Fake base64 by Zabbix looks like "aZA Z09==" or "aZA Z09 aZA Z09" instead of "aZAZ09" or "aZAZ09=="

For some reason it adds spaces (double spaces) to the base 64 strings before sending it via e-mail.

Some tools (like Outlook or Notepad++ TextFX Tools Plugin) can decode these strings, but other tools (for example which use PHP base64_decode function - can't, which make these scripts and tools useless.
