qmail and another
bbsmail (perl script)
mailgate.pl (perl script)
mail2bbs (exe binary with suid)
-rwsr-x--- 1 bbs bbs 465274 Aug 28 2003 mail2bbs
-rwxr-x--- 1 bbs bbs 2763 Apr 14 18:34 mailgate.pl
-rwxr-x--- 1 bbs bbs 2039 Apr 14 20:17 bbsmail
port 25 by another smtpd
deliver by an exe named by local
what i can do is
write a perl script 'local' replace the orig one
judge the the deliver target to the 'another' email system or bbs?
virus
spam
log
...
if ( $ARGV[0] ne "" ) {
$file_var=$ARGV[0];
} else {
print "usage: local.pl 237453115.32606\n";
exit;
}
...
($file_name,$file_ext) = split(/\./,$file_var);
$dir_name=$file_name%32;
if (length($dir_name) == 1) {
$dir_name="0".$dir_name;
}
-----> but defeated by it
maybe coz of permission
so another script is coming
...
`su - bbs -c "/home/bbs/bin/bbsmail $to_user /$another_mail_dir/$dir_name/$file_var"`;
unlink ...
cat /dev/null > $the_to_do_list_file
