imho, your issues are related to your config file, rather than all the changes in the software. Also, your DNS configuration and ipv4 reputation is a major factor today. Your ipv4 should be 'clean' http://multirbl.valli.org/ and your ipv4 should have forward/reverse and your sending domain should have SPF, etc etc. I am also running a very old version of sendmail, which I recently updated, In my case, I had to redo the config file completely and change many of my scripts I also have some Postfix and a few Exim, I like all of them and they have become like spanners to me... one is a 9, the other a 12 and you simply cannot exist without a 13 :) At the end of the day: Always remember to have fun!
