Use `postsuper` to delete from the mail queue.
On recent Postfix versions, you should this in the manual page `postsuper`
mailq | tail -n +2 | grep -v '^ *(' | awk 'BEGIN { RS = "" }
# $7=sender, $8=recipient1, $9=recipient2
{ if ($8 == "u...@example.com" && $9 == "")
print $1 }
' | tr -d '*!' | postsuper -d -
