SoGo is slow, and often shows "service unavailable" error messages".

In dovecot's sieve.log, I see:

Nov  8 14:45:09 iredmail dovecot: managesieve-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<MOAEfpmzhr9/AAAB>

I don't recall making any changes which could impact this, but I must have done something. I cannot see anything problematic in dovecot.conf, but I am not sure what I am looking for.

Any thoughts on debugging / remedying this would be welcome.

Thanks for your help!

SOGoIMAPServer = "imap://127.0.0.1:143/";
    SOGoSMTPServer = 127.0.0.1;
    SOGoSieveServer = "sieve://127.0.0.1:4190/?tls=YES";

Try this setting and restart sogo service:

SOGoSieveServer = "sieve://127.0.0.1:4190/?tls=YES&tlsVerifyMode=allowInsecureLocalhost";
