Okay, Viktor! I executed these commands and got this result:
$ dnsname=mailserver.mail.lan
$ rm certkey.pem
rm: Unable to delete 'certkey.pem': No such file or directory
user@mailserver:~$ openssl req -new -nodes -newkey rsa:2048 -keyout /dev/stdout
\
-config <(printf 'distinguished_name=dn\n[dn]\nprompt=yes\n') -x509
-subj / -days 3653 \
-addext "basicConstraints = critical,CA:FALSE" \
-addext "extendedKeyUsage = serverAuth" \
-addext "subjectAltName = DNS:$dnsname" >> certkey.pem

But the 465/SSL mail is still not accepted.
The PF logs still have the same lines:

What else do I need to do?
