Hi Marvin, Thank you for your reply.. that matches what I see. I had not realized recommends were installed by default.. I was wondering how those and suggests differed but hadn't gotten to looking it up yet. I had not used --no-install-recommends, simply 'apt install postfix' and libsasl2-modules was not installed. Looking at /var/log/apt/history.log, I see: | Start-Date: 2026-03-20 22:30:11 | Commandline: apt install postfix | Requested-By: greg | Install: ssl-cert:amd64 (1.1.3, automatic), postfix-lmdb:amd64 (3.11.0-4, automatic), | libcdb1:amd64 (0.81-2+b1, automatic), libicu78:amd64 (78.2-2, automatic), | postfix-cdb:amd64 (3.11.0-4, automatic), postfix:amd64 (3.11.0-4), | libtlsrpt0:amd64 (0.5.0.-1, automatic) | Remove: exim4-config:amd64 (4.99.1-1), exim4-base:amd64 (4.99.1-1), | exim4-daemon-light:amd64 (4.99.1-1) | End-Date: 2026-03-20 22:30:22 The following day, it shows that I ran 'apt upgrade' and libsasl2-2 was upgraded, but not libsasl2-modules (which appears to have matching versioning). I have to conclude that libsasl2-2 must have already been installed, without libsasl2-modules, when I installed postfix. Does that make sense? Since it was not installing libsasl2-2, the recommends: libsasl2-modules was not considered, only the postfix package suggests: libsasl2-modules. Maybe it would make sense for postfix to directly recommend: rather than suggest: libsasl2-modules?
