    • Note:
      – Below given description is based on the Google Apps customers.
      – Wrong settings may affect your email flow.
      – Refer all links and available documents before taking further action.


    Fight against SPAM and Spoofing with just 3 stage DNS changes described as below.

    Stage 1: Define proper SPF record

    Sender Policy Framework (SPF) is an attempt to control forged e-mail. SPF is not directly about stopping spam – junk email. It is about giving domain owners a way to say which mail sources are legitimate for their domain and which ones aren’t.

    • For Google Apps user its just simple TXT record can be updated in the DOMAIN DNS.
      – Record type: TXT
      – Host: @ or Empty
      – Value: v=spf1 include:_spf.google.com ~all

    If the same domain is used with other email servers like website query forms or bulk/mass mailing can be refer this help article: https://support.google.com/a/answer/4568483

    Kindly visit this link to access FAQ: http://www.openspf.org/FAQ

    Stage 2: Integrate DKIM to the your outgoing email.
    You can help prevent spoofing by adding a digital signature to outgoing message headers using the DKIM standard.
    Recipient servers can retrieve the Digital key to verify that the message really comes from your domain and hasn’t been changed along the way.

    • For Google Apps customer can add one TXT records to the domain and after authentication process Google will start adding a digital signature to the each outgoing email from Google Apps.
      – Record type: TXT
      – Host: google._domainkey or google._domainkey.domainname.com
      – Value: v=DKIM1; k=rsa; p=MIGfMA0GCS++++++++++++++++++++++++/+++++++++++++++++++/+++++++++++++++/+/3NIQIDAQAB

    To generate the key and configure for your Google Apps, kindly refer this help article: https://support.google.com/a/answer/174126?hl=en&ref_topic=2752442

    Kindly visit this link to access FAQ: http://www.dkim.org/info/dkim-faq.html

    Stage 3: Secure your domain from Spoofing with DMARC
    DMARC is an email authentication protocol. It builds on the widely deployed SPF and DKIM protocols, adding a reporting function that allows senders and receivers to improve and monitor protection of the domain from fraudulent email.

    • Once you complete above 2 stages you can deploy the DMARC to your domain to get best out of it.
    • If you are “single domain” company and using a single server can simply update the DNS records to avoid getting Spoofed
      – Record type: TXT
      – Host: _dmarc or _dmarc.domainname.com
      – Value: v=DMARC1; p=reject; sp=reject

    To configure DMARC for your domain you can refer this help article: https://support.google.com/a/answer/2466563?hl=en&ref_topic=2759254

    Kindly visit this link to access FAQ: https://dmarc.org/wiki/FAQ


    As Google Apps as the Google Group and SPF, DKIM and DMARC also affect the behavior of the email addressed to the Group Email address.

    Kindly refer this help guide for better understanding.

  • Set a local mailbox size with the registry

    1 February 2016

    Set a local mailbox size by setting a registry key

    By adding the following registry key and accompanying DWORD Value, you can limit the size of a user’s mailbox to a specific number of megabytes. This value also includes the size of delegated mailboxes that can be accessed. When you implement this registry key, the Mailbox Size Limit options are not available.

    Create the following registry key and accompanying DWORD Value on each computer where Google Apps Sync is installed:

    • Add the following registry key: HKEY_CURRENT_USER\Software\Google\Google Apps Sync\EmailSync
    • Modify HKEY_CURRENT_USER\Software\Google\Google Apps Sync\EmailSync by adding the following DWORD Value:
      • DWORD Value name: MaxStorePstSizeMegaBytes
      • DWORD Value data: Enter the number of megabytes that you want as the maximum size of the mailbox (for example, 256 for 256MB)
    • The Outlook has some default PST capacity as Outlook 2003 and 2007 can go up to 20GB and Outlook 2010, 2013 and 2016 can go up to 50GB.
      • To define more than the default size of the Outlook PST capacity you must update the PST capacity first mentioned in this help guide.

  • GASMO authentication issue with Google Drive disabled users.

    9 December 2015
    Comments are off for this post

    Users of Google Apps Sync for Microsoft Outlook (GASMO) version 3.8.430.1200 who also have the Drive service disabled will be continuously prompted to re-authenticate.

    How to diagnose:
    The Drive service will show as ‘Off’ on the affected user’s overview page within admin.google.com.

    When the user attempts to sync using GASMO the dialog box ‘Please sign-in to Google Apps Sync’ will be displayed. After successfully signing in the dialog will continuously re-appear.

    There are two workarounds:
    1. Enable the Drive service for GASMO users. To do so please see the Help Center article ‘Turn Drive on or off for users’ at https://support.google.com/a/answer/6115117.
    2. Disable GASMO Notes sync. To do so please see the Help Center section ‘Disable sync for a specific product’ at https://support.google.com/a/answer/1041455. Specifically the registry keys that should be created are the following:

    HKEY_CURRENT_USER\Software\Google\Google Apps Sync\DWORD:SyncFlagsEnabled with value 1
    HKEY_CURRENT_USER\Software\Google\Google Apps Sync\NotesSync\DWORD:DownloadEnabled with value 0
    HKEY_CURRENT_USER\Software\Google\Google Apps Sync\NotesSync\DWORD:UploadEnabled with value 0

    Note that if you are running a 32-bit version of Outlook on a 64-bit installation of Windows the registry prefix will instead be HKEY_CURRENT_USER\Software\Wow6432Node\Google\.

    Latest Update:

    Time: Wed, Dec 9, 2015 at 1:43 AM – The Google Apps product engineering team is currently investigating this issue.
