就是那个分解mbox文件的程序：
fpout = open( r'd:\a.mbox', 'r+' )
fpout.close()
fpin = open( r'd:\a.mbox', 'r+' )
iFileNum = 0
while 1:
    strLine = fpin.readline()
    if not strLine: break
    if strLine[0:5] == 'From ':
        if fpout:
            fpout.close()
        fpout = open( r'd:\pythonmaillist\%d.txt'%iFileNum, 'w+' )
        iFileNum = iFileNum + 1
    fpout.write( strLine )

fpout.close()
fpin.close()
