Thanks for your answer Bazsi.

Finally i got it.

Obviously I have used bad regexp. Exchange tracking log uses tabs as delimiters. But when I saved $MSG string to text log, tabs was changed to '\011'. 

So now I changed my regexp to use tabs as delimiters:

filter f_parsing {

This works like charm and saves first two tab delimited fields (date and time in this case) to $1 and $2.

I will wrote some HOWTO when i finish the configuration completely.

Thaks for your time.
