Hi guys, how can I set automatic message to reply every email, that comes to my mailbox for the time when I am on holiday. Is something like that possible in GMAIL?

I don't think that this feature is currently supported in Gmail. But you could always forward whatever messages you want to send automatic replies to (it's better to filter since sending vacation messages to mailing lists is really annoying) to some other mail service which does have automatic replies. The only one I know of that is free is fastmail.fm, but there are very tight restrictions on storage space and mail volume.

Personally, I have never used automatic replies since, for me, almost all mail can wait a few days.
