update on this: to make a long story short....
1) I did run mutt with debug enabled , but could not recognize anything useful 2) I had the same problem with mutt from my laptop 3) a few days ago I received a new modem from my ISP, as part of their network upgrade operations 4) more or less in the same moment the problem I reported here disappeared. Now mutt stays connected even 24 hours without losing connection. I am NOT 100% sure that the problem disappeared AFTER the change of modem. That happened during a few chaotic days, both work- and family-wise, so I did not take notes. And modems may have nothing to do at all with the disconnections. But now the problem is not there anymore, I have no clue what may have happened, and if anybody can guess... thanks in advance. Il giorno mar 13 apr 2021 alle ore 15:37 Kevin J.
