Sorry for my english(yoda english)

we have small issue about squirrelmail on web. I don't know whether it caused browser side or server side.
áwhen i logged in webmail in some account for sent mail everything is fine, so after logout (don'tclose browser) login some another account and sent mail our mail from address previous address.á

I think some kind of cookie or cache thing remains and mail sending different addres (especially reply mails)

any idea ?

thanks in advance
