i'm running qmail on slackware. we had a log file get a little out of control and ran out of disk space on the disk.

i corrected the problem, but qmail still thinks there's no disk space! i can receive mail, send local mail, but i can't send remote mail!

in my log files im seeing this a lot:

Nov 8 19:57:37 evo sendmail[21952]: hA90vbpq021952: to=postmaster, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=32985, relay=localhost.deadamerica.org. [64.235.47.3], dsn=5.1.3, stat=User unknown
Nov 8 19:57:37 evo sendmail[21952]: hA90vbpp021952: Losing ./qfhA90vbpp021952: savemail panic
Nov 8 19:57:37 evo sendmail[21952]: hA90vbpp021952: SYSERR(nobody): savemail: cannot save rejected email anywhere


it looks like it's saying there's no postmaster setup, but i have a /var/qmail/alias/.qmail-postmaster file setup (it's been there and working for months).

i tried restarting qmail completely. anyone know how i can fix this? it's kind of urgent, our users need to be able to send mail to outside domains.
