Yep, they are spammer scum, one of those companies were (can't say un) subscribing is certain to get you added to many more spam lists and any complaints to them are ignored. I would tell the organization the company they are dealing with is a hive of spammers and they should look for a different provider as many mail servers will reject they mail. But, if you want to receive the mail for a specific user you just need to check for the user earlier in the smtpd_recipient_restrictions, right? check_recipient_access hash:$config_directory/recipient_access check_sender_access pcre:$config_directory/sender_access.pcre, -- Han : This is not going to work.

They aren't always able to weed out customers with dirty contact lists preƫmptively. So some of their traffic is spam, but IIRC they drop and/or reeducate spamming customers. YMMV. I'd remove the rule and watch for unwanted traffic. Report any abuse you find to constantcontact, and see whether their response is adequate. -- Viktor.
SENDEr-ACCESS exceptions
The constantcontact.com domain was added to our sender_access file: constantcontact.com REJECT .constantcontact.com REJECT I must have done this but at some distant time in the past as I have no recollection of doing so. The situation is that now one of the professional organisations our firm belongs to sends its newsletter via constantcontact.com. I can of course simply remove constantcontact.com from the block list. However, given that it is one of only two such entries I must have had considerable provocation to add it to begin with. My researches into the reputation of constantcontact.com does not inspire confidence and tends to support the original decision. However, i may be compelled to allow their servers to connect to deliver this particular organisation's monthly newsletter. At the moment this is what happens: This is what we see in our logs respecting constantcontact.com smtpd[14594]: NOQUEUE: reject: RCPT from ccm168.constantcontact.com[208.75.123.168]: 554 5.7.1: Sender address rejected: Access denied; from= to= proto=ESMTP helo= This indicates that we obtain a recipient address from the connection before it is rejected. Is their a method available to me to permit one recipient address for this sender and block all the rest? Is there a better way to block all traffic from constantcontact.com except for a specific recipent? -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
