Hi There have been numerous attempts on one server resulting in entries of the following type in the log:( [xxxx] is a domain for which we receive mail).)
Oct 3 07:05:39 dns1 postfix/smtpd[93611]: connect from mail.dolbeyco.com[70.61.148.178] Oct 3 07:05:40 dns1 postfix/smtpd[93611]: NOQUEUE: reject: RCPT from mail.dolbeyco.com[70.61.148.178]: 450 4.1.1 <[EMAIL PROTECTED]>: Recipient address rejected: User unknown in virtual alias table; from=<> to=<[EMAIL PROTECTED]> proto=ESMTP helo=<FRODO.DOLBEY.priv> Oct 3 07:05:40 dns1 postfix/smtpd[93611]: disconnect from mail.dolbeyco.com[70.61.148.178] Where clearly the remote server is hoping to find we are either open to relaying messages or probing to find email addresses we will accept. users with names that do not exist in the virtual alias table are being rejected. However the same group of servers seem to keep on repeated failed attempts. What I would like to do is after receiving a number of attempts from a such a remote server to automatically refuse connections and reduce the log load. I believe there is a tool for doing that (say after a remote server has a speciofied number of failed attempts). I am sure there is a port that does this but cannot find it!! _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "[EMAIL PROTECTED]"
