I will check this out later because I want to understand what was going on, but I am happy to report that switchng to the system-wide fetchmail, a unit for which was already in systemd (but which was prevented from doing anything by /etc/default/fetchmail, and by the fact it was unconfigured) has solved the problem. So as described in a mail I wrote last night, I've moved my .fetchmailrc to /etc/fetchmailrc (which is not an obnoxious thing to do on this machine because I am the only habitual user) and enabled this run of fetchmail in /etc/default/fetchmailrc, and now systemctl start fetchmail and systemctl stop fetchmail start and stop fetchmail meaningfully. (Also had to change the ownership of /etc/fetchmailrc to the user fetchmail, when I copied ~mark/.fetchmailrc to /etc/fetchmailrc as root the result was initially owned by root which given the recommended permissions of 600 wouldn't have worked) I moved my refresh interval from the command line to the fetchmailrc file -- /etc/default/fetchmailrc provides a means to influence the command line but putting all the options in the fetchmailrc felt cleaner, now that I think on it. And then in my original script sudo -u mark fetchmail -q can be replaced with systemctl stop fetchmail, and sudo -u mark fetchmail -d 900 can be replaced with systemctl start fetchmail I made all these changes last night and got up this morning to find everything working as it should be. So this issue is now downgraded from an actual issue to a research project of why it wasn't working the old way. Which I will still be investigating and will post if I find something interesting. Thanks to all, especially in this case Nicolas, for your help and suggestions. Mark
