I recommend a codeplex project:
"File Operations For MSSQL, A SQLCLR Assembly" -> http://nclsqlclrfile.codeplex.com/
And after you manage to install this assembly, use the function:
DECLARE @FileImage varbinary(max)
SELECT @FileImage = dbo.MFGetFileImage('C:\stuff\email','bigemail.eml' )
SELECT CAST(@FileImage AS [xml])
You'll get likely get long lines of whatever and you can do what you want with them. Without abbreviations.
