qmail receiving emails error
I have problems receiving emails. I get this error message:
Hi. This is the qmail-send program at mail.boxdomain.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
can not open new email file errno=28 file=/usr/home/vpopmail/domains/boxdomain.com/paranoix/Maildir/tmp/1146658478.6519.mail.boxdomain.com,S=2849
Please advise what I should do as this is the first time I'm getting such error.
