Hello all, I am using the sendmail module in a perl script, but having a slight issue.I want to variablise the hostname but when and input that in the FROM section , but I'm getting an error

my $hostname=`hostname`;

sub email {

my %mail = ( To      => 'andr@domain.com',
             From    => "$hostname\@domain.com",
             Subject => " $hash_ref->{three} ",
             Message => "$_[0]"
            );

         sendmail(%mail) or die $Mail::Sendmail::error;

}

Error 
Bad or missing From address: 'DataNode2
@domain.com'

If I try it without escaping the @ sign I get Possible unintended interpolation of @domain in string at aide.pl line 24. Global symbol "@domain" requires explicit package name at aide.pl line 24.

can I get assistance with this please? thank you
