- So, I think I may have configured Postfix wrong...nothing is getting delivered, not even local mail from cron jobs. It's just sitting in the queue. (Postconf/postfinger and tl;dr at the end)
- Ubuntu 14.04.1 LTS
- While unfortunately it's been a while since I installed the server and I can't recall my exact steps, I do know I had attempted to (or did) set up ISPConfig on it, so if that helps shed any light on where I went wrong.
- The server, andromeda.gamefiar.com, is intended to mail out things to the internet periodically (user signs up, needs email confirmation, etc). I don't particularly care to get the output of the cron jobs (they were supposed to be redirecting their output to a log file anyway...), but mailing users on the forums who sign up, recover pass, or get an update to a subscribed thread, that's kinda necessary. And any stray output from a cron job really needs to get put in some kind of mailbox instead of hanging out in the queue clogging the tubes.
- I started moving stuff from my old server to this server today (it's not so "new" anymore, I set it up initially in Sept 2013 with one site) and I spotted some odd activity in top while I was monitoring progress of database imports and whatnot. showq (and other postfix-related processes) using up an exorbitant amount of CPU time, load averages in the 40s and 50s, etc.
- Hundreds of megs of logs (within minutes!) accumulating in /var/log/mail.log lead me to investigate.
- I did a postcat on some of the things I spotted in the mailq and there were all my cron job mails. The cron jobs were mailing the local account every time they ran (and I have a cron job that runs every minute, among others)
- So I just cleared out several. hundred. thousand(!) items from the mailq from almost a year and a half worth of it trying to mail local accounts, and boiled it down to just the 7 emails I'd really like for it to try to send.
- (One of them is a bogus address, the rest are real addresses, I masked them out as [email protected])

- -----------------------------------
- Note the (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)
- I was seeing this on pretty much every mail addressed to a local user with the @ (e.g. [email protected]) or to any internet user (real address).
- I did not see this connection refused line on anything that was addressed to simply "ruins" or "root" (no @andromeda.gamefiar.com). For all of that stuff, it was just sitting there in the queue and never ending up in any kind of mail directory like I'd normally see. Here's a sample of the queue before I cleaned it out:

- So, long story short:
- 1. Why is it seemingly not trying to deliver any mail (even local mail from cron jobs and stuff)?
- 2. Why is it trying to connect to 127.0.0.1 to deliver mail, and then refusing the connection?
- 3. How can I make it so that it will deliver local mail, so the output of a cron job ends up in the mailbox of the user who owns the crontab?
- 4. How can I make it so that it will deliver mail to the internet (or try to, at least)?
- Thanks <3
