

BypassedSenderDomains
 Optional
 Microsoft.Exchange.Data.MultiValuedProperty
 The BypassedSenderDomains parameter specifies domain name values of sending domains. The Content Filter agent doesn't process any content filtering for messages received from the domains listed on this parameter. To enter multiple domains, separate the addresses by using a comma, for example: contoso.com, example.com. A wildcard character (*) can be used to specify all subdomains, for example: *.contoso.com. The maximum number of domains you can input is 100.
 
BypassedSenders
 Optional
 Microsoft.Exchange.Data.MultiValuedProperty
 The BypassedSenders parameter specifies the SMTP address values of senders. The Content Filter agent doesn't process any content filtering for messages received from the addresses listed on this parameter. To enter multiple SMTP addresses, separate the addresses by using a comma, for example: sender1@contoso.com, sender2@example.com. The maximum number of SMTP addresses you can input is 100.

hi Gues

sorry, i have tested this.
not sure if i'm doing something wrong, but i'm still getting the mail in the junk mail box.
this spesific person that sends the mail can send normaal emails to me, but as soon as they attach a pdf or so then it goes into junk mail.

Can you right click the mail in junkbox and copy paste the header there ? Especially the part that gives us the Microsoft SCL score of the mail.

You can also check
Get-OrganizationConfig | fl SCLJunkThreshold

Open in new window


If the number is too low (6 or 7) you can make it 8 or 9 to avoid false positive

Set-OrganizationConfig -SCLJunkThreshold 8

Open in new window
