Mail on Mac OS Server v10.13.4

I’ve been trying to get a new client on board and as part of that I’ve made a list of things that need to get fixed for that business to operate reliably. One of the dangerous things they are doing is running Mail Server on a Mac. This is about to become an unsupported config, so there is some urgency in getting a replacement service running. And of course the server was compromised, blacklisted and I’ve just spent nearly 3 days running around with my hair on fire. With most mail servers it’s a simple task to check the...

Phishing Grows Up?

This morning I got an email ostensibly from American Express, asking me to set up a ‘SafeKey’ to add an extra level of protection to my online purchases.   It looks legit. One of the first things I do is hover my mouse pointer over the supplied link- often the link will say it goes to Amex but the tooltip that appears when you hover says something like http://nastymalware.com/fakeamexsite.html and you know it’s fake. This one goes to amexssafekey.com (don’t click on that by the way!) That’s interesting,...

Stalking With iPhones

  Last week I was asked to go onsite and help a lady do some general maintenance on her laptop, and of course a bit of help with iCloud- because for some reason the way iCloud works isn’t well understood by the general public. I’m not immune to this either- they asked some questions I couldn’t answer without more research! Anyway, part of the job was to download some photos off old iPhones, then wipe them and get them ready for sale. She produced 3 iPhones and they all had very dead batteries except for the current one (in...

SSL Certificates in Mac Mail

We use an SSL certificate to increase the trust level around our email servers, one of the most important services we use! Unfortunately, to establish this trust, users are required to take some action when a certificate is renewed, or some host settings don’t match. This is one of the things that causes a huge amount of grief, and here’s why-   What’s the most obvious button to click here? You’d probably click ‘Connect’, and so would I. Don’t click ‘Connect’- it’s a trap!   You MUST...

Silent installs Using Meraki

*Just making clear that this post refers to the ‘legacy’ version of Meraki Systems Manager. There are some features of the paid version which make it a lot easier to install stuff remotely…. I’ve always known that we could install software with Meraki Systems Manager, but the need to pin the method down became a bit more urgent last month when our renewal for LogMeIn appeared. When I had first started using LogMeIn they had unlimited free clients, and you could pay for ‘Central’ to keep them all in nice...

VPS Maintenance

This post isn’t going to be very interesting for most people but it’s the results of a conversation I had online recently about what sort of maintenance to do for a VPS (Virtual Private Server). These things don’t require much manual help, but whatever you don’t watch will eventually fail, so I wanted to come up with some good strategies for preventing issues.   1. Reboot every 180 days. Yep, twice a year simply reboot the VM. Upon reboot, the machine will do a FSCK which should cover a few potential problems. 2. Know...
