This is another issue I noticed after migrating to the new server:
Mail::Sendmail
Your server does not have Mail::Sendmail installed, or Mail::Sendmail requires another module that is not installed. This module is required for sending mail via SMTP Server. Please consult the installation instructions for help in installing Mail::Sendmail.
I renamed the mt-config.cgi file and ran the installation wizard (mt-wizard.cgi) again. The wizard successfully sent a test e-mail, so it must have found Sendmail, but the mt-check.cgi page does not reflect that.
