The BlackBerry Technical Knowledge Center has just posted a new support document entitled Unable to integrate a POP3 email account after changing messaging and collaboration servers.

This happens when, after messaging servers are changed, a BlackBerry device user working with BlackBerry Internet Service can't integrate or receive emails from a POP3 email account.

The document tells us that when a mail server is changed, it takes a few days for the DNS (Domain Name System) servers to update the IP (Internet Protocol) address.

Rather than just have you wait, this document (linked below) provides a five-step resolution.

I'm just about to tell you what those steps are.

While the instructions I cited for removing the "Sent from my BlackBerry Wireless Handheld" tagline does not work on the Pearl, BBHub reader and ardent ham radio guy David Kozinn provides this solution for performing that action on the BlackBerry Pearl.

"On the Pearl, go into the messages list, and press the menu key (the one to the left of the trackball)," David advises. "Scroll down to and select "Options," then "Email Settings" and make sure that "Use Auto Signature" is set to "Yes." You'll then be able to change your signature.

But then David adds an important point.

"Note that this procedure applies if you are using a corporate BES server," he writes. "If you\'re using a BIS server (i.e., you have an email address like someone@carrier.blackberry.net), you have to change the setting on their website."

In her Quick Fix column in the Wall Street Journal, Elizabeth Blackwell tackles a subject I don't recall that we've done here- nor any of the other BlackBerry-centered blogs and forums have either.

Her topic partially involves how to fix those "Sent from my BlackBerry Wireless Handheld" taglines at the end of your outgoing emails. Like the one I am showing you in that grab over there on the right.

This doesn't work on the Pearl but should on most other BlackBerry devices.

"To get rid of the BlackBerry tagline using the device itself, " Elizabeth writes, "go to 'Messages,' click on the dateline, which will prompt 'Options.' Select 'E-mail Settings,' then 'Auto Signature.'

Now you are ready to send your tagline away.

"You'll see the 'Sent from Blackberry' message in a text box," writes Elizabeth. "Simply delete it or type in a personalized signature instead>"

Last month the BlackBerry Technical Knowledge Center posted a very useful docoment entitled "Change The Default filter in your BlackBerry Internet Service Account."

I think this is a very useful primer for those BlackBerry users who wish to control which messages are forwarded to your BlackBerry device- and which are not.

Tell you what. If you have BlackBerry Internet Service 2.0 thru 2.2, you got a let up on them BIS 1.8 laggards.

First I will tell you about this procedure for BIS 2.0-2.2.

When you use the BlackBerry Gmail service to send messages from your BlackBerry device to another, they are stored in the Gmail Inbox as a conversation. They appear as new messages in the GMail Inbox.

But as the BlackBerry Technical Knowledge Center explains in a just-posted (and frankly a bit confusing) document entitled "Filter Messages sent from an integrated Gmail account," (link below) there's a way for you to create a filter that will prevent you from sending messages to or from a Gmail account on a BlackBerry device.

The document (which you can get to by clicking the Read prompt below this post) lists an eight-step procedure:

Bermuda-based Digicel, the largest GSM operator in the Caribbean, has just introduced introduced BlackBerry Connect for the Sony Ericsson P990.

Yes, the handset you are looking at over there on the right.

Nine of the carrier's 22 markets are involved in this rollout. We're talking Barbados, Bermuda, Cayman Islands, Aruba, Bonaire, Curaçao, as well as Jamaica, Trinidad & Tobago and Turks & Caicos; with plans to expand the offering across all of Digicel's 22 markets.

But in keeping with the song I may have planted in your head with this Post's title, no Kokomo.

Unless you are talking about Indiana, I guess.

Howard Forums Member limborepublic has trouble dancing under the bar on this one.

Based in the UK, limborepublic writes that his OS.67-powered BlackBerry Pearl stopped receiving emails about an hour ago. (I know that's a T-Mobile BlackBerry but that's how email looks on any Pearl.

"It just stopped receiving mail, even though it was still polling/searching and half a dozen mails arrived on my desktop," he writes. "I hadn't changed any settings - or even touched the thing, and the only way I could fix it was by turning it off and then on again, at which stage it worked just fine."

But limborepublic is not happy with those results. He's traveling (hmm, maybe to a warm tropical republic where they do the limbo?) Regardless (sorry, irregardless ain't no word) of whether or not he is traveling and where, the turning off and on is a bother, brother.

Ho-Foer gibbs thinks he may have the answer.

Many BlackBerry Enterprise Server administrators are familiar with the BlackBerry Enterprise Server Alert tool.

This tool can be used to Monitor Windows NT Event logs, and then send users a notification message whenever the tool senses trouble.

Trouble, in this case, would be a critical, error, warning, or informational event.

But for this to work, you need to configure notification settings on each BlackBerry Enterprise Server in your BlackBerry Domain or network.

A new BlackBerry Technica Knowledge Center document entitled User Guide: BlackBerry Enterprise Server Alert Tool shows you how to do that.

The two main sections of this document (linked below) show how to set the default monitoring level and then how to define a notification recipient.

Wireless communications company Dopod Inrernational Corp. and BlackBerry-maker Research In Motion said yesterday that BlackBerry Connect software would be available for 838Pro and C720W devices in Asia.

Both the 838Pro and C720W devices are HTC products.

Hong Kong, Singapore and Malaysia are the first three nations where BlackBerry Connect will be available for these devices.

On the BlackBerry section of Experts-Exchange, user akaSurreal (cool user name BTW) writes that when his BlackBerry Desktop Redirector semds messages to his company's Exchange Server, they keep on getting marked as junk mail.

As a result, the messages wind up in the junk folder and are never delivered. As a result, akaSurreal says, he's had to mark more than a dozen such messages as "not junk."

Well, that's a pain in the you know where. But one with an easy solution.

Comes from garicutri, who by votes of individual BlackBerry users on Experts-Exchange is rated this year's top BlackBerry expert.

Set your spam filter to low.

Barbara Ballard of Little Springs Design in Lawrence, Kansas writes a comparison review of BlackBerry email vs. the Gmail client.

And it isn't the BlackBerry email that comes out the winner.

"The problem was that I have discussion and news lists on my main email account, and the Blackberry doesn't (that I know of) have a filtering function," she writes. "Further, the generic BlackBerry client doesn't preserve some of the unique Gmail features, such as 'conversations', which created a good deal of cognitive dissonance."

Cognitive dissonance ain't cool, I might add.
