I'm starting to see the following error when upgrading from 2.2.27 to 2.2.29.

doveadm(ip.add.re.ss): Error: doveadm client disconnected before handshake: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher

Downgrading from 2.2.27 resolves, error still persists in 2.2.28.

I'm using openssl 1.1.0.f and an ec cert/key with the following curve. ASN1 OID: prime256v1 NIST CURVE: P-256

Does anyone know anything about this off the top of their head? If not I'll try to git-bisect 2.2.27 -> 2.2.28 and see if I can find any offending commits later on this week.

That would indicate a problem with cipher lists. What are you doing that causes this?

I'm dealing with a pretty vanilla config.

The only ssl related settings are as follows.

ssl_cert =

local_name domain.com { ssl_cert =

mail_replica = tcps:replica.hostname:port

When I turn up the ssl debug logging all I get the following.

Hi,

I compiled 2.2.30.2 and Clucene, looks like the message disappeared.

Now, the search does not work when the number of input characters are below 6. How to change that limit (to 3 for instance) ? Thank you very much

Hi,

I can not get rid of the below message and my FTS seems not working properly. Is there a compile parameter to adjust to have Lucene working ?
