Hi ! Today I had run into low disk space condition, and found that we have been badly spammed Code: find / -type f -printf "%s\t%p\n" | sort -n | tail -20 reveal a LOT of same files of *same* size like: 134203542 /var/vmail/mydomain.com/*user*/Maildir/tmp/1606566109.M683566P25648.mail I have removed them manually, since these commands don't clean this stuff. Code: doveadm expunge -A mailbox "*" all postsuper -d ALL I think its a bogus archive which freeze unarchiver when Amavis try to scan its content. Anyone had such problem before? Is there any way to purge ALL mail tmp except Code: rm -Rf /var/vmail/*/*/Maildir/tmp/ PS. Additionally, there is huge 140737477881856 /proc/kcore But I don't think its a real file.
