Hello, all. I recently upgraded from proftpd-1.2.0rc2 to
postfix-release-20010228. Coincidence or not, since then I've been
receiving a lot of "Postfix SMTP server: errors from *" in my mailbox
reporting a 452 Insufficient system storage when trying to receive mail.

        I set up a cron job to "df" my box every 10 minutes, because I didn't
believe I was running out of disk space. Last night I got 1600 <sic> error
messages from postfix, reporting disk space shortage, which the df output I
logged did not confirm.

        I'm pretty puzzled with that, I can't figure out what's going on. What
have I mislooked? I am sending the 2 message samples I received from
postfix and the df
output for the period.

        Thanks in advance!
