Senders Email bounces because the gmail SMTP server address is blacklisted
A gmail account sender receives a notice that their mail has bounced because their IP address has been blacklisted by the recipient.
How can I fix this problem?
This is likely a temporary problem that happens only with some senders, so one option is to simply wait until the problem goes away.
Why is this happening?
Some domains might use a Realtime Blacklist service (RBL) to identify and block mail from suspected spammers. If enough of those domains' users mark mail received from a particular IP address as spam, the RBL can blacklist that address, blocking all mail from it. If your sender's mail is being bounced, it's possible that an RBL service has blacklisted their domain's IP address.
But my domain doesn't send spam. How did we get blacklisted?
Gmail sends mail from a number of different IP addresses that shift regularly. If one of your messages goes out from an IP address that was blacklisted after someone else used it to send spam, the sender's mail can start getting bounced. Mail bounces only from recipients who use the RBL that blacklisted that address, and only while the address remains blacklisted. Eventually, the RBL will delist the IP address, or Gmail will assign you another sending address, and your mail will no longer bounce.
What does Google do about this?
Google can't prevent RBL services from blacklisting any of their IP addresses if a domain is indeed using it to send spam. However, Google is regularly in touch with such services to ask that they delist the addresses when they do get blacklisted.
Introducing Windows 10
Windows 10 is full of new features and improvements. Take a look at the highlights by clicking this link

Windows 10 Features
Windows 10 is officially released. But what if you’re still using Windows 7 or 8? Should you upgrade (it's free) or should you stick with your current Windows?
I will focus on the major differences and features - this is not an exhaustive comparison.
Windows 10 vs Windows 7 and 8 – Performance
Windows 10 brings us several performance upgrades. The most noticeable is boot-up time, which is noticeably faster and general navigation feels nippier. With improvement in power management, mobile device battery life tends to be a little longer.
Windows 10 vs Windows 7/8– Design
Windows 10 uses the flat and bold styling. 'Flat' is the design theme of choice– you will see it on many websites. W10 relies on dark grey, semitransparent menus that look cleaner and more professional.There are some practical benefits to the new design direction such as smaller windows due to the lack of borders.
Windows 10 vs Windows 7/8 – Search and Start Menu
What does W10 bring to the table? Click on separate search box (on the taskbar) and it will include Windows Store apps and web search. Just clicking on the search box will show preview information such as the latest headlines, updates from your favorite sports teams and the weather, if you choose to turn these features on.
Introducing Cortana, your personal digital assistant. Cortana adds two key features. First - it monitors your email, calendar and search to provide useful information like when you need to leave for your next appointment (requires an app).
You can use Cortana to add appointments or make notes. If you have a microphone, you can speak your commands to Cortana. It does a decent job of interpreting natural language.
Cortana doesn’t return the answer to you in the search bar, but rather opens the web browser.
All this is combined with a Start Menu that now includes the Live Tiles from the Start Screen of Windows 8. Certain key features such as File Explorer and Settings are more clearly visible.
Windows 10 vs Windows 7/8 – File Management
With Windows 10 there are improvements to File Explorer. The top menu is now arranged in a ribbon, the common tools are easy to click and easy for novices to find.
There is also a new Share ribbon which makes it much easier to move files between different apps such as Outlook, Dropbox or Skype.
There is an improved file copying interface. Transfer speed is also shown in real time and operations can be paused. Previously they could only be cancelled.
Windows 10 vs Windows 7/8 – Notifications
Windows 10 has a single place for all notifications. This simple addition brings together system messages and app notifications into one place, with alerts ordered chronologically.
Windows 10 vs Windows 7/8 – Workspace Management
Windows 10 adds virtual desktops and better multi-monitor support.
With Windows 10 both these features have been enhanced. Different monitors can now have different backgrounds.
The taskbar can now appear on multiple monitors or both your primary monitor and whichever monitor you’re currently active in. Snap has also been improved to support snapping to four corners, not just side to side.
Perhaps the biggest addition, though, is virtual desktop support. Although Windows 7 has had support for virtual desktops via third-party software, now it's built right in.
Windows 10 vs Windows 7/8 – The Verdict
There's nothing wrong with sticking with Windows 7, however note that Microsoft will only support W7 until 2020.
Windows 10 has a lot of genuinely useful new features, as well as key improvements to old features, compared to Windows 7 and 8. None is enough on its own to make an upgrade necessary, but when combined they do make a compelling case.
Better search, window management, dual monitor features, virtual desktops and file management plus Windows 10 is faster in general use and the new Start Menu is better than Windows 8.

