当我从 Perl CGI 脚本调用 mutt 时，为什么它会失败？
我使用 Perl CGI 和 C++ 开发了一个数据库。我在将结果发送到邮件时遇到问题。我使用了以下代码：
print LOG "[",`date`,"] Sending mail to $email\n";
system (qq{mutt -s "MMM" -a $zip_file $email < $job_id});
if ( $? == 0) {
print LOG "[",`date`,"] Sending mail to $email :: SUCCESS ::\n";
}else {
print LOG "[",`date`,"] Sending mail to $email :: FAILED ::\n";
}
close LOG;
I have developed a database with the use of Perl CGI with C++. I have problem in sending the results to mail. I used the following code:
print LOG "[",`date`,"] Sending mail to $email\n";
system (qq{mutt -s "MMM" -a $zip_file $email < $job_id});
if ( $? == 0) {

}else {
print LOG "[",`date`,"] Sending mail to $email :: FAILED ::\n";
}
close LOG;

您看到什么错误？
特别是
$!中有什么？可能是 CGI 进程无法执行 Mutt - 如何记录脚本的用户 ID 和当前路径：
Mutt 可执行文件的位置是否在路径中，该用户（可能是“apache”）是否有权执行它？
What error do you see?
In particular, what is in
$!?It could be that the CGI process cannot execute Mutt - how about logging the script's userid and current path:
Is the location of Mutt's executable in the path, and does that user (probably 'apache') have permission to execute it?
您可能还想考虑使用 Net::SMTP 模块，它将直接与邮件服务器通信，而不是依赖系统工具。这是一个更便携的解决方案，并且避免了整个权限问题。
You may also want to look at using the Net::SMTP module, which will communicate directly with the mail server instead of depending on system tools. This is a more portable solution, and avoids the whole permissions issue.
