Hello All, I'm running Cyrus+Postfix+Amavisd-new (Spamassasin+ClamAV).
The problem is that non-encoded 8bit data is not allowed in message headers and Cyrus-IMAPd prevents from any problem by replacing those chars with X. A lot of emails my user get are coming from hotmail host with those XXX in subject header. Hotmail web-interface is not a standards-compliant mail program that does not RFC 2047-encoding on all headers. Unencoded 8-bit characters aren't allowed in headers. That's why Cyrus replaces them with X. I thought I could solve it on the amavis level. As you can see below, amavis warns about "BAD HEADER" > X-Amavis-Alert: BAD HEADER Non-encoded 8-bit data (char F7 hex) in > message header 'Subject' > Subject: \367\345\370\361 \344\351\351\362\345\365\n ^ Is there a way to use function function encode($in_str, $charset) on Subject header when amavis see the "BAD HEADER" in Subject? Where should I enter the encode code? P.S.: Below is function encode($in_str, $charset) code: $charset = "ISO-8859-8"; function encode($in_str, $charset) { $out_str = $in_str; if ($out_str && $charset) { // define start delimimter, end delimiter and spacer $end = "?="; $start = "=?" . $charset . "?B?"; $spacer = $end . "\r\n " . $start; // determine length of encoded text within chunks // and ensure length is even $length = 75 - strlen($start) - strlen($end); $length = floor($length/2) * 2; // encode the string and split it into chunks // with spacers after each chunk $out_str = base64_encode($out_str); $out_str = chunk_split($out_str, $length, $spacer); // remove trailing spacer and // add start and end delimiters $spacer = preg_quote($spacer); $out_str = preg_replace("/" . $spacer . "$/", "", $out_str); $out_str = $start . $out_str . $end; } return $out_str; } $subject = encode(($in_str, $charset); Best Regards, Leon Kolchinsky ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
