Gracias Alberto. Now it's solved (it has been a little bit tricky).
My final config:
* /etc/imapd.conf
tls_ciphers: TLSv1.2:TLSv1:HIGH:!aNULL:@STRENGTH
tls_versions: tls1_0 tls1_1 tls1_2 tls1_3
* /etc/ssl/openssl.cnf
MinProtocol = TLSv1.0
CipherString = DEFAULT@SECLEVEL=2
Still don't know how t
Hi,

(imaps & pop3s) stopped negotiating TLS 1.0 and 1.1 protocols (I know

Take care when you try to analyze the rootkit: You should install new
into another partition/ boot from live cd first and then look at the
files without executing them (otherwise your new system may get
infected). The rootkit may be altered, removed or your activity may be
monitored and/or in

That shows all open tcp and udp ports. Invoke this before you start
