Hello together

Please i'am new to this list, i have already installed Postfix and 
Dovecot last version from Internet
but i have the porblem that the mail do not arive, and with me Cert, i 
have read on the Dovecot site,
but i don't have me found me solutions to fix this. "tlsv1 alert unknown 
ca: SSL alert number 48"

Jan 28 22:42:44 dovecot: imap-login: Disconnected (no auth attempts in 0 
secs): user=<>, rip=192.168.1.16, lip=192.168.1.3, TLS: SSL_read() 
failed: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown 
ca: SSL alert number 48, session=

# dovecot --version
2.2.27 (c0f36b0)

i think that the settings about Cert are done, but if connecting with 
Thunderbird i will become this error
"tlsv1 alert unknown ca: SSL alert number 48"

Please you can point me to the right direction, so i can run this 
Mailserver on me RaspverryPi.
Regards
Mauri
