Service Alert: Outbound SMTP Server – Some Bounces

We’ve been working on an SSL issue with one of our outbound SMTP servers. During the process of running an upgrade, a few messages were bounced when they shouldn’t have been. If you have experienced this or your customers have reported the problem, please simply retry and they should go through fine. Apologies for any inconvenience caused.

Service Alert: Zimbra Server Upgrades

Starting on Mon 13th Feb, we will begin a series of Operating System upgrades to our Zimbra servers to onto the latest version of Linux in preparation for upgrading Zimbra to the latest version (8.7.1), the upgrades for which will follow a couple of weeks later.

This will, unfortunately, involve some downtime for each server and is not without its risks.

We anticipate that each server will be down for a period of up to 2 hours, but hoping to keep it to 30 minutes.

The planned schedule is as follows: Mon 13th 22:00 – zimbra004 Wed 15th 22:00 – zimbra003 Thu 16th 22:00 – zimbra002 As part of this work, we will be removing support for some weak or obsolete SSL ciphers to improve security levels.

This could affect some users still running old web browsers.

Please accept our apologies for any inconvenience caused by this.

Using MessageBunker with Gmail

Gmail archiving

A requirement of MessageBunker that we store the user’s credentials, encrypted of course, so that we can access their mailbox for archiving. Wherever possible, we look for alternative solutions that allow for improved security and privacy. Gmail offers one such solution.

MessageBunker can be granted a token by Gmail with the end-user’s permission, that needs refreshing hourly. This token can be used to log in. The process is known as ‘oAuth’ as is fairly common on the web, but this is the only implementation for IMAP that we are aware of.

When a user creates a new archive on MessageBunker, we send them to Google to give us permission to access their Gmail. We then get a confirmation back and a token we can use to log in.

The user does not need to reveal their password and can revoke our access to their Gmail account at any time, without the need to change their password, or alter any other systems that are accessing the account.

Old MessageBunker is dead, long live the new one!


Following on from our announcement at the end of September regarding the new MessageBunker interface and initial running of old and new versions in parallel, we can announce that, as of today, the old site has now gone – to be completely replaced by the new one.

MessageBunker gets a major upgrade!

The development team have been beavering away over some hot code again and we’re delighted to announce the launch of a new and improved MessageBunker email archiving, compliance and discovery service.

The updated service provides a brand new web interface, with statistics/graphs, lots of new help files, enhanced search facilities and a host of other improvements. In addition there is an all-new mobile site for smartphones that can be set up as a web app. too.

To really experience the improvements we’ve made please take a look at using your existing MessageBunker login credentials.

MailCore Pro Price Reduction!

For customers using MailCore Pro we are delighted to announce that, with effect from your first billing date on, or after, 1st October 2016, we are reducing the price of the full MailCore Pro feature set down to that of the ‘Basic’ – only £1 per mailbox, per month. Any ‘Basic’ mailboxes will automatically be upgraded to full MailCore Pro specification providing the option to use the collaboration tools if required.

In addition – and we know this is a ‘biggie’ for many of you – with recent upgrades to our CalDAV integration we now have a seamless Calendar integration with Windows 10!

Please note that it will take a while to sort out the back-end systems and merge them, so, for a short period, there will still be a separate ‘Basic’ version, but this will go and all mailboxes will be upgraded automatically.

Service Alert: Anti-Virus False Positives

We have been made aware that several users of our anti-virus email filtering are receiving what appear to be false-positive notifications as of this morning. These are affecting emails with attached .doc (and possibly other MS Office) files. The email in question is blocked and the sender/recipient (if hosted by us) will receive a notification stating a line similar to: /tmp/24007: Win.Exploit.CVE_2016_3316-1 FOUND. We are investigating this as a matter of priority. Although disabling your anti-virus will allow such emails to get through, we do not recommend doing this unless it is a very urgent matter. Services such as wetransfer and Dropbox may be used instead until we have resolved this situation.

UPDATE: We have now modified our virus signature databases to remove this false-positive detection. Apologies for any inconvenience caused. If you have advised a user to disable anti-virus we strongly recommend you reserve this as soon as possible.

Service Alert: Stats Update

We’ll be doing an update to the stats database this afternoon. This process will take around 30 minutes, during which time some stats might look a bit wonky. After the work is completed, stats should be quicker to display, particularly at the VISP level.

Service Alert: Issue with Control Panel Quarantined Email Viewing

We have an issue with this, which we are currently investigating. While we fix this, there are other ways to view the Quarantined email – simplest is to use Webmail to view the Spam folder.

EDIT: Now resolved. Quarantine folders can now be viewed as normal in the Control Panel. This was a minor code issue due to a service update yesterday. Apologies for any inconvenience.

Email Anti-Virus Filtering Upgrade

Today we have introduced a further level of protection our anti-virus service. Using our control panel, a third type of protection can be selected that blocks any incoming or outgoing emails containing Visual Basic for Applications (VBA) macros. These are typically found in Microsoft Office files such as .doc, .docx, .xls and .xlsx. Macros are small blocks of code embedded in the document to help with automation. However, they can also used as ‘payloads’ for transmitting malware and viruses.

To recap, we now offer three levels of settings: Standard Anti-Virus, Advanced (which includes phishing attack detection) and now Advanced with VBA Macro blocking. To use this new setting, users can select it from the ‘Protection’ section of their mailbox Control Panel.

This new feature is part of our ongoing commitment to improving our services and is provided to all customers at no additional charge.
