Greetings, after years when everything worked without a hitch, mutt started to say "connection timed out" every ten minutes or so when connected to my remote dovecot imap server. I would need help to figure out where the problem is, on the client or server side, and then how to fix it. Details already are in the dovecot mailing list here https://dovecot.org/pipermail/dovecot/2021-April/121897.html
Thanks in advance for any help, Marco
