qmail-scanner-pl+EXTmail1.1.0出现问题

yihua2000

环境FC11+qmail1.06+vpopmail5.4.27+extmail1.1.0+qmail-scanner-queue.pl(2.0.6)+clamav0.95.2
原qmail-queue测试没有问题（也就是信体不能显示的问题）
信体不能显示：
compose.pm,我在1037行加了一个\n,
print FD "Content-Transfer-Encoding: base64\n\n";
print FD "\n";
===============但是不知道怎么回事正文就显示了一个换行
Content-Transfer-Encoding: base64

系统加入qmail-scanner+clam
qmail-scanner-queue.pl配置
./configure --spooldir /var/spool/qscan --qmaildir /var/qmail --bindir /var/qmail/bin --qmail-queue-binary /var/qmail/bin/qmail-queue --admin postmaster --domain test.com --admin-description "System Anti-Virus Administrator" --notify admin,nmladm,nmlvadm,psender,recips,precips --local-domains test.com --max-scan-size 100000000 --silent-viruses auto --sa-timeout 30 --sa-faulttolerant 0 --sa-maxsize 256000 --sa-quarantine 0 --quarantine-reject 0 --lang en_GB --debug yes --unzip 1 --max-zip-size 1000000000 --add-dscr-hdrs yes --normalize yes --archive 0 --redundant yes --skip-text-msgs 1 --log-details syslog --log-crypto 0 --fix-mime 2  --ignore-eol-check 1 --scanners "clamscan,verbose_spamassassin" --install 1
===================================================================================================
clam默认。
qmail-scanner2.0.6/contrib/test_installation.sh -doit 成功发送。检测出邮件。
vi tcp.smtp
127.0.0.1:allow,RELAYCLIENT="",QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl"
:allow,QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl"
都通过qmail-scanner-queue.pl扫描。
发送出现问题。系统返回邮件全文如下：

qmail-scanner-queue.pl相关源码如下（line646）：
if (!$quarantine_event && $BAD_MIME_CHECKS && ($headers{'mime-version'} ne "") && !/^([^\s]+).*)$/) {
          #Wow - a header (not header+value) that goes onto another line - not likely!
          $illegal_mime=1;
          $destring='problem';
          $quarantine_description="Disallowed breakage found in header name - not a valid email";
          $quarantine_event="olicy:Bad_MIME_Break";
          $description .= "\n---perlscanner results ---\n$destring '$quarantine_description' found in message";
          &debug("w_c: disallowed breakage found in header name ($_) - not valid email");
          #next;
        } else {
          /^([^\s]+).*)$/;
          $hdr=$1;
          $last_hdr=tolower($hdr);

=================应该是文件头检测出现点问题，大家看看是否还要修改compose.pm,或者本身就是qmail-scanner-queue.pl代码有问题。
另外有谁知道上述代码具体含义的说一下。不甚感谢~~~~~~~~·正想做邮件病毒过滤和反垃圾邮件系统。
注：原cpmpose.pm下不带附件也会出错，加\n后在带附件的情况下出错~
extmail做webmail很不错，特别是现在支持了vpopmail,extman现在看来只能用于postfix了，在qmail下可以用qmailadmin代替，注册程序么可以用vqregister或者自己写一个，可以做成企业级邮件系统。
