Switching between email users is possible without any password or server settings changes, can u update a fix ?
Few days ago I have found a bug that can make problems for thunderbird users.
As i setup my account on thunderbird I have found that I can change email user ( sender ) with anything I want.
Ex. : My email is " mzolota@gs-tmt.com " now I can put " whateveryIwant@whateverIwant.com/net/ba etc. " without changing user password and server setting.
Is it possible that this is problem with my email server or its bug in thunderbird ?

As you set up an account? But doesn't it validate the email address when you complete the set-up?
There is a new "feature" in Thunderbird that lets you change the "From:" address when composing a message. I don't understand its value or usefulness myself.
In many cases, the use of such an address would prompt a warning or error message from the smtp server, or the server might silently replace the address with a valid one (I'm thinking of gmail here.)

I have to add "real" account first ( 'cause of validation ) but then I can change Name, FROM: etc. to what every I want. Is there any chance to "lock" the settings ?
Of course there is no option to lock the setting. The mail server does not care, or should not care what you place in that field, as long as the destination is correct.
Outlook and Gmail both validate the information and make unilateral changes to the information based on the user name signed into the SMTP server. But that is not what is supposed to happen.
I suggest you look up the term backscatter for email. That is when spammers use legitimate emails addresses for their from that belong to others and the trouble it causes the owner of the address. They get away with it because the email specification explicitly does not require that the reply to address, the from address or the abuse address actually resolve to anything or anyone. Nor does it require that the address in any way is associated with the server that sends the mail.
