This error message occurs when the delivery of an e-mail failed:

"This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:


  This email address is being protected from spambots. You need JavaScript enabled to view it.

    SMTP error from remote mail server after initial connection:

    host []:

    554 SBRS score too low: "

What does that mean?

The reputation (a value that determines whether emails of the server accepts or rejects) the mail transmission server is too low and therefore the e-mail was rejected. Therefore lands the sending server on a blacklist. Reasons for this may be that the sending client PC (tablet, mobile phone, etc.) is infected by a malicious program / Trojans or even the server itself.

What can you do?

One solution is to send the email on another account (,,, etc). Also recommended is to scan your own PC for malicious software. If the problem occurs only when the e-mail sent over the first used an email account and the IP of the sending server is on the blacklist, then speak with the service provider. If the error is there, the problem is usually resolved within a day, because the rating of "SBRS" is dynamically updated.

Is your Blackberry® Playbook not charging?

Because of the good price / performance ratio, many customers have opted for the "BlackBerry® PlayBook Tablet". The battery has a very good capacity, everyone who use it daily knows that. Thereby it can happen sometimes that we forget the warnings to load and while reading or surfing thoughtfully, collapses the battery.

Deep/total discharge - what now?

Symptoms and signs include:

  1. no reaction of charging LED on the annexes to the PC charging cable or the included AC adapter
  2. continuous illumination of the LED in red, then nothing and a periodic glow of LED in green / yellow

Try this

If you have, use the fast charger (available as an accessory) with 12V and 2A output. You should use that because of the higher output power. Just connect and leave them alone for about an hour.

The PC charging cable is not recommendend because the USB port just does not deliver enough power to get the battery out of its total discharge.

If you have only the supplied AC adapter at hand, it is advisable to turn the Playbook on after connecting the power supply and to put into standby mode. Do not get confused by the red dotted battery sign. Is the BlackBerry® PlayBook in standby, it recovers slowly back with the weak power supply, when it can load two or more hours at rest, too.

Tip: Deactivate Wlan!
