I have a debian box with postfix on it.
I checked the mailq and I do not understand how to read the mailq.
I need to know witch user is used to send this emails.
here is a example
0F87797868C 3993 Mon Mar 10 02:15:28 MAILER-DAEMON
(connect to unknown.interbgc.com[217.9.224.233]:25: Connection timed out)

(connect to mail.progys.fr[217.16.11.100]:25: Connection refused)
[email protected]
