I was notified that Mail::Sender (sending emails through SMTP via socket()s) doesn't work with Perl 5.8 with some SMTP servers if the script runs under Windows.

I tried to compile 5.8 myself (Win2k, perlio enabled) and used a TCP/IP sniffer to see what do I send to the server, and sure enough ... even though I do binmode($socket); the \x0D\x0A I send into the socket gets changed into 0D0D0A.

I tried to use binmode( $socket, ':raw:perlio') as well as binmode( $socket, ':raw'), but it did not change the results at all.

Adding 

use open OUT => ':raw';

or 
use open OUT => ':raw:perlio';

into the module did help though. Since I would like to be able to support 5.005, I cannot just add the use statement into the module, but 
BEGIN {
    if ($] >= 5.008) {
        require 'open.pm';
        'open'->import(OUT=>":raw:perlio");
    }
}

seems to work fine.

I'm also using

binmode($s)
    unless ($] >= 5.008);

later though that's probably not necessary.

I don't like this solution though. Is there any other (better) way? What should I do?

Thanks, Jenda
