Dear Maintainer,

The current queue unit file (/usr/lib/systemd/system/dma.service) command goes into the background and is killed by systemd before it completes. It needs the -D option to prevent that.

It should read:

[Unit]
Description=Flush the dma mail transfer agent's queue
Documentation=man:dma(8)

[Service]
Type=oneshot
ExecStart=/usr/sbin/dma -Dq

ubuntu@srv-dyc64:~$ lsb_release -rd
Description: Ubuntu 26.04.1 LTS
Release: 26.04

ubuntu@srv-dyc64:~$ apt-cache policy dma
