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
<AMUVf+m56QtmyuiScINpnzw==_1115946392118_8o8akGcxEeOfSdSuUpLCrA==@in.constantcontact.com>:
Sender address rejected: Access denied;

to=<quinter...@harte-lyne.ca> proto=ESMTP
helo=<ccm168.constantcontact.com>
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?
