I kept plugging away and slowly but surely realized that nfsen needs a full
stop/start in order to re-read the configuration file changes. (FYI – an nfsen
reconfig doesn’t work)
So…there you have it.

What does /var/log/maillog have to say?

Hi all,
I’m at my wit’s end. Previously, nfsen was set up to use an external SMTP relay
(Postfix) and it worked fine. I installed sendmail locally, tested and
confirmed that it was functional, then switched over the $SMTP_SERVER to
‘localhost’. Once the change was made, nfsen could no longer send e-mails.
Ex.
$MAIL_FROM = ‘r...@host.example.com’;
$SMTP_SERVER = ‘localhost’;
I’ve tried multiple variations of the hostname, domain name, even replacing
localhost with the FQDN of the host itself.
sendmail is set up to allow connections from the local machine by default:
Connect:localhost RELAY
GreetPause:localhost 0
ClientRate:localhost 0
ClientConn:localhost 0
Connect:127 RELAY
GreetPause:127 0
ClientRate:127 0
ClientConn:127 0
/etc/hosts should be correct:
127.0.0.1 localhost
127.0.1.1 example.com host
I get an extremely generic failure message via /var/log/syslog:
May 4 14:45:18 flowtool nfsen[799]: Alert 'test_alert' condition == true,
condition counter: 1
May 4 14:45:18 flowtool nfsen[799]: Alert 'test_alert' execute action

May 4 14:45:19 flowtool nfsen[799]: alert 'test_alert' : Failed to send alert

May 4 14:45:19 flowtool nfsen[799]: Alert 'test_alert' Info : .
May 4 14:45:19 flowtool nfsen[799]: Alert 'test_alert' done.
Looking at my sendmail logs, nfsen (and by extension, nfAlert.pm) is not even
hitting sendmail. It’s failing somewhere else, but I can’t get any detailed
logs to help me along. I tried to redirect STDOUT in nfAlert.pm, but no output
was generated. I know outbound e-mail works since it’s fine with the external
postfix box. I must be missing something stupid, but I can’t find anything to
help me along in the mailing list archives or in general via Google.
I was hoping someone here might have some past experience with nfsen and
sendmail that would be willing to give me a hint.
Thanks!
