[horde] [ingo] [sieve] which TLS certificate is in use

[Carsten]

Hi List,

I am struggling around with INGO and the TLS issue, when trying to 
update the script files.

Either the horde frontend (apache2) and the dovecot have their own 
certificate, signed from my own ca, which of couse is in the trusted ca 
store on the server.
Both are installed on the same server -so "only" a localhost connection.

To get a better understanding, of what happens, I would like to know, 
which certificate is in use, when ingo tries to connect to the sieve 
service?

Is it sending the apache2 ssl certificate from the frontend,
or is the ssl certificate from dovecot in use
or is it neither of them and it generates some other certificate?

I do not want to disable tls as a workaround, because there will be some 
external connections coming from the thunderbird plugin.
