用sendmail发送HTML格式的邮件

先将来自HTML页面的数据解码，再调用unix系统sendmail命令即可。 

例如下：

#!/usr/local/bin/perl 
# 
&readparse; 
print "Content-type: text/htmlnn"; 
# 
#********* BEGIN BODY******************** 

#******** END BODY************************ 
# 
# EACH VALUE IN THE HTML FORM WILL BE CONTAINED IN 
# THE THE @VALUE ARRAY. 
sub readparse { 
read(STDIN,$user_string,$ENV{'CONTENT_LENGTH'}); 
if (length($ENV{'QUERY_STRING'})>0) {$user_string=$ENV{'QUERY_STRING'} 
}; 
$user_string =~ s/+/ /g; 
@name_value_pairs = split(/&/,$user_string); 
foreach $name_value_pair (@name_value_pairs) { 
($keyword,$value) = split(/=/,$name_value_pair); 
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C",hex($1))/ge; 
push(@value, "$value"); 
$user_data{$keyword} = $value; 
if ($value=~/print "Content-type: text/htmlnnNo SSI permitted"; 
exit; 
}; 
}; 
}; 

#E-MAIL SUBROUTINE 
#ADD "&email(to,from,subject,text)" TO YOUR SCRIPT 
#REMEMBER TO BACKSLASH THE @ WHEN YOU ARE NOT USING IT IN AN ARRAY 
#FOR EXAMPLE: 
# $to='robyoung@mediaone.net'; 
# $from='foo@company.com'; 
# $subject='Thank you for your inquiry'; 
# $text='Dear readernnThank you for your recent inquiry.'; 
# &email($to,$from,$subject,$text); 

sub email { 
local($to,$from,$sub,$letter) = @_; 
$to=~s/@/@/; 
$from=~s/@/@/; 
open(MAIL, "|/usr/lib/sendmail -t") || die 
"Content-type: text/textnnCan't open /usr/lib/sendmail!"; 
print MAIL "To: $ton"; 
print MAIL "From: $fromn"; 
print MAIL "Subject: $subn"; 
print MAIL "$lettern"; 
return close(MAIL);
