thunderbird: "sender address does not belong to logged in user"
I just got a new e-mail-addrss from my university, where I am going to study.
I want to manage this email-address with thunderbird, which is already managing my old email-address. Receiving email works fine, but i can't send any email using the university's email-address. Thunderbird always tells me that the "sender address does not belong to logged in user".
What am I doing wrong?
