I see no problem from my system sending to an external address with a "." in the username. We're on 8.0.2.

I tried with Apple Mail and also on a PC via Thunderbird as well as the webmail.

I'm at a school system with about 800 users and I like to keep the mailbox size below 1G.

I run an IPTables firewall script that I wrote, but it sounds more like you had a user account with an easily crackable password or (like has happened to me SEVERAL times), a user gives their...

fdsk takes a while to check the drive(s). Be patient and all will be well soon, hopefully.

I would just do this :

You'll never see that one again (unless they change the...

Ok back again.

It looks like all is well. When I upgraded to 8.0 this weekend, the server reset it's "zimbraImapMaxConnections" back to 200. I increased that back up to 500 and haven't had a...

None of the above fixed it.

I re-uploaded the GoDaddy certs and thought all was well, but here we are about an hour later and I'm seeing hundreds of log entries in mailbox.log...

I upgraded to ZCS 8 on Saturday, and all seemed ok. Now that my users are back and hitting the server, I'm getting this error as well. Most accounts are not receiving any inbox information.

The upgrade ran smooooth.

I noticed the freshclam.log file had not been rotating with the other logs in the zimbra home folder, so I did a manual rotation, restarted zmantivirusctl and all is well now.

What an odd...

I've been trucking along just fine until last Thursday, then this error pops up for multiple accounts on my server to multiple accounts to that domain. All other mail flows like a river.

Probably the easiest thing to do is just delete and recreate the account.

That sounds like a good idea. Good luck.

Have you taken a look at the tmp folder to see who it belongs to, permissions, etc.? My stuff to follow.

When I did ours, I went from Mac OS 10.5 (32bit) to Ubuntu 8.04LTS (64bit) and it took a few tries on test boxes to get the steps right.

Hello John,

I'm a former OSX user. There was issue after issue until I moved our stuff to Ubuntu and haven't looked back.

On the Mac java issue, we just had to move our SIS database (Oracle)...

No tools other than mentioned already and keeping all the unnecessary services off and I run ssh on a different port (not 22).

Here's a couple of rootkit checkers I use often

rkhunter


sudo aptitude install rkhunter
sudo rkhunter --update
sudo rkhunter -c -sk

Just for kicks, do this.

Edit /etc/lsb-release

Change it from :

DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
