I have FPE 2010 installed on my Exchange Edge 2010 servers.  We tell users if they want to whitelist users and/or domains to update their Safe Senders (or Blocked Senders) list in Outlook.  Then we run a PowerShell commend every night (Get-Mailbox | Update-SafeList).  That updates the Safe Senders list on the Edge servers and those senders bypass the spam filtering.

A customer called in today and said e-mails being sent to a distribution group are being blocked by the spam filter.  You cannot modify a Safe Senders list for a DL.  Furthermore, there is no ByPassAntiSpam attribute for a DL (there is for a user mailbox).  I traced the message down in the logs and verified the e-mail is sent to a DL (there are no email delivery restrictions on the DL) and it was rejected due to content restrictions.

Any suggestions for whitelisting senders for DL or bypassing anti-spam for distribution g

I figured out how to bypass the content filter all together.

$list = (Get-ContentFilterConfig).BypassedSenders

get-distributiongroup | foreach-object -process { $list.add( $_.primarysmtpaddress)}

set-contentfilterconfig -bypassedrecipients $list

 

However, it would be nice to allow the end users to manage their own distribution group safe senders list.  Is there any options to manage the safe senders list for Distribution Groups?  I would rather not disable content filtering for all of the Distribution Groups.

Hi,

Thanks for your share.

If you wanted to modify the Safe Senders List, the link below may be helpful:

Hi Susie,

Thank you for the link; however, I don't see a way to update the safe sender's list of a distribution group.  I see a way to update the mailboxes for members of a distribution group, but not the group itself.  Did I miss something?

Hi,

Thanks for your reply. You are right, that is only useful for a specific user in the distribution group.

Since I am not familiar with Exchange, maybe you can ask in Exchange forum below for professional assistance:

Thanks for your understanding and support.
