When my Subversion post-commit hook tries to send an email, I get this error:
SMTP Error: Insufficient system storage
When I try to send a test email from Mutt, I get this error:
postdrop: warning: uid=2290793: No space left on device
sendmail: fatal: arthaey(2290793): Error writing message file
But when I check the panel, it says my mail account is using 947 MB of 520192 MB. My overall disk usage is only 946.9 MB of 508.0 GB. So I'm nowhere near the limits.
What's going on?
