Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

For mass mailbox backups in Exchange, you should be using a proper backup and recovery system. See my post, PSTs are not reliable for that purpose.

It’s been over a month into 2017, and there is already a sophisticated Gmail phishing email making it rounds. New techniques and tactics, have given hackers a way to authentically impersonate your contacts.

How it Works


fake gmail login screen- phishedThe attack works by targeting a victim’s contact list and sending out authentic looking phishing emails. When this forged email is opened and the attachment clicked, a page appearing to be the Google log in portal opens.

Once the victim submits their credentials into the site, the hackers start crawling the victim’s inbox. These crawlers look at previous subject lines and attachments for contextual relevance to copy.

A screenshot is taken of a previous attachment and a new message is composed. This screenshot becomes the entry way into the phishing Gmail login page. The subject line is then pulled from a previous email that would be relevant to the attachment.

The new version of the email is sent to all the victims contacts, and the attack starts again. The use of previous subject lines and attachment, help to make the hacker’s email look very genuine. This technique has tricked many users into opening the infected attachment.

One of these emails is described by a commenter on Hacker News,

“[The hackers] went into one student’s account, pulled an attachment with an athletic team practice schedule, generated the screenshot, and then paired that with a

Many thanks for sharing the story here.

So with the new Exchange Server 2013, are you going to use DAG with lagged copy or just 2 nodes DAG only ?

In my previous company I was using 2 Nodes stretched CCR cluster across two different VLAN/Subnets geographical locations. It wasn't ideal since the AD sites is also different, hecne in the DR I must change the Mailbox Server AD sites membership to match the HUB/CAS server to be able to send email after the failover.

Microsoft Suggest 2 node CCR cluster  within the same AD site and then one more node to become SCR (standby) in the other AD site.

I am still evaluating our options with Exchange 2013 being drastically different than Exchange 2007.

The project is being significantly delayed by the existence of legacy messaging systems (like Exchange 2003) and the probability of a Windows Domain name change. [Which isn't exactly supported]

May the adventures continue.  :^)

Microsoft has released various new features which are capable of handling various tasks. One of these tasks is ‘Migration from pop3 to Exchange Server’. Pop3 data stores various data along mailboxes like contacts, tasks, etc. So, it becomes the need of the users to migrate pop emails to Exchange.

Why Migration
 
  • Due to some database errors, troubleshooting problem occurs with existing mailboxes.
  • Also,  managing database becomes so hard.
So, this blog will provide you instructions on how to migrate mailboxes from pop3 to Exchange. This procedure may be summarized in very few simple steps. The Steps include:

1. Creating a Mailbox in the Exchange Database,
2. Import your .PST file in that folder using a mailbox import command in Exchange,
3. Configure it with Outlook.

In this blog we are going through the entire migration process. First of all, we’ll start with creating a new folder in Exchange database.

1. Creating Mailbox in Exchange Database

As we know that the .pst files are used for pop3 account or can say pop3 uses .pst file extension. This .pst (personal storage table) files stores all your messages & other items & is being kept on computer only. So when you want to migrate pop3 to exchange, you need to import this .PST file to Exchange. But, this is not possible directly; for this you have to create a Mailbox in Exchange Database. Thereafter, you can easily transport .pst file to Exchange.

2. Importing .PST file to Exchange

Automapping, a wonderful feature with Exchange 2010 (SP2 onwards I believe), allows additional/Shared mailboxes that a user has access to be automatically mapped on Outlook client, simplifying the process by adding them while Outlook launches.

However, this may not be an advantage all the time especially if a user has full access permissions to many other mailboxes. All of those additional mailboxes will need to be mapped and opened when Outlook is opened. It will definitely take time to load all the mailboxes and hence will cause performance issues.

1-Before-change-AllMailboxesMapping.png
There are other problems too. I’ll discuss one issue I personally faced: A user having access to multiple mailboxes.
  • Outlook looks to be in connected state, but the folders are not updated.
  • Send will work, but receive will not.
  • On restart, Outlook tries to sync initially, but stops syncing in the very next minute, as there are limitations on the number of objects that can be loaded.
2-Outlook-Not-Syncing-As-the-object-limi 
You’ll see the event 9646 filling whole event log on the mailbox server hosting the user's mailbox.

3--9646-error-on-the-mailbox-server-host 
4--9646-error-in-detail.pngYou may increase the MapiSession limits to have this suppressed, but at the cost of Exchange's and the Outlook client’s performance.

MS outlook is a premier email client that enable you to send and receive the e-mails with various file formats of attachments such as document files, media file, and many others formats. There is some scenario occurs when a receiver of an e-mail message encounters an error at the time of opening  or saving an email attachment in outlook. Microsoft outlook pops up an error that is  “Cannot create file: file name. Right-click the folder you want to create the file in and click Properties on the shortcut menu to check your permissions for the folder”.

You know that you are fully authorized to access this attachment as you have previously opened such attachment from the concerned sender. So what was the reason of this error? Here we will discuss the possible reasons and provide methods to resolve this error.

First of all you should know how the entire process is working behind the opening of outlook email attachment file.  A temporary copy of an attachment is created when you open email attachment of outlook and stored in secure folder “Outlook Secure Temp Folder” on your computer. This folder is a hidden folder you cannot browse it in window explorer until you know the correct path to it.

Outlook secure temp folder stores a temporary copy of email attachment that has been deleted when you close outlook. But if you close outlook without closing the opened attachment then the copy of attachment will not be deleted from secure temp folder. This copy will remain in
