Phishing email from “Zimbra Webmail Team”

We’re seeing more phishing email aimed at Zimbra accounts.  This example came from a hacked account in Sri Lanka, claiming to be from “Zimbra Webmail Team”:

The idea is to trick you into entering your email address and password on the bad guys’ server so they’ll be able to hack your account.

Our Barracuda spam filtering blocks 99%+ of this stuff, but some still gets through.

Be on the alert for suspicious-looking messages.  This one wasn’t well done, but we’ve seen some that were pretty clever, with good formatting, logos, etc.

If you want to check your disk space on a Zimbra account, log on to webmail – you’ll see an indicator in the upper-right corner that shows where you stand in terms of storage allowance.

If you want to change your password on a Zimbra account, log on to webmail and click “Preferences”. links from quarantine email broken on some domains 3/11/2019 – Resolved

Update:  this has been resolved as of 11 AM EDT, 3/12/2019

Clicking the link in quarantine notifications in some Browsers (Chrome, Firefox) may take you to a temporary error page.  Logging in directly to works normally.

We’re working with Barracuda to remedy this.  In the meantime, log in directly to with your email address and password if you have any problems following the link from your email quarantine notification.

Phishing email – proceed with caution

Our multi-layer Barracuda spam/virus/malware filtering is very effective, but some bad things do slip through when the bad guys come up with new tricks and send email before the spam filters get updated.

Here’s an example that came in today, claiming to be from Chase and asking the recipient to correct something about their account.  When viewing the message on a computer you can hover the mouse over any links provided and see if they look real – in this case, doing that showed that the link actually went to a compromised server in Bosnia/Herzegovina:

When in doubt, don’t click on links in email that claim to be from your bank or an online merchant.  Log on to your account manually and decide whether any action needs to be taken.

There is currently an outage affecting our Sterling, VA facility, colocated with Centurylink.  The outage is being investigated.

Because of an issue with the server that hosts, we had to perform an emergency backup and restore Sunday afternoon, 11/12/2017.  This caused incoming mail for and addresses to go missing for a few hours.  We were able to re-deliver all of the missing mail, so no incoming mail was lost.  Depending on your email software, the Sunday afternoon email might appear out of order if your software lists the messages by time received rather than time sent, but it’s all there.

If you manually moved mail from one folder to another on Sunday afternoon, those changes reverted.  Your mail is all there, in its original locations.

If you have any filters set up to move mail to folders other than your INBOX as it comes in, those filters worked when the mail was redelivered and your mail is where you expect it.

If you sent mail Sunday afternoon using, your mail was sent but copies weren’t retained in your ‘sent’ folder.