How to Protect your Office, Company or Organization
In recent months several of our clients have received email requests to wire transfer funds. This confidence scheme is highly targeted sending the fake wire transfer emails to employees working in the finance department of a company.
How it works
This con uses sophisticated social engineering to convince specific executives and other individuals with access to their company's accounts to initiate a wire transfer of large sums of money.
In this attack, the scammer not only knows the target's name and email address, but also the name and email address of someone else in the company whom the target might trust. The scammers have registered email domains that are very similar to the recipients' (for example: xyzwigdets.com instead of xyzwidgets.com) and send the email from the fake domain.
So, instead of coming from email@example.com, the email comes from firstname.lastname@example.org. The scammers are betting that some people won't notice the slight difference in spelling and thus won't suspect anything.
A Slow Con - No Dollar Amount at First
This is an old-school trick we don't often see in email scams. The scammer cons the victim slowly, first gaining their trust and then moving in for the kill.
In some of the emails, the first message is not only ordinary, it doesn't even request a specific amount of money. It merely asks to initiate a wire transfer today. The recipient, thinking it's coming from a co-worker who might ask for a wire transfer, replies to the scammer, who then engages in a brief email exchange, eventually asking for a specific amount. The scammer even confirms the money went through, probably to prevent the victim from becoming suspicious and reversing the transfer.
Why doesn't our Spam filter catch these?
This is a different type of threat. With its low-volume (only a handful of emails out of millions) and targeting of specific people, this dangerous campaign has few of the typical markers of spam.
Why is this scam so successful?
The people perpetrating these frauds frequently research employees’ responsibilities so they know who to target, and often gather information to try to make the wire transfer request as believable as possible. For example, they may research the executive’s schedule using public information or by making inquiries of the executive’s assistant with the goal of sending the fraudulent emails when the executive is out of town and cannot be easily reached for verification.
Although some of the fraudulent requests are for millions of dollars, they can just as often be for smaller amounts. Since many companies have stricter controls (like dual approvals) for amounts over a certain dollar threshold, the scammers often submit requests for lower amounts hoping the looser controls will raise the success rate of their scam. If the scammer is successful in a preliminary request, they may continue to submit additional requests until the scam is detected.
How to Protect Yourself and Your Company
Implement a Strong Policy: Security and Fraud Prevention begins with a solid set of policies and procedures. A company policy should include confirmation on any wire transfers. Train everyone at your company based on your policy. Keep your staff up to date on the latest threats.

What is Clutter?
Clutter is an email filtering option available to Office 365 customers. It is similar to an anti-spam filter as it moves less important email (based on your reading habits) into a 'Clutter' folder where they can be ignored or reviewed later. Most of the mail going into the folder should be bulk mail (advertisements) and messages from mailing lists. However, you will want to periodically check the Clutter folder as it may move legitimate email into this folder.
Individuals can choose to disable Clutter if desired. To disable Clutter log into https://mail.office365.com, click on the Gear, Options, Automatic Processing, Clutter and select Don't separate items identified as Clutter then click Save.
You can easily move mail between your Clutter folder and your Inbox. Note that Microsoft does not give us any options on what should or should not be Clutter.
Silloway Support can disable Clutter for all of your mailboxes (the Tenant) or use the instructions above if you wish to disable it just for your mailbox.
We are evaluating Windows 10 upgrades on a case-by-case basis.
Business users are faced with a variety of software and hardware that may or may not be compatible with the Windows 10.
SILLOWAY TECH TIP #1 – if your computer is 4+ years old we recommend not upgrading. Wait until you purchase a new computer which will arrive pre-loaded with Windows 10.
