Hello,

I need disable the content filtering for some domains on Edge transport server 2013 

For example I want to send encrypted zip files  to contoso.com except any other domains. are there any options to disable filtering lets say for contoso.com only?

Thank you in advance

you can do this at your mailbox server itself using transport rules.

Condition : Any attachment's file extension matches 

Value : zip

Action : Reject the message with the explanation

Value : Attachment type not allowed

Exception : domain is

Value : contoso.com

please let me know for further clarification

Hi,

You can add the IP addresses of email servers to IP allow list, email from mail servers that you specify in the IP Allow list is exempt from processing by other Exchange anti-spam agents.

Add-IPAllowListEntry -IPAddress 192.168.1.10 -ExpirationTime "5/31/2015 15:00"

Or you can configure the content filter so that all senders in the domain contos.com and all subdomains arent checked by content filtering.

Set-ContentFilterConfig -BypassedSenderDomains @{Add=domain1,domain2}
