This isn't really related to perl per se but perhaps someone here can offer some enlightenment.

I've a perl mailer script (using Sendmail) to email a notification to a specified email address after a form is filled out.

The sending gets through but the trouble is the email is treated as Bulk Mail by Yahoo as well as Hotmail (don't know about other other mail servers). Hence, the risk that the notification gets ignored because it went into Bulk and not Inbox.

sub notify {  
 my ($recipient, $subject, $message) = @_;
   my $sender = q~"Mailer" <kiat@starhub.com>~;
   use Mail::Sendmail;
   unshift @{$Mail::Sendmail::mailcfg{'smtp'}} ,'smtp.somesite.com';
      my %mail = ( 
     To      => $recipient,
         From    => $sender,
         Subject => $subject,
         Message => $message,
      );
      sendmail(%mail) or die $Mail::Sendmail::error;
}

Thanks for reading :)

Update 1: Looks like it's the smtp server issue. It seems the email is routed through at least two servers being reaching its destination. I read somewhere that the destination email server recognises that sort of email as Bulk or Junk mail. :(

Update 2 (Solution): I found the offending part of the email that's causing Yahoo to treat it as Bulk instead of a normal email. My original message in that email contains a link for the recipient to click on to confirm his account. When I removed that link from the message, the email went to my Yahoo's Inbox, which is the intended effect. I did a confirmation by putting back the link and sure enough, the email went to Bulk. So that was the mystery :)
