Use SpamAssassin with MailSweeper for SMTP

"Tooms" - a longstanding member of the Clearswift MimeSweeper forums, has published a comprehensive guide for integrating SpamAssassin with MimeSweeper for SMTP (version 5 upwards). This gives you such benefits as:

  • Plugins such as DCC, Pyzor, Razor, Fuzzy OCR
  • Award winning anti-spam engine
  • Well documented, many forums for support
  • Open Source (and free)

I would recommend a beefy server for this though, SpamAssassin is known for being somewhat greedy with system resources.

The guide is on Tooms's homepage - here.

Blackberry 8800

The Blackberry 8800 made it's UK debut a few weeks ago. At that time my company was in the middle of a negotiation for a large number of Blackberry 8700's, and as Vodafone had these devices straight after they were launched we managed to talk them into upgrading our order to a batch of free 8800's instead.


Blackberry 8800 and 8700

When I first installed it, BES 4.1 had initially annoyed me with it's move away from the classic MMC and redesigned interface (why did they disable right-clicks?) but using it to do a bulk device rollout was noticibly less administrative effort than on older BES versions. It was basically done in these steps:

  • Bulk add the users from the GAL
  • Create a new group (Blackberry group, not AD group)
  • In the BES console add all of these users to the group

You can then apply changes to these users all at the same time by applying them to the group - such as:

  • Setting activation password
  • Applying IT Policy

I created a simple IT policy for these users to show user information on the 'device locked' screen and to lock the devices after 60 minutes of idle time. They were also required to set a password with a minimum of 4 digits on activation.

Final step was then to:

  • Activate the devices

Instead of activating these devices myself, I wrote a quick guide to help them through the setup wizard and to let them know the activation password, and I sent it with the PDF version of the 8800 "Getting Started Guide". The only activation problems I had were a few devices that were not provisioned properly by Vodafone so would not activate - this meant a few calls to customer support (but I guess 5 out of 42 devices isn't that bad).

The devices themselves are pretty good, basically I would describe it as like a big Pearl with a few extra gimmicks thrown in - such as GPS and Blackberry Maps (which is a bit slow and US-centric). Size-wise they are actually a bit bigger than the 8700 but slightly slimmer, and the thumb board has been redesigned - the keys are now closer together and feel a bit more spongy rather than clicky. The screen is still good - nice and bright and fonts are easy to read. Overall though I think I do prefer my 8700 BB. It just feels the right size and I'm used to the spacing on the thumb board.

The biggest change on the 8800 is the move away from the jog wheel to the pearl-style trackball. It does work quite well but I do feel a little disappointed, the BB jog wheel is just iconic, and in some ways I think it's more precise - you definitely know when you have 'clicked' it from one position to the next. Anyway my users are happy with their brand new toys and happy users means less support calls!

Improving battery life on the Sony Ericsson K800

Sony Ericsson K800i3G is a great selling feature for modern mobiles, but are many people really using these 3G features yet? I certainly don't - I moved to Virgin Mobile when I got my K800 and unfortunately mobile web browsing is now too costly at £4 per Mb (with no option to add GPRS bundles), and I don't know anyone I can make video calls to yet. Another grumble I had after changing phones was battery life on my new phone was a bit disappointing. However, through a colleague at work I made a nice discovery - disabling the 3G features on your K800 can extend your battery life for another 24 hours. This is how you do it:

Menu - Settings - Connectivity - Mobile Networks - "GSM/3G Networks"
Change the option from "GSM and 3G" to "GSM Only".

The 3G icon will then disappear from your standby screen. You can always switch this back when needed or if all of your friends suddenly go out and buy video phones!
