[SOLVED] SMTP Server Reported: 452 4.3.1 Insufficient System Storage

[DEpple]

Come Monday morning everyone in my office is receiving the following error when trying to send an email:

Zimbra Collaboration Suite could not send message: mail.SEND_FAILURE
Method: SendMSgRequest
Msg: SMTP Server Reported: 452 4.3.1 Insufficient System Storage
Code: mail.SEND_FAILURE
Detail: soap: Sender

We are suppose to have unlimited space so I don't fully understand why it would be telling me we have Insufficient System Storage. If anyone can help please do! Our entire office is without email and for some reason it always gets put on me to fix it!!!! Disclaimer: I am a newb who is willing to learn.

Do you server HDs have enough space on them? Can you go to a terminal and ssh into the server and run the following (for starters):

df -h

Are there any errors about lack of space in your server (operating system) log files? Are there any errors in the Zimbra log files when this happens?

[DEpple]

Thanks for the help phoenix!
I have figured out that we are using 95% of our HD space, which is confusing given we have unlimited space with Zimbra. I don't believe we should be storing any emails on our server.

Is there a way to check if we are storing them on our server instead of Zimbra's?

You need to check what files are taking up the space on your server, it may be files other than your email. Go to /var/log and see if there's any large files those directories. You can also check the /opt/zimbra directories for the space that's being used. Can you give me a brief run-down of what your server configuration is? Can you also tell me what you mean by 'you have unlimited space with Zimbra'? Is your server hosted somewhere?

I followed through with your suggestions as found backup files to be the issue. After simply removing the oldest ones, I have freed up enough space for us to send/receive emails once again. As a newb, I was under the assumption that our emails were being stored on a "zimbra server" and ours was a proxy. Apparently, we have an "unlimited quota" with zimbra, not "unlimted space".
I appreciate your assistance and I will mark this as solved!

You'll need to keep an eye on the backups in future, you may want to consider moving them to alternative storage off the server. You might want to take a look at your backup strategy and the growth of your storage requirements as a near-term project in case you really do run out of space.
