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[184.108.40.206]:25: Connection timed out) firstname.lastname@example.org 0273E9786EF 3421 Fri Mar 7 09:13:01 MAILER-DAEMON (connect to mail.progys.fr[220.127.116.11]:25: Connection refused) email@example.com
I am not sure but I suppose that this are bounces from spam emails.
How can I verify this.
