Some comments that I think are relevant... Since it took a while for someone to respond to your question it tells me that it is a combination of tools that not many people are using. You are using sendmail in combination with systemd. That is an unusual combination. If it were widely used then many people would have been responding already. Frankly you might be one of the few trailblazing that combination. Trailblazers are great! They are the ones who make things happen. However not everyone wants to be a trailblazer. There just isn't enough time for everyone to do everything. You sound like a busy person without the time to debug everything. Perhaps it would be good to change to a more mainstream combination? If it were a mainstream combination then the problem would almost certainly already have been seen and fixed. Something with a lot of users and a lot of support. In this case I would suggest that Sendmail is no longer the mainstream mail transfer agent. Instead I suggest migrating to Postfix. (Or Exim but I personally really prefer Postfix so will recommend Postfix.) Postfix is well tested and very well supported. There has been discussion of making Postfix the default mta on Debian. (But that will never happen because Exim isn't bad just not as popular.) Since you are using Sendmail I assume you have been using Sendmail forever. You probably have multiple editions of the O'Reilly Sendmail book on your bookshelf. You probably hate to take the time to migrate a working configuration tuned over decades to something different. I have been there and glance over at my two remaining editions of the O'Reilly Sendmail books on my bookshelf. Let me say that moving to Postfix was very easy. I don't even have one copy of the O'Reilly Postfix book. It has an easy to understand design and the online documentation is excellent. I have been where you are with Sendmail and migrating to Postfix was a good decision for me. I suggest that it would be for you too. YMMV. Good luck! Bob
