We use Google for our institutional email, and the Gmail interface defaults to that when I reply to a message. Looking at the existing Wheezy server which works correctly, I do not see anything providing an auth daemon besides saslauthd: # dpkg-query -W | egrep 'sendmail|sasl|courier|dovecot' libsasl2-2:amd64 2.1.25.dfsg1-6+deb7u1 libsasl2-modules:amd64 2.1.25.dfsg1-6+deb7u1 sasl2-bin 2.1.25.dfsg1-6+deb7u1 sendmail 8.14.4-4 sendmail-base 8.14.4-4 sendmail-bin 8.14.4-4 sendmail-cf 8.14.4-4 So I guess my question is, do I need one now on the Bullseye server, if saslauthd always worked for this before?
