your messages log will have the answer and also the last thing in your terminal when it disconnected
if you have nextcloud or a lot of users signal event could take a long time.
Using server manager the current 'messages' is full of:

briefly there was:

But I found yesterdays log and I see this which relates to the install from the smetest:
Mar 23 13:50:13 sme10 systemd-logind: New session 511 of user root.
Mar 23 13:50:56 sme10 yum[14831]: Installed: smeserver-roundcube-1.2-23.el7.sme.noarch

later followed by:
Mar 23 15:59:44 sme10 kernel: [79829.913093] perf: interrupt took too long (3924 > 3917), lowering kernel.perf_event_max_sample_rate to 50000
Mar 23 15:59:44 sme10 kernel: perf: interrupt took too long (3924 > 3917), lowering kernel.perf_event_max_sample_rate to 50000
and
Mar 23 17:40:03 sme10 rsyslogd: imjournal: journal reloaded... [v8.24.0-57.el7_9.3 try http://www.rsyslog.com/e/0 ]
After that it runs the backup operation and nothing more that could be related.
I'm not sure how to interpret the log - the system believes that roundcube is installed but something has gone astray but
I'm not sure how to move forward as roundcube isn't available and the issue with sending mail from a different app is still present.
