Was your email falsely being detected as spam over the weekend?

We have received several reports over the weekend that customers email has been flagged as spam by some receiving mail servers.

Bounce backs included errors such as:

<– 554 The IP Address of the sender (1.2.3.4) was found in a DNS blacklist database and was therefore refused.

<– 550 Email blocked by bl.spamcop.net (in reply to RCPT TO command)

On closer investigation it appears there was a system outage at the Cisco SpamCop DNS-based blocking service and the underlying cause was that the spamcop.net domain name had failed to be renewed.

More information on this issue can be found at the following link:

How to Receive Email Alerts from MailStore if an Archive Job Fails

Will MailStore alert me when a job fails?

Of the many queries I see as a member of the MailStore support team here at Zen Software, this is one of the more common ones.

Unfortunately, for the time being at least, this isn’t something you can do from within the software but fear not – the reason for my post is that there is a workaround.

EDIT: Email reporting was introduced in v10.1 – more information here.

The Top 8 Antivirus Issues That Catch Our Customers Out

With the recent Panda Antivirus signature problem still fresh in my mind, and as a fair few of our support calls continue to be antivirus related, I thought you might find it useful if I share some of the antivirus issues we see regularly tripping customers up.

Of course every software vendor professes their product incorporates the latest and greatest protection technology. When you’re working out what to use as a Systems Administrator however, it’s also important to think beyond that and specifically about how your proposed solution will interact with other applications in your network environment.

These are a handful of the areas we find usually end up resulting in a support call.

Support queries shared: Rsync backups to QNAP failing

If you’re not already familiar with Rsync, it’s the method (or ‘protocol’ to be posh about it) that BackupAssist uses to send data off-site to locations such as NAS boxes or to other servers.

QNAP make a NAS device that’s popular with our customers and this week I came across an issue with backing up via Rsync to it that I’ve seen before…

…cue helpful (hopefully) blog post!

Support queries shared: MDaemon SSL errors – Windows XP and Server 2003

It’s a bit of a niche technical one this but as I’ve had several reports of it recently I wanted to share this one with you in case it helps.

If you’re an MDaemon customer you may have started to see the following errors in the SMTP (Out) logs when trying to send email to some specific external hosts…

“SSL negotiation failed*,*error code 0x80090326”

What this boils down to is an issue where MDaemon and the remote SMTP server cannot find a common set of SSL ciphers that they both have available to use.

Support queries shared: Office365 aliases and archiving with MailStore

MailStore and Office365As Office365 and other hosted Exchange platforms continue to attract more users, we’re starting to see more demand from customers looking for a way to keep an offline copy of their data ‘just in case’ the unthinkable should happen.

MailStore is perfect for automating this process, and while there’s a good setup guide online to cover the basics, last week a customer called in asking for help with the more ‘niche’ requirement of setting up MailStore to archive email going to aliases in O365.

Spike in virus infected emails – take extra care

We’ve seen a sharp increase today in new virus variants getting through to email users due to the speed at which they’re evolving to avoid detection.

Identical messages can arrive sometimes minutes apart but already containing different variants of the virus, making it a game of cat and mouse for the security vendors to keep up.

The fake Amazon order confirmation complete with suspicious-looking ZIP file is the one we’ve heard a lot of reports about but I should stress these emails change by the minute so it’s worth just thinking twice before you click links or open anything resembling an attachment.
