I just deleted a weekly email backup which is about 130GB into trash. I noticed there is an error message on the email server (OS X 10.5) saying connect(/var/imap/socket/lmtp) failed: connection refused.
Could this be due to the tmp or swap partition being full?
How do I check if the swap partition is full?
I know this is OS X but posting to Linux as the problem may be similiar in Linux.
