it would be very helpful if you could post the output of 'doveconf -n'.
Please see below:
thank you very much.

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.

Markus
