Hi. Sorry for the lack of reply, but where things get tricky is I manage Moodle itself and a very small subset of the processes of the server (I work for an academic unit in at our college), and IT manages everything else.
I don't have much of a choice in upgrading. Much of the rest of the University is migrating to another LMS, which we've been given a year to do as well before we're forced to give up Moodle, so I don't see them upgrading anything in the future, unfortunately.
Also, as I mentioned, I have little control over the server. It is hosted in-house, running RHEL4.
1. I have no control over the admin mail account, or the mail server. I've asked them to forward me copies of these messages with headers in tact and got no response. (This is why I've waited a week to respond to your message... I was hoping they'd send me something.)
2. I disabled the email address on the admin account thinking it was a subscription email, but the emails came.
3. The failed login notifications were already set to nobody.
Are there any other places inside Moodle that I'm missing for notification? I set the support email under Server > Email to empty, even though that just looks like it's meant to be displayed for other users and not actually send anything out.
I am confident that it is actually coming from the moodle server because it only happens when the cron job is enabled, and I know the machine is firewalled securely that nothing else can get in. But, as I said, I'm awaiting info from our sysadmins to prove this as fact.
Thanks for the suggestions. I realize, without all the info, there isn't a ton you can do... hopefully I'll here from our sysadmins in IT soon.
