A customer has got his e-mail server on Spamcop blacklist. I tried to fix receiving e-mails from that customer by adding the sending e-mail server to ISPConfig EMail tab Global Filters Postfix Whitelist. But testing shows the emails are still rejected with the same message. Code: Jul 2 11:00:09 myhost postfix/smtpd[27972]: connect from mail.sending.server[11.22.33.44] Jul 2 11:00:09 myhost postfix/smtpd[27972]: NOQUEUE: filter: RCPT from mail.sending.server[11.22.33.44]: <[email protected]>: Sender address triggers FILTER amavis:[127.0.0.1]:1002 6; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.sending.server> Jul 2 11:00:09 myhost postfix/smtpd[27972]: NOQUEUE: filter: RCPT from mail.sending.server[11.22.33.44]: <[email protected]>: Sender address triggers FILTER amavis:[127.0.0.1]:1002 4; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.sending.server> Jul 2 11:00:09 myhost postfix/smtpd[27972]: NOQUEUE: reject: RCPT from mail.sending.server[11.22.33.44]: 554 5.7.1 Service unavailable; Client host [11.22.33.44] blocked using bl.spam cop.net; Blocked - see https://www.spamcop.net/bl.shtml?11.22.33.44; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.sending.server> Jul 2 11:00:09 myhost postfix/smtpd[27972]: disconnect from mail.sending.server[11.22.33.44] ehlo=2 starttls=1 mail=1 rcpt=0/1 quit=1 commands=5/6 The Postfix Whitelist settings are that IP-address, Type Client and Active. I'm not using postscreen or postwhite, saw them discussed now when examining this problem.
The whitelist is the counterpart of the blacklist, it might be that you can not use the whitelist to override RBL's. Switching to a postscreen setup might help here and I considered already to add postscreen support in general to ISPConfig, but did not have the time yet to make myself familiar with that setup.
