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.

If you use our email server software, MDaemon Messaging Server, and you've ever called our support team with issues relating to being unable to send emails, you may have noticed that we often perform a spam blacklist check. To perform these checks we use just one of a range of useful tools over at the mxtoolbox.com website. We've been using this site for several years as in addition to the blacklist checking you can also do things like query a domain's Mail DNS and SPF records, check whether the SMTP port is answering and even obtain an explanation of message header information. An essential tool to add to your favorites if you are a mail administrator!

I'm slightly concerned that the news of a virtual information blackout yesterday may have detracted somewhat from the REALLY big stories that were breaking. Yes, had you have been paying proper attention you'd have noticed two new product updates from our Texan friends over at developer Alt-N Technologies. Ok, so it's possible I'm overhyping these a fraction but if you're a user of either product they're worth knowing about all the same.
