Max, your list looks very similiar to what I'm seeing. I seem to have suceeded in removing all of the testing packages from my backup instance, now, just need to flip the ips around and see if the ship still floats.
The culprits that seemed to be causing the massive dependencies were libsasl2-2 and libsasl2-modules-db. Though not libsasl2-modules which i also have installed. Using apt to try and remove the first 2 were causing this: The following packages will be REMOVED: apache2 apache2-bin clamav clamav-daemon clamav-freshclam clamav-milter clamav-unofficial-sigs clamdscan colord curl dirmngr git gnupg gnupg2 gpg-wks-client libapache2-mod-php8.2 libapache2-mod-ruid2 libaprutil1-ldap libclamav11 libcurl3-gnutls libcurl4 libgphoto2-6 libldap-2.5-0 libmailutils9 libmemcached11 libpq5 libsane1 libsasl2-2 mailutils mongo-tools opendkim opendkim-tools python-apt python3-certbot-apache python3-debianbts python3-pycurl python3-pysimplesoap python3-reportbug reportbug sane-utils sendmail sendmail-bin sensible-mda I sucked down those 3 packages and downgraded them via 'dpkg -i' and was able to uninstall and reinstall sendmail by apt and now, no more packages from testing. Whew, I won't do that again. But it's good to know how these things work! Thanks all for your help.
