Thanks for the guidance. Now I understand a little bit more how the different modules work. One problem though. I am now using the MIME::Lite module to send my mail with sendmail.

my $msg = MIME::Lite->new(
                 From     =>'johan@domain.com,
                 To       =>'user@hotmail.com',
                 Subject  =>'Registration',
                 Data     =>"Klick on the link.\n\n$link\n\n
                 );
            $msg->send;

However, probably because of all spam being sent nowdays, I can't send the same email twice to a hotmail, gmail address. If I change the from field it's ok but otherwise it won't even hit the spambox. Does anyone now if this is within a timeframe or...just curious
