Hello,

I'm trying to patch mailq... I want to change the output format

I added the "-batch" option to do the following:
- remove headers
- put every data about a queue item on a same line
So, the format in batch mode is:

size;qid;date;user;from;[status;recipient];[status;recipient];[status;recipient];[...];

So, excepted for the last line (I think I will remove it), I have a
CSV-parseable file.

The patch is attached.

I'd need your help:
- My queue is quite always empty. Could you provide me an output of
mailq command with and without "-batch" option?
- What's your feeling about this feature? How do you supervise your
mail queues?
- Bonus question: how to disable delivery process in order to fill my
queue by myself?

Thank you for your help :-)
Jerome Blion.
