Hello, I've set up a local mail server with Postfix 2.3.3 and Dovecot 1.0.7 on CentOS 5.2.
This is the first time I've used Postfix. I can send and receive local mail which, for the moment, is fine. When I tried to send a mail to an external mail address, the delivery failed, but I did not get a mail from the server notifying me of that. Using "mailq" I can see that the mail is languishing there: (connect to alt1.gmail-smtp-in.l.google.com[209.85.163.27]: Connection timed out) I'd like to know why I didn't get notified. According to http://www.postfix.org/bounce.5.html: "The Postfix bounce(8) server produces delivery status notification (DSN) messages for undeliverable mail, delayed mail, successful delivery or address verification requests. By default, these notifications are generated from built- in templates with message headers and message text." I'm presuming that means that, without adding anything to /etc/postfix/main.cf, that I should be getting some kind of notification about the mail problem from Postfix. Have I misunderstood this? If notifications are sent by default, I need to discover why I didn't get one. Any help would be much appreciated. I'd like to know within about 5 or 10 minutes if there is a problem with a mail I've sent. Thanks Ian Masters
