Hello,
after upgrading from Fedora 42 to Fedora 43 the dovecot got upgraded to
version 2.4.
I tweaked the configuration, dovecot starts, but when client is trying to
connect to imap, I get:
imap-login: Error: Failed to initialize SSL connection: Couldn't
initialize SSL server context: Can't load SSL certificate
(ssl_server_cert_file setting): error:0A00018F:SSL routines
::ee key too small:
I tried replacing 2048 bits RSA with 4096 bits RSA, I tried to not use the
dh.pem file (I read somewhere it is not neede any more), I deleted
/var/lib/dovecot/ssl-parameters.dat file, but still the same error.
Where should I look next?
My ssl config:
ssl = required
#ssl_server_dh_file = /etc/dovecot/dh.pem
ssl_server {
#ssl_server_dh_file = /etc/dovecot/dh.pem
ssl_server_cert_file = /somewhere/dovecot.pem
ssl_server_key_file = /somewhere/dovecot.pem
prefer_ciphers = server
}
ssl_min_protocol = TLSv1.2
ssl_cipher_list = PROFILE=SYSTEM
#ssl_verify_client_cert = no
#ssl_prefer_server_ciphers = no
Thanks
Marek
