I have a subcontractor who uses web.com as his email provider. Some of their outgoing servers are listed on sorbs.net and postscreen (correctly) rejects this emails but I would like to be able to receive his email.
May 31 15:16:40 mail postfix/postscreen[36888]: NOQUEUE: reject: RCPT from [209.17.115.52]:50612: 550 5.7.1 Service unavailable; client [209.17.115.52] blocked using dnsbl.sorbs.net; from=<contrac...@example.com>, to=<x...@dop.com>, proto=ESMTP, helo=<atl4mhob14.myregisteredsite.com> Since web.com probably has a fleet of mail servers, do I need to find and enter all their IPs into my postscreen_access.cidr? Is there an easier way?
