Re: Error code: CSFE_SVC_ERROR

Just to follow-up, it WAS DoSFilter. Following the wiki article was just the thing. Once I started looking at the right logs (in my case /opt/zimbra/log/zmmailboxd.out) I was able to pin-point which IPs were getting filtered.

Re: Error code: CSFE_SVC_ERROR

MisterM74, did you ever sort this out? Did changes to DoSFilter resolve your issue?

Re: Does fail2ban need iptables?

Lately I'm running into this (distributed attacks) as well. Very pesky because as you say DOSfilter isn't as effective if there's only one bad attempt per IP, but mailbox lockout policies can still kick in and then we get a call from a client wondering what's up.

Re: Staff Member Locked Out

Something is locking the mailbox: • How is the user accessing their mail? Web based, IMAP-client? Do they have a mobile device configured? Maybe they've got a device where they've simply haven't updated the password? • A lockout every hour could imply someone is trying to brute-force the account (W...
