You’re right, the Internet Mail provider could be configurated for Thunderbird.

avast does support more than one pop/smtp server. There is no restriction. That ones, the ‘default’ pop/smtp is used for another purposes (send files for virus analysys, etc.). Do not worry about that.

I suggest you make a search for ‘Thunderbird’ in the forums to learn more about the configurations.

Wellcome :wink:
