IMPROVED ANTI-SPAM WITH BAYESIAN ANALYSIS |
We've been promoting Mail Essentials for anti-spam prevention for a while, but the latest version now includes Bayesian analysis which absolutely decimates spam mail!
This is a must have product!
Current anti-spam techniques are largely static - relying on keywords and so on, meaning that it is fairly easy for spammers to evade them by simply tweaking their messages. The MailEssentials Bayesian filter is adaptive; it changes over time and learns spamming techniques, making it much harder to dodge.
Bayesian filters are widely acclaimed to be the best way to tackle spam and MailEssentials is among the very first products to implement this technology at server level in a reliable and effective manner.
In the first day of use in our own office the torrent of junk (over 300 a day) was instantly zapped to just 3. Since then we've maintained about a similar level, maybe half a dozen spam messages sneaking through.
We did get a few false positives - messages that should not have been trapped - largely newsletters which often have the look of spam. This is easily fixed through the "whitelist" mechanism.
Another great feature is that you can now direct spam to users personal junk mail folders - which means that they can review their own mail and decide whether to keep it or not. This is a great time-saver for administrators.
Another great tool for admins, outgoing mail is automatically scanned - recipients are automatically added to the "whitelist" of acceptable email accounts and the Bayesian filter is updated constantly as mail flows, giving more accurate results over time. All this with no admin overhead.
Other features include:
- Company-wide disclaimer
- Mail archiving to a database
- Reports on spam filtering and mail usage
- Support for DNS blacklists
- Fake non-delivery reports (NDRs)
- Foreign language spam detection
- Keyword checking
- Header checking
Finally, the pricing is very good, depending on users as low as £10 per user.

RE-ORDERING START MENU OPTIONS |
Did you know you can re-order options on the start menu just by click and dragging the item to where you want?
You can make a copy of it by holding down the Ctrl key as you click and drag.

RECOVERING CORRUPTED WORD DOCUMENTS |
It is pretty shoddy that one of the worlds most widely used pieces of software - namely MS-Word corrupts documents so frequently. It has been a problem from day one and the fact the Word-XP includes a "recover corrupted document" option doesn't say much for the current version either.
So, what are the causes:
1) Floppy disk corruption
2) Virus corruption
3) Slow network saves - though I haven't come across this, I have heard it being a suspect.
4) Document has tables or sections
5) "Allow Fast Saves" is turned on, turn it off, NOW! It is known to regular corrupt documents.
This corruption will show either as a partial document, or you can only scroll through it so far, or you can't open it at all.
So, what are the fixes?
1) Reboot the system and try again - maybe Word has just got in a twist.
2) Run a virus check
3) Copy the file in Windows Explorer and try the copy.
They may work, but I've not had a great deal of success with these. The following you should try entirely on the copy file.
4) Try saving the file in RTF format, open the RTF file and re-save in Word format.
5) Try using cut and paste to a new document. If you have sections, then cut each section separately and do not include the section break or the last paragraph marker in the section.
6) Try opening the file in Draft mode, not Print Layout mode.
7) Open the document in Word Pad
8) Try the "Recover Text" converter.
9) Use a third party reader, like KeyView or QuickView.
10) Use a recover tool, I've had good success with Word Recovery from www.WordRecovery.com
11) Try on a different computer, or a different version of Word (older or newer)
12) Set the default printer to a different type of printer, with a different print driver.
13) Try inserting the document into a new file.
14) Take a deep breath and understand you may have a lot of formatting, rekeying and proof reading to do…

ENTERING AND PRINTING THE EURO SYMBOL |
Well, the UK may not be a member yet, and the US won't be for at least 20 years, but that won't stop you needing to use the Euro - that funny crossed out E symbol
It looks like this € if your machine can display them.
Now keyboards are available with the symbol ready to roll, but if you need to enter it manually you can use this:
1) Make sure Num Lock is on (it usually is)
2) Hold down the ALT key
3) Type - on the numeric keypad - 0128
4) Release the ALT key
Now that should work anywhere, but there is also a more convenient shortcut:
AltGR + 4 for the UK
AltGR + 5 or AltGR + U for other locales
I knew that AltGR key was useful for something €€€€€€€

RUNNING LINUX PROGRAMS ON SCO OPEN SERVER |
Both SCO OSR5 and Unixware can run Linux binaries using the "lxrun" utility found on the Skunkware CD.
Generally you can also run OSR5 binaries on linux too. You will need the ibcs2 module. There are some places where problems may occur - SCO and Linux directory structures are different, you may not want to mix and match directories. Application calls to system utilities might need new links making or may use slightly different arguments.
Not a route recommended for large scale systems, but probably fine for smaller utilities.

UNIPLEX DATABASE FORM LIMITS |
Uniplex database forms have a limit of 255 fields per form. If you put more fields on the form than that then you will get the message "Too many columns in table". Strictly this does not apply to the "table", but the columns on the form.
There is no problem dealing with tables with more than 255 fields in a form as long as they are not all displayed in the same form.
This limit applies across the whole form, it is the sum of all fields on all pages of the form.

MOST USEFUL WORD SHORTCUTS |
1) Moving around:
Ctrl-Left or -Right Arrow move one word
Home and End move to start or end of line
Ctrl-Home, -End move to start of end of document
Ctrl-Up and -Down Arrow move up or down by paragraph
F5 takes you to the Goto dialog, where there are many possibilities. Once you've found the first item you can use Ctrl-PageDown or -PageUp to move to the next (or previous) item.
2) Moving and Selecting:
Using the Shift key while using the commands above extends your selection from your current cursor position to whereever the chosen command takes you, so for example, Shift-Ctrl-End, selects from current cursor to end of document.
You can also click on your start point, move to your end point and then shift-click to select everything in between.
Ctrl-A selects the whole document.
3) Tables:
There are some special variations for tables:
Alt-click selects a column
Alt-DoubleClick selects the table
Alt-PageDown, -PageUp goes to the bottom (or top) of the column
Alt-Shift-Up, -Down Arrow moves the current row up or down.

Haven't you ever wondered what causes supernovas?
