Question: What was the email system released by the owners of the Perkins Estate in the 1980s called?

<P0-S0> The Perkins Estate is a historic estate at 450 Warren Street in Brookline, Massachusetts. <P0-S1>  The property was part of the summer estate of the Cabot family, originally belonging to Thomas Handasyd Perkins; the present main mansion house was built in the 1850s to a plan by Edward C. Cabot for his sister-in-law, Elizabeth Perkins Cabot. <P0-S2>  The grounds of the property were originally designed by Perkins, and subsequent generations maintained the grounds to a high degree. <P0-S3>  In the 1980s it was owned by Mitch Kapor, founder of Lotus Software. <SEP> <P1-S0> cc:Mail was a store-and-forward LAN-based email system originally developed on Microsoft's MS-DOS platform by Concentric Systems, Inc. in the 1980s. <P1-S1>  The company, founded by Robert Plummer, Hubert Lipinski, and Michael Palmer, later changed its name to PCC Systems, Inc., and then to cc:Mail, Inc. <P1-S2>  At the height of its popularity, cc:Mail had about 14 million users, and won various awards for being the top email software package of the mid-1990s. <SEP> <P2-S0> Lotus Software (called Lotus Development Corporation before its acquisition by IBM) was an American software company based in Massachusetts. <P2-S1>  Lotus is most commonly known for the Lotus 1-2-3 spreadsheet application, the first feature-heavy, user-friendly, reliable and WYSIWYG-enabled product to become widely available in the early days of the IBM PC, when there was no graphical user interface. <P2-S2>  Much later, in conjunction with Ray Ozzie's Iris Associates, Lotus also released a groupware and email system, Lotus Notes. <P2-S3>  IBM purchased the company in 1995 for US$3.5 billion, primarily to acquire Lotus Notes and to establish a presence in the increasingly important client–server computing segment, which was rapidly making host-based products such as IBM's OfficeVision obsolete. <SEP> <P3-S0>  Modifications fixed the Notes to proper lower interest, escrow, tax fees that staff typically raised for no reason. <P3-S1>  It was in 2009 that HARP, HAMP and Modifications were introduced to stop the victimization of Note Holders. <P3-S2>  While such scams were addressed through modifications in 2008. <P3-S3>  This money Note Holders were unaware of is the prize of real estate and the cause of the Real Estate Crash of 2008 where Lending Institutions provided mortgages to people years prior they know they would eventually loose with Loan holders purchasing Balloon Mortgages lending product that is designed to make fast money off the note holder whom is always typically unaware of their escrow, equity and that are further victimized by conferences and books on HOW TO MAKE MONEY IN REAL STATE - when in fact the money is the Note Holder. <P3-S4>  that collect the Escrow that is rightfully the Homeowners but because most Homeowners are unaware of what money is due them and how they can loose their escrow. <P3-S5>  Thus the birth of Modifications. <P3-S6>  It is yet to date for clarity how theses enforcements came into existence and except b whom, but t is certain that note holders form the Midwest reached out in the Democratic Process for assistance. <P3-S7> Loan modification is the systematic alteration of mortgage loan agreements that help those having problems making the payments by reducing interest rates, monthly payments or principal balances. <P3-S8>  Most Creditors are unaware that as the note holder that the Note Holder are due a annual or semi annual equity check and again bank or other lending and or legal intuitions staff claim this monies instead. <P3-S9>  Many were incarcerated for such illegal actions. <P3-S10>  Many people from various arenas involved in reals estate have been incarcerated for these actions as well as other illegal actions like charging for a modification. <P3-S11>  Lending institutions could make one or more of these changes to relieve financial pressure on borrowers to prevent the condition of foreclosure. <P3-S12>  Loan modifications have been practiced in the United States since The 2008 Crash Of The Housing Market from Washington Mutual, Chase Home Finance, Chase, JP Morgan & Chase, other contributors like MER's. <P3-S13>  The key of the crash was not the House, but the loan product used and the interest and money that was accrued form the note holders that staff too immorally. <P3-S14>  During the so-called "Great Recession" of the early 21st century, loan modification became a matter of national policy, with various actions taken to alter mortgage loan terms to prevent further economic destabilization.
