Pagi Pak,
Kebetulan tadi ada yg membahas soal backscatter spam, solusinya adalah dengan SPF dan DKIM. setelah sy mencoba mengaktifkan kedua fungsi ini dan saya sudah coba test jalan. tetap saja backscatter spam tembus. terbukti dengan email ini dari salah satu domain yg maybe mengaktifkan "when virus found,send notification to sender" ini artinya bahwa SPF dan DKIM nya gagal? Berikut feedback dari antivirus : -----Original Message----- From: "MailScanner" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Date: Wed, 5 Sep 2007 12:12:10 +0700 Subject: Warning: E-mail viruses detected Our virus detector has just been triggered by a message you sent:- To: [EMAIL PROTECTED] Subject: Good day Date: Wed Sep 5 12:12:10 2007 One or more of the attachments (document.zip, document.htm .exe) are on the list of unacceptable attachments for this site and will not have been delivered.
