Emails from Constant Contact being blocked

Emails from Constant Contact being blocked

I have been notified that Comcast has been blocking emails from Constant Contact for the past two weeks.

 

Constant Contact is not an open relay and has strict anti-spam policies in place. Because your filters block emails from Constant Contact I am unable to receive these communications.

I ask that you please help me determine why these emails are being blocked. For further information about Constant Contact or to request more information from them such as log files, the Operations team can be reached at - 781.472.8103 or ops@constantcontact.com.

 

Mail from Constant Contact can be found by the following characteristics for whitelisting:

"Envelope from:" domains:

 

@in.constantcontact.com

@in.confirmedcc.com

 

Sending IPs:

 

All mail from Constant Contact is sent from:

 

IP Range: 208.75.123.0 - 208.75.123.255

CIDR: 208.75.123.0/24

Network/Netmask: 208.75.123.0 255.255.255.0

You need to call Comcast security to try and get this sorted out.  They deal with any blocking issues--------------------
