You may have picked up in the IT press recently that we're starting to see an industry-wide movement to a new, and importantly more secure, standard of SSL certificate.  Alt-N Technologies, developer of the Exchange alternative MDaemon Messaging Server have just announced they too are following this trend and stating they'll be replacing all end-point and intermediate server certificates with those based on the new SHA-2 algorithm. Important note: Alt-N will be moving to SHA-2 SSL certificates on January 20, 2015.

We recently needed to migrate our own internal MDaemon and SecurityGateway server to a new location. Luckily we often do this for customers and we have guides specifically written to help with this process. Migrating MDaemon Migrating SecurityGateway However one of the areas which we felt we haven't documented before is how to also migrate an existing SSL certificate that was being used by multiple services in these products.

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.

Over the last few months we have had an increasing number of support calls that relate to failing SMTP connections over Internet connections. This can happen on a range of network connections, whether it's mobile devices on 3G or home users trying to access their MDaemon mail server. Even businesses can find that they can no longer create outbound SMTP sessions on port 25 on their office broadband connections.

One of the most notable changes visually in Windows 8 is the range of new apps that now appear on the "Start" page. In a similar vein to mobile devices, there are email and calendar apps which now integrate tightly, offering handy features such as notifications. It's easy to see why some users will end up switching to this as their preferred method of access, so in this post I'll show you how to configure MDaemon to synchronise with these two key apps.
