Thanks for your answers!
I have those lines, but when connecting, I get in /var/log/mail.log:
2024-04-28T12:48:26.620893+00:00 2x5 cyrus/https[35045]: inittls: Loading hard-coded DH parameters
2024-04-28T12:48:26.622823+00:00 2x5 cyrus/https[35045]: Fatal error: Failed to set SASL property
I have, on the other side, no problems with imap connections,
only with https.
Any hint what this error means?
Thanks
Rod.
