it would be very helpful if you could post the output of 'doveconf -n'.
Please see below:
thank you very much.
service imap-login { client_limit = 1000 process_min_avail = 1 service_count = 0 }
As you didn't change other settings of this service, I think this should be fine.
And as you also didn't change these parameters (shown with their defaults):
auth_mechanisms = plain disable_plaintext_auth = yes ssl = yes
they should have their default values too. This means that a client is allowed to use plaintext authentication, but only if SSL/TLS is used, which isn't the case according to the defaults you use for
service imap-login { [...] inet_listener imap { [...] port = 143 ssl = no <-------- disables SSL/TLS
In the end I assume that despite you can connect to port 143 unencrypted, Dovecot doesn't accept the plaintext authentication. Could that be the case or am I misunderstanding your current situation/problem?
So I think one option would be to set:
disable_plaintext_auth = no
in /etc/dovecot/conf.d/10-auth.conf to allow your clients to connect to port 143 without SSL/TLS and authenticate with a plaintext mechanism (only 'plain' is allowed at the moment).
If my assumptions are wrong, then please send an appropriate log file entry when a client tries to connect to port 143.
