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.

I'm dealing with a pretty vanilla config. 


The only ssl related settings are as follows.

ssl_cert                        = </etc/ssl/ecc.cer
ssl_key                         = </etc/ssl/ecc.key

local_name domain.com {
  ssl_cert                      = </etc/ssl/domain.com.ecc.pem
  ssl_key                       = </etc/ssl/domain.com.ecc.key
}

mail_replica = tcps:replica.hostname:port


When I turn up the ssl debug logging all I get the following.
>From the host where mail is being replicated to;

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 ?

doveadm(root): Debug: Skipping module doveadm_fts_lucene_plugin, because
dlopen() failed:
/usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_lucene_plugin.so: undefined
symbol: lucene_index_iter_deinit (this is usually intentional, so just ignore
this message)
doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen()
failed: /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so: undefined
symbol: fts_backend_rescan (this is usually intentional, so just ignore this
message)

Thank you very much

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
