Your problem will be that the heredoc closing token 'EOF' need to be on a line by itself with no leading or trailing space. ie

print SENDMAIL <<"EOF";

[blah]

EOF

You can also use the qq operator like this:

print SENDMAIL qq!

[blech]

!;

close(SENDMAIL) or warn "sendmail didn't close nicely";
