TLS Error and not working lmtp

Hi!

I have some troubles with the virtual plugin. I run a self-compiled
dovecot 2.2.33.2 from debian testing. I patched this version with the
QRESYNC-Patch from a few weeks ago.
But i always get an errormessage, when i try to open an email from a
virtual mailbox.

So i cloned the actual git-Repo and compiled dovecot and pigonehole-sieve.

The problem with the virtual plugin seems gone away. But there are some
other problems.
I use ssl=required and with dovecot from debian TLS/SSL and STARTTLS
works fine.
With the selfcompiled from git, i get this error:

dovecot[1284]: imap-login: Error: Failed to initialize SSL server
context: Couldn't parse DH parameters: error:0906D06C:PEM
routines:PEM_read_bio:no start line: Expecting: DH PARAMETERS: user=<>,
rip=127.0.0.1, lip=127.0.0.1, secured, session=<D6bC4Rlg8ut/AAAB>

The key and crt are exactly the same files as before.

The second problem is, lmtp is not working. I use exactly the same
config for the debians dovecot and dovecot from git. But in the
gitversion the error in exim is:

Failed to connect to socket /var/run/dovecot/lmtp for dovecot_lmtp
transport: Connection refused

My config is:

# dovecot -n
# 2.3.devel (b1aac3a1d): /usr/local/etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.devel (624e1769)
